There are actually many places in factories where pH is measured. Depending on the purpose and location, the shape of the equipment and the measurement method vary. ■ Uses range from "quality control" to "environmental monitoring" The applications of pH measurement are very broad, covering everything from process management in product manufacturing at factories to pollution monitoring of factory wastewater and river water. Both management to maintain consistent product quality and management to ensure that discharged water meets standards are capturing the state of water using the same measure: pH. ■ Choose the shape and measurement method according to usage The shapes of the equipment include portable handheld types, desktop types for use on tables, and fixed types for continuous monitoring installed in facilities. There are also multiple measurement methods, including indicator reagent types that show color changes, antimony electrode types, and glass electrode types that offer superior accuracy. Choosing between convenience and accuracy or continuous monitoring is essential. Selecting the right combination for your application is the first step toward proper water quality management. You can find an explanation of how to choose pH management and water quality measurement equipment suitable for your needs in this document. Please download the document!

The pH, which is fundamental to water quality management. There are two methods for measuring it: using precise instruments and convenient test strips, which are chosen based on the purpose. ■ pH Meter (measures accurately with electricity) A pH meter is an electrical measuring device that uses an internal glass electrode. When two types of solutions are separated by a glass membrane, a potential difference arises according to the difference in pH between the two. By utilizing this mechanism, the potential generated between the reference solution inside the electrode and the water to be measured is read to accurately quantify the pH. However, to maintain accuracy and reliability, it is necessary to regularly perform "calibration" (adjusting to correct values) not only when starting to use it or when replacing the electrode but also during use. ■ pH Test Strips (easy determination by color) pH test strips are paper that determines the approximate pH of a liquid by color change. They start as green, and when immersed in a liquid, they change from red (acidic) to green (neutral) to blue (alkaline) depending on the pH. For example, if a strong acid like sulfuric acid is present, it will show red. While they are less accurate than instruments in terms of numerical precision, their strengths lie in the fact that they do not require power or calibration, allowing for quick assessments of acidity or alkalinity on the spot. The appropriate methods for pH management and water quality measurement according to your needs are explained in this document. Please download the document!

Even though a water softener is installed, hard water continues to come out. This phenomenon has a clear mechanism and prevention method. ■ What is hardness leakage? A water softener uses a material called ion exchange resin to remove hardness components (calcium and magnesium) contained in tap water to produce soft water. However, there is a limit to the amount of hardness components that this resin can absorb. Once the removal continues to a certain extent, the resin becomes saturated and stops functioning, allowing hard water to pass through unchanged. This is called hardness leakage. ■ "Regeneration" is essential to avoid it The key to prevention is the process of "regeneration," which involves regularly cleaning the resin to restore its function. Salt (sodium chloride) is used for this. Rinsing the resin with a saltwater solution of about 10 percent separates the hardness components that were attached to the resin, returning it to its original clean state. If this regeneration is not performed regularly, the benefits of soft water will not be achieved even if a water softener is installed. Ignoring hardness leakage can also lead to scale (deposits similar to limescale) in boilers and piping. The methods for regenerating a water softener and managing water quality are explained in this document. Please download the document!

The water coming out of the softener is unexpectedly hard. This "hardness leakage" can be addressed more quickly if the cause is identified. ■ What is hardness leakage? A water softener uses ion exchange resin to remove calcium and magnesium (hardness components) from water to create soft water. This resin is regenerated with brine and reused, but if there is some malfunction, hardness components can mix with the treated water, resulting in hardness leakage. If left unaddressed, it can cause scale (deposits similar to limescale) in boilers and piping. ■ Causes can be categorized into four main patterns The cause can be identified by the symptoms. 　❶ If the hardness of the treated water is the same as that of the raw water, it may be due to forgetting to regenerate, forgetting to add salt, salt clumping in the salt tank, or clogging in the chemical injection line—indicating that "regeneration is not functioning." 　❷ If it leaks from the beginning, it may be due to water bypassing the resin layer or insufficient salt leading to poor regeneration. 　❸ If it suddenly leaks while the water intake is low, it may be due to poor regeneration, resin washout, or a sudden change in raw water hardness. 　❹ If it leaks gradually, it may be due to resin degradation or the adhesion of iron and silica, indicating "reduction in resin performance." How to identify the cause and proceed with resin replacement and water quality management is explained in this document. Please download the document!

⬛️ What is water concentration? Water concentration refers to the phenomenon where the concentration of impurities, such as mineral components dissolved in water, becomes higher as moisture evaporates. A familiar example is miso soup. When it is heated and reduced, it becomes thicker and saltier because only the moisture evaporates, leaving the components of the miso intact. Even if the water itself decreases, the dissolved components do not escape and become concentrated. ⬛️ If concentration is left unattended, pipes can clog and iron can rust. The same thing happens in boilers and cooling towers. As operation continues, moisture evaporates and the components in the water become concentrated. If it becomes too concentrated, the components can solidify and adhere to pipes and heat transfer surfaces, causing scale (similar to deposits) and corrosion, which directly leads to decreased thermal efficiency and equipment troubles. Measures such as "blowing down," which involves discharging a portion of the concentrated water and replenishing it with fresh water, and regular water quality management are essential. The approach to water quality management and scale prevention for boilers and cooling towers is explained in this document. Please download the document!

When it comes to boiler failures, people tend to imagine a large explosion, but the gradual progression of "corrosion" is also a significant factor that affects the lifespan of the equipment. ⬛︎ Types of Corrosion Corrosion in low-pressure boilers can be broadly classified into general corrosion, where the metal surface uniformly diminishes, and localized corrosion, where only specific areas are intensely affected. Localized corrosion includes pitting, which progresses deeply in spots, and crevice corrosion, which occurs at overlapping parts of components. From the perspective of maintaining healthy operation, localized corrosion is particularly concerning. Even if the overall structure appears sound, localized areas can progress deeply, leading to holes or leaks. ⬛︎ Key Points for Countermeasures To mitigate corrosion, managing water quality is fundamental. Specifically, it involves maintaining an appropriate pH (between 11.0 and 11.8), keeping harmful corrosive components below standard levels, removing dissolved oxygen (oxygen dissolved in water) that promotes corrosion, and ensuring that water is always flowing to prevent stagnation. Continuous maintenance of these factors requires regular water quality testing and chemical adjustments. Measures against corrosion through water treatment and guidelines for inspecting boiler equipment are explained in this document. Please download the document!

◼️ What is a steam trap? While steam is flashy, the real troublemaker in a factory's steam piping is the "water" that forms when steam cools. A steam trap is a device that automatically discharges condensate (drain) that accumulates in equipment and piping handling steam, such as boilers. It holds back the steam and allows only the condensate that has turned into water to escape. It can be understood as a "checkpoint that lets water through but not steam." ◼️ Purpose of installation When condensate accumulates in the piping, high-speed steam pushes the water out, causing water hammer (hydraulic shock) that impacts the piping and fittings. It is installed to prevent damage to equipment and leaks. ◼️ Points to be aware of There are multiple types of traps, such as bucket-type, each with different structures, so it is essential to understand the type when repairing or replacing them. Additionally, failures have two faces. If it breaks while closed, the condensate will not be discharged, leading to issues; if it breaks while open, steam will continue to leak, quietly wasting fuel. The latter is harder to notice, making regular inspections important. The structure of traps and how to conduct inspections and energy-saving diagnostics are explained in this document.

The unique smell of the wastewater treatment plant. Are you just brushing it off with "Well, it's that kind of place, so it can't be helped"? In fact, that smell is a sign that can be life-threatening for workers. ■ The source of the smell like rotten eggs A typical foul odor generated in wastewater treatment is hydrogen sulfide (H2S, which smells like rotten eggs). The troublesome part is that its specific gravity is about 1.2 times that of air. This means it is heavier than air and accumulates in "low places" such as pits and tanks. While the smell may be faint above, there is a risk of suddenly plunging your head into a high-concentration layer when you bend down. ■ Moreover, the danger of "getting used to it" Hydrogen sulfide has a strong odor at low concentrations, but at high concentrations, it can numb the sense of smell, making it undetectable. This does not mean "it smells less than before = it has become safe"; rather, it indicates that you may have entered a dangerous zone. The inability to use the presence or absence of smell as a safety gauge is the most frightening aspect of this substance. Other foul-smelling substances, such as methyl mercaptan (which smells like rotten onions) and ammonia, also exist, each with different properties. We have summarized methods to ensure safety in wastewater treatment plant inspections not relying on smell but on systems in this document.

In mass production settings, the task of weighing various types of raw materials in grams is burdensome. By weighing these raw materials and providing them in one package, the weighing process itself can be outsourced. ◼️ Benefits of One-Packing - Multiple raw materials (such as salt, sugar, spices, and extracts) are pre-mixed. We deliver them in a state where you only need to "add one bag at a time" on-site. - This prevents "flavor inconsistencies" and "rework" caused by weighing errors. ◼️ Reduction of Raw Material Waste and Streamlining Inventory Management - "Reduction of waste loss": There is no need to individually stock spices and additives that are used in small quantities, significantly reducing the risk of waste due to expiration. - "Simplification of material management": By consolidating 10 types of raw materials into one "special seasoning (blended seasoning)," we compress the costs of ordering, inspection, and storage space.

We received an inquiry from a customer at a confectionery manufacturer stating, "Using sugar as an ingredient makes the dough prone to burning during baking, which worsens the manufacturing yield." ◼️ Issues - We want to add sweetness without burning the dough. - We want to get as close as possible to the sweetness of sugar. Sugar is prone to undergoing the Maillard reaction during heating, which creates color and aroma, but in some products, it can also cause "burning." Therefore, a replacement with a sweetener that is less likely to burn was required. ◼️ Proposal We proposed a blend that utilizes the characteristics of natural and synthetic sweeteners to replicate a natural sweetness close to sugar by controlling the onset of sweetness (the speed at which it is perceived) and the aftertaste.

Due to company policy, we cannot handle "non-pharmaceutical toxic substances." Toxic substances are materials other than pharmaceuticals that have strong toxicity and require special care in handling. Chemical substances designated as toxic under the "Poisonous and Deleterious Substances Control Law" are classified as "non-pharmaceutical toxic substances." When using toxic substances, one must be a "business handler," and various precautions must be taken regarding handling methods and responses in case of leaks, which limits the number of employees who can handle them. Our company will deliver toxic substances diluted to a predetermined concentration. Please refer to the downloadable materials for more details on our proposal.

The effectiveness of the ion exchange resin is declining! The conductivity of the soft water is increasing! In the boiler equipment that supports the manufacturing line, a stable supply of high-quality pure water is crucial. There has been a challenge where the effectiveness of the ion exchange resin in use on-site is gradually decreasing, leading to an increase in the conductivity of the pure water. Furthermore, although the resin regeneration was set to occur automatically, there were concerns that starting regeneration during operation could impact production, leading to requests for control over the timing of regeneration.

Do you have any concerns regarding the handling of sodium hypochlorite at pool or water treatment facilities? - The conventional 20kg containers are too heavy, making transportation and injection work a heavy burden for specific staff. - When pouring the liquid, there is a "gobble" splash (liquid splatter), raising concerns about skin contact, clothing discoloration, and labor accident risks. - It cannot be used up in one go, leading to anxiety over accidents during storage and handling management. The lightweight sodium hypochlorite (15kg) fundamentally resolves these issues at the work site. ◇ Excellent operability due to 25% weight reduction The weight is reduced to 15kg while maintaining the same specifications as the conventional 20kg container. This minimizes the burden of carrying and allows various workers to handle it smoothly. ◇ Stable design that reduces liquid splatter risk The weight reduction stabilizes the balance during pouring. It suppresses the "gobble" splashing phenomenon and prevents chemical contact accidents. ◇ Optimization of management burden and introduction costs By handling smaller quantities, storage risks are reduced. The introduction cost can also be offered at the same level as the conventional 20kg product. We are currently offering free case studies to improve work safety and eliminate burdens.

To the chemical manufacturers, we would like to introduce a case where we visualized the internal condition of a boiler and conducted internal cleaning of the water supply tank. We received inquiries expressing concerns that the efficiency of the boiler seems to be declining, fuel consumption is increasing, and steam generation is poor. As we investigated further, the possibility arose that iron content in the raw water was gradually accumulating inside the boiler. First, we used a fiberscope to visualize the internal condition of the boiler. As a result, reddish-brown deposits were observed on the heat transfer surfaces and inside the piping, confirming the accumulation of iron. Additionally, to address the raw water side of the boiler, we conducted internal cleaning of the water supply tank. It became clear that iron rust was settling at the bottom of the tank, indicating that the root cause was the carryover from the raw water. [On-site issues] ■ The efficiency of the boiler seems to be declining. ■ Fuel consumption is increasing, but steam generation is poor. ■ Iron content may be related. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study regarding the introduction of an automatic chemical injection pump to the site manager of a major automotive parts manufacturer's painting booth. In the water curtain type painting booth used in the painting process of automotive parts, excess paint mixes with the circulating water and generates sludge (precipitate). However, this sludge was causing a range of complex problems. To address these issues, we introduced a circulating water treatment agent for the painting booth and an automatic chemical injection pump. This combination reduced the moisture content of the sludge and minimized the risk of chemical excess or deficiency. 【On-site Challenges】 ■ Prone to adhesion and deposition on tanks, pipes, and pumps ■ Cleaning takes time, resulting in a heavy maintenance workload ■ Changes in water quality can easily lead to odors and chemical loss *For more details, please download the PDF or feel free to contact us.

We proposed a total solution for our customers who have requested boiler maintenance, conducting both maintenance and smoke emission measurements simultaneously. Some customers expressed that they rely on other companies for smoke emission measurements, but find the scheduling process cumbersome and inconvenient. In response, we proposed a total solution that includes smoke emission measurements along with boiler maintenance. This reduces the number of steps needed for scheduling to just one, cutting down on coordination efforts and eliminating the hassle of selecting measurement contractors and arranging contracts. [On-site Issues] ■ Smoke emission measurements are outsourced to other companies, but scheduling is cumbersome and inconvenient. ■ It would be more efficient if measurements could be done simultaneously with maintenance. ■ Coordination of on-site schedules with different contractors. ■ Conducting measurement work again after maintenance. ■ Measurement results are not linked to maintenance details. *For more details, please download the PDF or feel free to contact us.

To the maintenance personnel of mold manufacturing companies in the Tokai region, we would like to introduce a case study regarding the review of the stirring method for the raw water tank. The raw materials used for forming paper mold products need to be uniformly stirred and circulated in the raw water tank. Traditionally, an air stirring method was employed; however, the air piping regularly became clogged, necessitating ongoing cleaning efforts. To resolve this issue, we propose switching from air stirring to an electric stirring mixer method. After the switch, we achieved complete elimination of air pipe clogging by stirring directly from inside the tank without using piping.

We would like to introduce a case of updating the diffusers in the aeration tank at factories with wastewater treatment facilities, such as fiber, dyeing, and silk factories. The water quality in the wastewater treatment tank changed at a certain point. There were concerns that the strong odor indicated that biological treatment was not effective. First, we temporarily halted the aeration equipment on-site and conducted an investigation of the air piping. It was discovered that the diffusers (aeration devices) that should have been installed at the bottom of the aeration tank were missing. We immediately reinstalled and inspected the diffusers, confirming normal aeration and recovery of the dissolved oxygen (DO) levels. [On-site concerns] - The water that used to be gray has turned dark. - The DO (dissolved oxygen concentration) is not increasing at all. - There is a strong odor, and it seems that biological treatment is not effective. *For more details, please download the PDF or feel free to contact us.*

We would like to introduce a case of maintenance and cleaning/recalibration of the DO meter at the wastewater treatment facility of a fiber manufacturer and dyeing factory. One day, an anomaly occurred in the biological treatment tank that processes factory wastewater. Various responses were attempted on-site, such as increasing aeration and adding chemicals, but no decisive improvement was achieved, and the overall instability of the treatment tank continued. We suspected a decrease in DO (dissolved oxygen) concentration within the biological treatment tank. Although no significant abnormalities were observed in the DO meter's displayed values, upon performing maintenance and cleaning/recalibration of the sensor, it became clear that the actual dissolved oxygen concentration was significantly lower than the measured values displayed. Based on this cause, we reviewed the aeration conditions, resulting in a recovery of microbial activity, which ultimately led to improvements in sedimentation.

We conduct "Energy-saving Diagnosis for Boilers." Through the energy-saving diagnosis of existing boiler equipment, we identify waste in utility costs. The first items to check during the diagnosis are the efficiency of the boiler itself, which generates steam, and the operational management to ensure that the boiler can operate at that efficiency. It is important to select the most efficient boiler possible when installing one. However, even if a high-efficiency boiler is chosen, if it is not operated in a way that allows it to perform at its best, the efficiency will decrease. By conducting a diagnosis and implementing efficient operations, we contribute to energy savings and CO2 reduction. If you have any concerns regarding boiler energy efficiency or heating efficiency, please feel free to consult us. We support the reduction of waste and stable operation through diagnosis and improvement proposals tailored to the local situation.

We proposed a review of wastewater treatment to the person in charge at automotive parts manufacturers, painting factories, and electrodeposition painting lines that have wastewater treatment facilities. We received inquiries about wanting to improve the water quality of treated water, which sometimes exceeds the standard values. Upon inspecting the site, we found that multiple equipment-related issues were overlapping. We simultaneously proposed and implemented three points: updating the dewatering machine, relocating the piping in the aisle, and installing a new diffuser along with updating the blower piping. As a result, the water quality stabilized, there were no longer any exceedances of the standard values, dewatering treatment kept pace, and the accumulation of sludge was resolved. [On-site Issues] ■ The water quality of treated water sometimes exceeds the standard values, and improvements are desired. ■ When problems occur with wastewater treatment, it affects the entire factory's operations, so a fundamental review is needed. ■ There are concerns about the safety of workers as they might trip over the piping in the aisle. *For more details, please download the PDF or feel free to contact us.

To the person in charge of equipment maintenance at the automotive parts electrocoating factory in the Tokai area, we would like to introduce a case where we proposed a compliance boiler. When updating the boiler, there was a challenge of high estimates from existing vendors, making it difficult to proceed with the update. Additionally, not only the "price of the equipment itself" but also the "labor and procedures related to operation" became hidden costs. In response to these concerns, we proposed solutions from three perspectives: cost, regulatory compliance, and maintainability. The new boiler we proposed has high combustion efficiency, allowing for reductions in fuel and water supply costs compared to conventional models. [On-site Challenges] ■ High estimates from existing vendors make it difficult to proceed with the update. ■ Due to regulatory compliance, smoke measurement and notifications are required, leading to a significant operational burden. ■ Running costs are increasing, and regular maintenance and chemical management are also cumbersome. *For more details, please download the PDF or feel free to contact us.

To the personnel in charge of drainage treatment maintenance and environmental management, we would like to introduce a case regarding the proposal for the introduction of a coagulant dosage control device. Coagulants are essential for wastewater treatment in manufacturing sites, but traditionally, a fixed amount was added regardless of the characteristics of the raw water. This led to issues such as wasted chemical costs and instability in floc quality. To address these problems, we proposed the introduction of a coagulant dosage control device. By implementing this device, it became possible to optimize chemical usage while improving treatment efficiency. [On-site Challenges] ■ The chemical dosage is fixed even though the concentration and load of the raw water fluctuate daily. ■ There is a tendency for coagulation to be excessive or insufficient, leading to inconsistencies in treatment efficiency. ■ Wasted chemical costs and instability in floc quality. *For more details, please download the PDF or feel free to contact us.

To the boiler operation managers and equipment personnel of tourism and leisure facilities, We would like to introduce a case where we proposed a used water softener. A stable supply of softened water to the boiler is essential for operating the experience train modeled after a steam locomotive. However, the water softener that had been used for many years broke down, leading to the following issues: Our company proposed a used water softener after carefully listening to the situation and budget. Even though it is used, it can perform adequately with proper maintenance and inspection. In this case, we prioritized the quick resumption of supply and provided one-stop service from installation to test operation on-site. **Issues** - Unable to treat boiler feed water with softened water, increasing the risk of scale. - Difficulties in continuing operations, raising concerns about train service interruptions. - Due to being a public facility, securing an unexpected high budget is challenging. *For more details, please download the PDF or feel free to contact us.*

We would like to introduce a case study on the introduction of high-efficiency mixers to reduce electricity costs at a wastewater treatment plant. To reduce electricity costs, it is first necessary to identify areas with high electricity consumption within the wastewater treatment plant. A field survey was conducted to determine where the load is concentrated throughout the entire wastewater treatment process, from the neutralization tank to the sedimentation tank. By replacing the mixers used for aeration in the raw water tank and aeration tank with high-efficiency mixers, we successfully reduced electricity costs. For a customer in the paper industry, the annual electricity cost was reduced from 860,000 yen to 670,000 yen, achieving a 50% reduction. [Case Summary] ■ Benefits of introducing high-efficiency mixers - In addition to reducing electricity costs, switching to high-efficiency mixers prevents sludge settling, ensures uniform mixing, and suppresses scum formation. - We offer a wide range of solutions for stirring, mixing, and generating water flow in various water-related facilities across industrial and water quality environmental sectors. *For more details, please download the PDF or feel free to contact us.

We received a message from the boiler manager of a certain chemical manufacturer’s factory. "Recently, the efficiency of the boiler has been declining. Is there any way to improve the efficiency?" The first thing our employee suspected was the deterioration of thermal efficiency due to scale buildup. Scale, in the first place, is a deposit of minerals such as magnesium, calcium, and silica that are contained in water. A common example of scale is the limescale that accumulates in kettles and electric pots. *For more details on the column, you can view it through the related link.

The chemicals managed by those in charge of the pool are familiar substances. It is a liquid called sodium hypochlorite (bleach), which has a property of being heavier than water. Generally, it comes in a poly tank weighing about 20 to 25 kg, making it very heavy. In the past, we received many comments from school pool managers, such as, "The chemical poly tanks are heavy; is there anything we can do about it?" *For more details on the column, you can view it through the related links.

Today, I will talk about something a bit niche. When I visited the maintenance officer of a paper manufacturing company I have been in contact with for some time, he had a troubled expression on his face. When I asked what was wrong, he said, "The defect rate of our products is high, and we need to do something about it." The paper manufacturing company produces paper by putting raw materials (pulp) into a large tank. When switching raw materials (to produce a different product), there are times when the previously added raw materials stick to the tank and remain as residue, which leads to product defects. *For more details on the column, you can view it through the related link.
