By conducting diagnostics to enable efficient operation, we contribute to energy savings and CO2 reduction. [Examples of Diagnostics] ■ High fuel costs for the boiler ■ Long heating time for the boiler *For more details, please download the PDF or feel free to contact us.

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.

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.

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.

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.*

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 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.

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.

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. [Diagnosis Examples] ■ High fuel costs for the boiler ■ Long heating times for the boiler *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. [On-site Issues] - Sludge does not settle in the downstream sedimentation tank. - Treated water is cloudy. - It seems that microorganisms are not functioning properly. *For more details, please download the PDF or feel free to contact us.*

We would like to introduce a case where we proposed energy-saving boiler chemicals containing scale removal components to a certain chemical manufacturer in the Tokai region, specifically to the boiler personnel. In the boilers used in manufacturing sites, scale (solid deposits) accumulates inside the pipes over time, leading to issues such as the labor and costs associated with regular scale removal work. In response to these challenges, we proposed our chemical. By switching to our product, we achieved gradual detachment of the scale adhered to the boiler pipes and suppression of re-adhesion. [On-site Challenges] ■ Fuel loss due to decreased heat transfer efficiency ■ Extended heating time ■ Labor and costs associated with regular scale removal work *For more details, please download the PDF or feel free to contact us.

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.*

To the boiler equipment personnel of textile manufacturing companies in the Tokai region, We would like to introduce a case study on our proposal for improving used boilers and chemicals. We faced concerns regarding the boiler that had been in use for many years, particularly regarding poor fuel efficiency and the increasing running costs year by year. We started by thoroughly examining the current boiler chemicals and switching to more suitable ones. After that, we proposed a plan to utilize a good-condition used boiler from our company. 【Background and Challenges on Site】 ■ The response from the maintenance company is slow, and deficiencies are found even during regular inspections. ■ Fuel efficiency is poor, and running costs are increasing year by year. ■ Future expansion of the boiler system is being considered, but costs are a bottleneck. ■ The aging of the boiler has led to a decrease in heat transfer efficiency. ■ The chemicals being used do not match the current water quality, raising concerns about scaling and corrosion. ■ Although considering an update, the high cost of introducing a new boiler has put it on hold. *For more details, please download the PDF or feel free to contact us.*

We would like to introduce a case study of the implementation of an automatic control system for industries such as aluminum processing, metal processing, surface treatment, and extrusion molding, where pH management of factory wastewater is required. We received inquiries expressing concerns that the pH of the wastewater sometimes shows abnormal values and that there might be a risk of it flowing out externally. Abnormal pH levels in wastewater can occur suddenly, and there are limitations to monitoring and responding manually. Our proposal was to implement a system that automatically controls an electric valve in conjunction with the pH meter readings. After implementation, we achieved zero outflow of abnormal water, and real-time responses to pH anomalies became possible. 【Challenges on-site】 ■ The pH of the wastewater sometimes shows abnormal values, raising concerns about potential external outflow. ■ If water exceeding the standard value were to flow out, it could lead to environmental standard violations or issues with neighboring areas. ■ Continuous monitoring by human resources is difficult, so we want to implement automatic safety measures. *For more details, please download the PDF or feel free to contact us.

To the equipment managers at sites with heating processes such as food factories and beverage manufacturing, we have proposed updating boilers by converting fuel from heavy oil to gas. The heavy oil boiler, which has been in use for over a decade, has reached a point where performance degradation and increasing repair costs necessitate consideration for an update. In this context, we focused on the subsidy program for introducing energy-saving equipment through fuel conversion. After implementation, we significantly reduced initial costs by utilizing subsidies, stabilized fuel expenses, and made cost forecasting easier. 【Challenges on-site】 ■ Repairs are not keeping up ■ If we are going to update, we want to reduce utility costs as much as possible ■ There are budget limitations *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. [On-site Challenges] ■ Stopping production for cleaning each time there is a clog ■ Additional labor and time required for cleaning ■ Significant power consumption due to air usage *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.

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.

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.
