[Case Study of Piping Magnetite Method] Water Quality Inspection in the Water Storage Tank of the Circulating Cooling Water Line

Conducted water quality tests four times! Introducing a case where the piping magnetite method was implemented as a countermeasure against red rust in the cooling water line.

We would like to introduce a case study of NTT-AT Creative Co., Ltd., located in Itano-gun, Tokushima Prefecture, which has implemented our proposed "Piping Magnetite Method." The company has taken measures against red rust in the cooling water line by placing four punch boxes in the water storage tank (10t) of the circulating cooling water line. They collected water from the storage tank every week and conducted water quality tests four times. As a result, water quality improved, and the components of red rust that had dissolved in the water transformed into black rust. The issue of red water was resolved. Additionally, we have materials that cover all topics available for your review. [Case Study] ■ Measures against red rust in the cooling water line ■ NTT-AT Creative Co., Ltd. (Itano-gun, Tokushima Prefecture) ■ Installation of punch boxes (November 12, 2016) *For more details, please refer to the PDF document or feel free to contact us. *The section titled "Trigger for Interest" displayed during the PDF download is generated by the AI of Ipros Co., Ltd.

[Case Study] Cross-checking to Maintain the Accuracy of Drainage Inspections

The separation of orders for drainage inspection and maintenance of pest control facilities has been implemented, and we will introduce cases of factories where the water quality of the drainage tends to exceed the standards!

In a factory where drainage inspection and maintenance of the wastewater treatment facility are separately contracted, our company is responsible for the drainage inspection. In one factory, there was a tendency for the wastewater quality to exceed the standards. As a result, under the administrative penalty system, there was an obligation to pay a specified fee depending on the degree of exceeding the standard values. Therefore, the managing company requested the maintenance company for improvements. The maintenance company then implemented improvement measures and conducted a drainage inspection (separately from our company) to prove the effectiveness of these measures, submitting the inspection results to the managing company. However, the results did not reflect the actual situation (with suspended solids SS at 0 mg/L, indicating no suspended matter at all), and the data was unreliable. By the way, the data from the drainage inspection conducted by our company around the same time was near the standard value (200 mg/L) and yielded different results. Considering such cases, it is deemed effective to conduct cross-checks by a third-party organization like ours when drainage inspections are not separately contracted.

[Case Study] A case where the hot water supply pipe burst once a week.

We will introduce a case where frequent holes appeared in the hot water pipes (copper pipes) of the central hot water supply system at a university hospital, leading to ongoing repairs.

At the university hospital, the hot water supply pipes (copper pipes) frequently developed holes, leading to constant repairs. Inspection results confirmed copper leaching, and it was determined that the high levels of free carbonic acid in the well water used for make-up water—ten times higher than in tap water—were the cause. Free carbonic acid is highly corrosive to copper, so as a corrosion prevention measure, a drinking water rust inhibitor was applied to resolve the issue. 【Overview】 ■Problem - Frequent holes in the hot water supply pipes (copper pipes) leading to constant repairs. ■Solution - Applied a drinking water rust inhibitor as a corrosion prevention measure. *For more details, please refer to the PDF document or feel free to contact us.

Risk avoidance through water quality testing.

From risk assessment to countermeasures! Reduce lifecycle costs with proper management!

Just as blood tests assess the health status of the human body, conducting "water quality tests" allows us to identify the risk of water-related issues in advance and implement preventive measures. Cooling water is prone to four major issues: "scale formation," "algae growth," "corrosion," and "Legionella bacteria." Open cooling towers, in particular, are susceptible to external environmental influences, necessitating measures that correspond to the operational conditions, installation circumstances, and water quality. Additionally, equipment water such as chilled and warm water or make-up water (groundwater) each has its own characteristics, requiring tailored measures based on their specific uses and symptoms. 【Characteristics of Equipment Water】 ■ Cooling Water: Cleaning + Water Quality Management ■ Chilled and Warm Water: Cleaning + Rust Inhibitor Addition ■ Make-up Water (Groundwater): Water Quality Management + Water Quality Improvement (Water Softener) *For more details, please refer to the PDF document or feel free to contact us.

What is a water quality test for well water? Items, frequency, and where to request it [Basic Knowledge]

If you use well water for drinking at your business, the regulations that apply will change the content of the inspection. This will explain the items, frequency, the requesting party, and how to interpret the results.

When using well water for drinking purposes at factories or business sites, there is not just one regulation that serves as the basis for inspection. The starting point is to confirm which category your company's well falls under. ■ Which regulation applies? 1. Dedicated water supply: If supplying water to more than 100 residents or if the maximum daily water supply exceeds 20 cubic meters, it falls under the Water Supply Act. 2. Specific buildings: Buildings subject to the Building Hygiene Act. 3. Business-use drinking wells: Wells that do not fall under the above two categories and supply drinking water to business sites such as factories and stores. If well water is used in employee dormitories or company housing, it may fall under category 1 depending on the number of residents. ■ Business-use drinking wells are governed by national guidelines Category 3 is addressed in the national guidelines for sanitation measures for drinking wells, etc. The guidelines state that if prefectures have established ordinances or regulations, those should be followed. ■ Is a full inspection required before use? The same guidelines stipulate that before starting water supply, a water quality inspection in accordance with the Water Supply Act must be conducted. The Building Hygiene Act also requires that if groundwater is used as a source, all items of the water quality standards must be inspected before starting water supply, with regular inspections continuing thereafter. Please feel free to consult us first.

What is the method for water quality testing? Differences between simple tests and official methods [Basic Knowledge]

A quick method to observe using the color of the reagent and a method to measure according to the procedures set by the government. I will explain the differences between the two uses beyond just convenience.

The methods for water quality testing can be broadly divided into "official methods," which are measured according to standards set by the government, and "simple tests," which are quick ways to obtain values on-site. Rather than one being superior to the other, the choice depends on the purpose of the measurement. In this article, we will refer to quick measurement methods other than official methods as simple tests. ■ What are official methods? The values compared to the legal standards are determined by specific measurement methods. In the regulations that establish discharge standards, it is stipulated that the discharge standards are based on detection values obtained using methods specified by the Minister of the Environment. These notifications specify methods according to various standards, such as the Japanese Industrial Standard K0102. For drinking water, the regulations that set water quality standards also require that tests be conducted using methods established by the Minister of the Environment to ensure compliance with the standards. ■ What is the mechanism of simple tests? A commonly used method involves adding reagents to produce a color and comparing it with a color chart, known as colorimetry. For example, in the DPD method for residual chlorine, 10 mL of water sample is added to a colorimetric tube containing reagents, and the concentration is read by comparing it with a color chart. There is also a method to read the color development using a portable spectrophotometer. Please feel free to consult us for more information.

What is pool water quality testing? Sampling methods and test items [Basic knowledge]

The standards and the frequency of inspections differ between school pools and public pools. I will explain the locations for water sampling, the preparation of bottles, and the inspection items.

The water in pools is disinfected with chlorine to accommodate many people entering at the same time, and specific items are regularly tested. However, the standards followed differ depending on the type of pool. ■ Are the standards the same for school and public pools? School swimming pools are managed according to the "School Environmental Health Standards" set by the Ministry of Education, Culture, Sports, Science and Technology based on the School Health and Safety Act. For other swimming pools, the Ministry of Health, Labour and Welfare has provided "Hygiene Standards for Swimming Pools" for local governments, which they use as a reference to establish their own regulations. These hygiene standards for swimming pools do not apply to school pools. ■ What are the main testing items and standard values? The main water quality values are common to both standards. 1. Free residual chlorine: 0.4 mg/L or more (1.0 mg/L or less is desirable) 2. pH value: 5.8 or more and 8.6 or less 3. E. coli: Not detectable 4. General bacteria: 200 colonies or fewer per 1 mL 5. Potassium permanganate consumption: 12 mg/L or less 6. Turbidity: 2 degrees or less 7. Total trihalomethanes: 0.2 mg/L or less is desirable Please feel free to consult with us first.

[Case Study] Occurrence of Odor in Factory's Water Supply Pipe

Odor occurrence! Introducing a case where we proposed completely separating the drinking water pipe and the industrial water pipe.

In a factory, there was a section of the water supply pipe where an unusual odor was detected, and it was considered possible that the water supply pipe and the industrial water pipe were connected. Therefore, we investigated the routes of the water supply pipes in the factory and in a separate building to confirm whether they were connected to the industrial water pipe. We also checked the residual chlorine levels in each building. As a result of the investigation, we discovered a connection point between the water supply pipe and the industrial water pipe (image: the blue section is the water supply pipe; the red section is the industrial water pipe). Although valves were installed, if all the valves were opened, the water supply and industrial water would flow into each other's piping. Therefore, we proposed to completely separate the water supply pipe from the industrial water pipe. 【Case Summary】 ■ Issues - Unusual odor detected in the water supply pipe - Connection point between the water supply pipe and the industrial water pipe discovered ■ Solution - Proposed to completely separate the water supply pipe from the industrial water pipe *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Changes in water quality are a red flag for equipment troubles!

We present a case where fluoride was detected in the results of cold and warm water quality testing, and it was found that there was a refrigerant gas leak following equipment inspection.

During the regular inspection of the facility's water management items, an anomaly was detected. The results of the cold and hot water quality tests showed that the pH value decreased from "7.5→7.0→6.5" over a certain period, and further analysis detected fluoride. It was determined that there was a possibility of refrigerant (freon) contamination, and upon inspecting the equipment, it was found that there was a refrigerant gas leak from the copper tube inside the freezer. [Summary] ■ Issues - An anomaly was detected in the facility's water management items. ■ Solutions - Equipment inspection was conducted. - A refrigerant gas leak from the copper tube inside the freezer was identified. *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Pay Attention to "Water" Even in New Buildings!

Introduction of a case where iron exceeding the standard value was detected in drinking water just before the completion of new hospital construction.

This is an introduction to a case where iron exceeding the standard value was detected in drinking water just before the completion of a new hospital construction project. One example of detecting iron is corrosion of steel pipes. However, this is unlikely in a new construction site, so an investigation of the water supply system revealed that there was a mistake in connecting the water supply pipes and the utility water pipes. Additionally, our company has also identified foreign substances using advanced equipment and a rich database. [Overview] ■ Issue - Detection of iron exceeding the standard value in drinking water just before the completion of new construction ■ Solution - Conducted an investigation of the water supply system - Determined that there was a mistake in connecting the water supply pipes and the utility water pipes [Be cautious of such troubles at new construction sites!] ■ Water may stagnate in the pipes for a long time, leading to the possibility of general bacteria and TOC (total organic carbon) exceeding standard values ■ If the water source is well water, components from the soil may leach out, causing iron, manganese, and fungi to exceed standard values.
