[Case] Equipment water quality inspection: The water quality is fine, but the cooling tower has stopped abnormally!

[Case] Equipment water quality inspection: The water quality is fine, but the cooling tower has stopped abnormally!

We propose a comprehensive maintenance method that includes water quality testing, equipment cleaning, and water quality management.

Water quality testing for equipment water is often conducted to investigate the causes when issues arise in air conditioning systems and other equipment. Based on extensive experience and a accumulated database, testing items are selected according to the situation of the trouble, and the causes are pursued based on the results. Additionally, when the cause is identified through water quality testing, measures such as pipe cleaning and chemical treatment are considered, proposing a total maintenance approach of 【water quality testing → equipment cleaning → water quality management】. ■ Examples of Equipment Water Quality Testing CASE 1: Water Quality Change (P22) 【Changes in water quality are a red flag for equipment troubles!】 CASE 2: Abnormal Shutdown of Cooling Tower (P22) 【The water quality is fine, but the cooling tower has an abnormal shutdown!】 CASE 3: Hole in the Condenser of the Freezer (P22) 【Strange? There’s a hole in the condenser of the freezer!】 *Japan Water Treatment Industry is a registered organization under Article 20 of the Water Supply Act, registered by the Ministry of Health, Labour and Welfare.

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

[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!

[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!

[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.

Water quality analysis for dialysis water

Water quality analysis for dialysis water

Testing of chemical contaminants: 12 items of dialysis water quality standards.

The international standard for the management of dialysis water (ISO 13959) specifies 22 items related to chemical contaminants as management items. In Japan, the Japan Society for Dialysis Therapy and the Japan Association of Clinical Engineers have presented the "Dialysate Water Quality Standards" as criteria for the management of dialysis water. According to the Dialysate Water Quality Standards, 12 out of the 22 chemical contaminants are designated as management targets, and they must be maintained below the management standard values (maximum concentrations) under the supervision of the Dialysis Equipment Safety Management Committee.
