Magnetic Water Treatment Device 'Muzatsu' <Case Study Presentation>

Magnetic Water Treatment Device 'Muzatsu' <Case Study Presentation>

A proposal for cooling tower managers who are fighting with long-term chemical input.

To the engineers who have been fighting for a long time with the long-term, economic, and management operations of cooling towers, are you still forced to use chemical treatments? Regarding the issues of scale, slime, rust, and algae, which are essential for the operation of cooling towers, I speculate that the current specific measures are primarily chemical treatments or maintenance through manpower. Therefore, we have a proposal from Toko. The measures for the 3S problems of scale, slime, and rust in water have already been completed. An effective countermeasure is the utilization of water. This is a strategy based on understanding water pressure, flow, and volume, and there is no risk of failure. Cooling tower engineers, please consider this low-risk, high-return strategy. There will be no charge if results are not achieved. You can use it with confidence. *You can view materials with case studies from the "PDF Download." Please feel free to contact us.

Case Study on Corrosion Prevention Effects of Chilled Water in Air Conditioning Systems [Magnetic Water Treatment Device Vol. 6]

Installed on the supply header outlet side! An example showing a dark brown color compared to the untreated side.

There are two comparison devices for the internal pipe inspection; one utilizes a polarizer, while the other does not. A comparative inspection was conducted under conditions where the polarizer was not used. One polarizer model "PI-50F (2”)” was installed on the discharge side of the supply header for cold and hot water, with partial circulation treatment performed using the polarizer. After treatment, it was evident that old scale and rust had dissolved and flowed out, forming a magnetite anti-corrosion coating inside the pipe, which appeared smoother and had a dark brown color compared to the untreated side. The untreated side showed signs of corrosion and scale adhesion. [Case Study] ■ Installation Date: December 1985 ■ Purpose: Anti-corrosion and anti-scaling for cold and hot water equipment ■ Installation Method: Installed the polarizer model "PI-50F (50A)" on the outlet side of the supply header ■ Treated Water Volume: Treated more than 5% of the total circulating water volume *For more details, please refer to the PDF document or feel free to contact us.

Cooling Water (Chiller Water) Molding Machine Mold Case Study [Magnetic Water Treatment Device Vol. 2]

Cooling water volume increased by 16%! Red rust has been completely removed and changed to black rust.

Tests were conducted in the cooling passages of plastic molds with the aim of removing blockages caused by rust and scale using a polarizer, thereby restoring cooling effectiveness. Additionally, we confirmed whether the removal of red rust from the cooling passages and its reduction to black rust (magnetite) would lead to the formation of an anti-corrosion coating. As a result, when the rust that had dissolved into the water tank was collected and a magnet was applied, the rust was attracted to the magnet, indicating that it had transformed into magnetite. [Test Details] ■ Purpose - To remove blockages caused by rust and scale in the cooling passages of plastic molds using a polarizer, thereby restoring cooling effectiveness (increasing cooling water flow rate). - To confirm whether the removal of red rust from the cooling passages and its reduction to black rust would lead to the formation of an anti-corrosion coating. ■ Location: SK Corporation Headquarters (Gifu Prefecture) ■ Duration: January 21, 1992 - May 30, 1992 (24-hour continuous bench test operation) *For more details, please refer to the PDF document or feel free to contact us.

About the cause of red water (300 households) [Magnetic water treatment device Vol. 2]

About the cause of red water (300 households) [Magnetic water treatment device Vol. 2]

We will introduce examples of conducting water main extraction in various housing complexes and investigating corrosion within the pipes!

Since the 1970s, as a measure against red water in buildings constructed after that period, the Ministry of Construction has guided the increased use of PVC-lined pipes over white gas pipes (galvanized steel pipes). Furthermore, from the 1980s to the present day (2002), many buildings, apartments, and general residences have experienced occurrences of red water every morning. As a result, in various housing complexes, investigations were conducted on the corrosion of the water supply pipes by removing them. The findings revealed that most of the corrosion inside the pipes was caused by the potential difference between dissimilar metals at the valves and pipe joints, as well as damage to the PVC lining seals. It was determined that the dissolved oxygen in the water reacts electrochemically with the metals through the water. [Causes] ■ Most of the corrosion inside the pipes is due to the potential difference between dissimilar metals at the valves and pipe joints, and damage to the PVC lining seals. ■ The dissolved oxygen in the water reacts electrochemically with the metals through the water. *For more details, please refer to the PDF document or feel free to contact us.

Red Water Countermeasures (Hotel Hot Water Supply) [Magnetic Water Treatment Device Vol. 9]

Installed with a partial bypass method on return pipe 65A! Introduction of a case where red rust in the boiler turned into black rust and red water stopped.

There was a complaint that red water was coming out of the hot water faucet in the guest rooms within three years of the hotel's completion, and various measures were taken, but the issue was not resolved at all. As a result, a Polar magnetic water treatment device "Model PI-25F" (3-point set) was installed in a partial bypass configuration on the return pipe 65A, treating about 20% of the circulating water volume. As a result, it was confirmed that the red rust in the boiler had turned into black rust, and the red water had stopped. [Case Study] ■ Issues - Despite the piping being made of stainless steel and plastic, red water occurred. - The cause of the red water was corrosion due to an abnormal oxidation reaction of dissolved oxygen (DO) in the water inside the steel hot water heater. ■ Measures - A Polar magnetic water treatment device "Model PI-25F" (3-point set) was installed in a partial bypass configuration on the return pipe 65A. *For more details, please refer to the PDF document or feel free to contact us.
