Effect of Open Cooling Towers on Algae Suppression [Magnetic Water Treatment Device Vol. 14]

Effect of Open Cooling Towers on Algae Suppression [Magnetic Water Treatment Device Vol. 14]

A comparative test was conducted at a certain public facility in Tokyo! We will introduce a case where water clarity improved through polar treatment.

Two identical cooling towers are arranged in parallel using the same source water, and both cooling towers were cleaned in the same manner before entering the test. One of the cooling towers was equipped with the Polar magnetic water treatment device "PI-40F." The other continued to operate as usual with automatic blowdown using an algae growth inhibitor. The side using the inhibitor showed a significant presence of algae throughout, with a lot of foaming in the water, while the side using the Polar device showed no algae growth at all, and the water clarity improved compared to before. [Test Details] - Two identical cooling towers are arranged in parallel, using the same source water. - Both cooling towers were cleaned in the same manner before the test. - One of the cooling towers was equipped with the Polar magnetic water treatment device "PI-40F." - The chemical treatment side continued operation with automatic blowdown using an algae growth inhibitor. *For more details, please refer to the PDF document or feel free to contact us.*

Examples of Softening and Dissolution of Cooling Water System Scale [Magnetic Water Treatment Device Vol. 3]

Examples of Softening and Dissolution of Cooling Water System Scale [Magnetic Water Treatment Device Vol. 3]

Comparison before and after use (2.5 months)! The softening and dissolution of scale was confirmed.

Water treated with magnetic processing using a polarizer causes softening and dissolution of scale. A polarizer model "PI-15(15A)" was installed in the test equipment to investigate the softening and dissolution outflow of scale in the test pipe. Comparing before the use of the polarizer and 2.5 months after its use, it was found that softening and dissolution of the scale occurred. It is considered that it may take a considerable amount of time to remove scale solely with the polarizer, so while the primary purpose is to prevent scale adhesion, it is believed that it does not have the rapid effectiveness of chemical cleaning for removing adhered scale, but it can prevent scale buildup inside the pipes. [Test Overview] ■ Provider: Environmental Frontier Co., Ltd. (Shizuoka City) ■ Test Period: June 1, 1984, to August 15, 1984 (approximately 2.5 months) ■ Purpose: Does water treated with magnetic processing using a polarizer cause softening and dissolution of scale? ■ Method: A polarizer model "PI-15(15A)" was installed in the test equipment to investigate the softening and dissolution outflow of scale in the test pipe. *For more details, please refer to the PDF document or feel free to contact us.

Red Water Countermeasures (Hotel Hot Water) [Magnetic Water Treatment Device Vol. 12]

Red Water Countermeasures (Hotel Hot Water) [Magnetic Water Treatment Device Vol. 12]

We will introduce a case where the red water completely stopped, the water became transparent, and the troubles were resolved!

The effectiveness of Polar as a countermeasure against hot water red water was confirmed. In large buildings and hotels, after more than 10 years, the dissolved oxygen, chlorine ions, and pH in the water cause corrosion to progress on the inner surface of the pipelines, resulting in red water due to rust in the hot water and bath, which becomes a significant operational issue. In response to such troubles, Polar significantly suppresses the progression of corrosion without the need for chemical injection, resolving the red water issue. The facts regarding this matter were evaluated by a lining contractor in the residential newspaper "Amenity." [Case Study] ■ Purpose: Confirmation of the effectiveness of Polar as a countermeasure against hot water red water. ■ Installation: One unit of Polar model "PI-40F" was installed in a bypass manner on the main pipe to treat 50% of the hot water circulation volume magnetically (installed on June 5, 1987). *For more details, please refer to the PDF document or feel free to contact us.

Case study on the removal of red rust from cooling water (chiller water) [Magnetic Water Treatment Device Vol. 1]

Case study on the removal of red rust from cooling water (chiller water) [Magnetic Water Treatment Device Vol. 1]

Conducting a test to confirm the effectiveness of rust removal! After the test, we will introduce cases where the rust was beautifully removed.

We would like to introduce the test conducted by our company to confirm the effectiveness of Polar in removing red rust. The water tank used was made from a drum that had been utilized during fire training, and it was quite rusty both inside and out. The purpose of the test was to observe how the rust on the inside and bottom, which came into contact with Polar water, would change. During the test, the rust inside the tank (drum) caused the water to become red and murky, making the bottom invisible. However, after the test, the rust on the inner walls and bottom that had come into contact with Polar water was completely removed. It should be noted that the upper part of the inner wall, about 10 cm high, which did not come into contact with Polar water, remained unchanged from before the test. [Test Overview] ■ Duration: February 23, 1989 - March 16, 1989 ■ Location: Underground boiler room of a certain automobile dealer headquarters in Nagano City ■ Purpose - To remove the red rust (Fe203) generated inside the sample pipe by Polar and to see if it can be reduced to black rust (Fe304). *For more details, please refer to the PDF document or feel free to contact us.

Case Study on Scale Prevention in Closed Cooling Towers [Magnetic Water Treatment Device Vol. 6]

We will introduce a case where it was confirmed that there was no scale adhesion and successfully saved on water costs!

On October 24, 2000, a polar type "PI-25CF" was installed on the spray pipe of the cooling tower using a partial bypass method, and automatic blow management was conducted without chemicals at the conventional electrical conductivity of 60 ms/m. On November 22, 2000, one month after using the polar system, a check was conducted for scale deposition at the heat exchange section of the cooling tower, and no scale was found, confirming the effectiveness of the polar system. At 3.5 months of using the polar system, an extreme experiment was conducted by further concentrating the electrical conductivity to 120 ms/m to save on water supply, and it was confirmed that there was no scale deposition, successfully achieving savings on water costs. [Issues and Measures] - The supply water (well water) had a pH of 6.7, electrical conductivity of 30 ms/m, silica of 56 mg/L, M-alkali of 76 mg/L, and calcium of 31 mg/L, making water quality management very challenging. - The model "PI-25CF" was installed, which includes a magnet strainer, the polar main unit, and a flow meter. *For more details, please refer to the PDF document or feel free to contact us.*
