Closed cooling towers in the cooling tower industry is also sold by wind and water, but closed cooling towers often show scale, corrosion accumulation, rust, bacteria cause a lot of pollution, which is also a topic we often discuss, then why closed cooling towers will show this situation, the following to explain.

Closed cooling tower is exposed to air in daily use, and there are a lot of suspended matter, dust and impurities in the air will be accumulated in the cooling tower from time to time, so the closed cooling tower will show dirt accumulation. There will also be a lot of biological algal mud in the closed cooling water system, constituting a blocking phenomenon.

In winter, closed cooling towers rarely need to be used. While a lot of water will accumulate in the closed cooling tower, the water in the closed cooling tower will form a certain corrosion on the inside of the closed cooling tower. After a long time, the corrosion materials will accumulate, causing some of the corrosion situation is very severe.

The circulating water of the closed cooling tower contains inorganic salts, organic matter and microorganisms. In some seasons, the water temperature can reach more than 35℃. If the closed cooling water is used for a long time without conversion or water to make up for the shortage, and if the closed cooling water is not cleaned and disinfected for a long time, many bacteria will grow. In the cooling water of the closed cooling tower, many multiply and form microbial aerosols, which partially float directly into the air around the closed cooling tower, so that the surrounding 800 meters will be affected. Therefore, urban closed cooling towers are a primary source of urban pollution.

The pollution of closed cooling towers needs to be protected and optimized from raw materials to finished products.
