Industrial circulating water is also called circulating cooling water, which is mainly used in cooling water systems. my country's industrial cooling water accounts for more than 90% of the total water consumption. After the circulating water has been recycled for many times, a large amount of auxiliaries are put into it, which leads to excessively high surface activity in the water and a large amount of foam. So what should I do if industrial circulating water encounters bubbles? We can add circulating water defoamer to control the foam production. The defoamer will not cause any adverse effects on the water quality. It is a good solution.

Reasons for bubbling of circulating water
1. Surfactant foam
The water in the pool has been recycled for many times, and a large amount of additives has been invested, resulting in excessively high surface activity in the water and a large amount of foam.
2. Denitrification foam
When the activated sludge treatment system is operated at low load, denitrification will occur in the sedimentation tank or the place where aeration is insufficient to generate nitrogen. The release of nitrogen will reduce the density of sludge to a certain extent and drive part of the sludge to float up. Bubble phenomenon.
3. The system is abnormal
Caused by the increase in the content of microorganisms and bacteria, the organic matter decomposes to produce foam, and then the added fungicide causes the death of a large number of microorganisms, and produces slime and foam
The harm of circulating water foam
1. Circulating water bubbles will cause the Environmental Protection Agency to detect non-compliance, fail to discharge, and slow down the progress of work
2. Too much foam overflows from the surface, causing serious pollution of the external environment
3. Excessive foam in circulating water affects secondary utilization, production schedule, and more seriously directly affects the products produced
4. There are too many bubbles during aeration or oxygen supply in biological water treatment, which affects the progress or overflow of water treatment, and affects the activated mud and bacteria
5. Excessive foam in the circulating water will overflow from the pool and cause pollution to the surrounding environment.

The Nanhui defoamer manufacturer has developed and designed a high-concentration defoamer for the circulating water treatment defoamer that is prone to a large amount of foam in the circulating water system. It is very convenient to use, it can be directly dripped or diluted and sprayed.
Advantages of Nanhui circulating water treatment defoamer
1. Factory direct sales, cost-effective, free samples;
2. Nanhui defoamer has a professional team that provides one-to-one foam solutions;
3. Water treatment defoamer has good dispersibility, fast defoaming and defoaming, and low dosage;
4. The defoaming agent has the properties of high temperature resistance, acid and alkali resistance, and can be used for defoaming in various water quality. It can continue to defoam and inhibit foam. It will not react with other chemicals in the sewage and will not affect the water treatment process.
