• Application cases of water treatment defoamer

Foam problems encountered by customers:

1. The excessive foam caused the Environmental Protection Agency to fail to meet the testing standards and could not be discharged directly, delaying the work process.
2. Too much foam overflows from the surface, causing serious pollution to the external environment.
3. Too much foam makes it unsightly. There is too much foam during aeration or oxygen supply during biological water treatment, which affects the progress of water treatment or overflow, and affects the activated mud and bacteria.
4. Excessive foam in circulating water affects secondary utilization, production progress, and more seriously, directly affects the products produced.
5. Defoaming agents are harmful to biological bacteria, have an impact on the MBR system, damage the percolation membrane, and worry about clogging the ultrafiltration membrane.
6. Too much foam accumulation affects space utilization.
7. Worried about the high cost and inconvenient operation.

• The principle of water treatment defoamer:

Characteristics of the water treatment industry: In the modern era, there are many factories that urgently need to treat sewage, such as: paper mill sewage, numerous chemical plant sewage, pharmaceutical factory sewage, other processing plant sewage, breeding plant sewage, and even hospitals, residential areas, and urban sewage. All kinds of wastewater should be properly treated before being discharged into rivers. When treating water quality, a large amount of foam needs to be added to the water treatment defoamer to fundamentally reduce the foam.Water treatment defoamer E-193 developed by Zilibon Chemical is a defoaming agent specially developed for various water treatment systems. The characteristics are: fast defoaming speed, long foam suppression time, high efficiency, low dosage, no corrosion, no impact on the progress of water treatment, water quality index detection and discharge, easy to disperse in water, and good compatibility with liquid products. Tolerant, not easy to break emulsion and oil.

Biochemical treatment uses microorganisms including bacteria, fungi, algae and protozoa to oxidize and decompose harmful substances in water into harmless substances. These microorganisms can survive in water containing poisons and use these poisons as nutrients to reproduce, thus converting poisons into new substances that are harmless to humans. An important step in biochemical treatment is aeration, that is, through mechanical stirring and air blowing, the sewage is fully contacted with the air to maintain sufficient dissolved oxygen in the water and provide suitable conditions for microbial activities. However, foam will be generated during aeration, and a thick foam layer will affect dissolved oxygen, reduce the efficiency of the aeration device, and extend the treatment cycle. Water treatment defoamer - Tests have proven that if the added defoaming agent is increased by 10 times, it will have no effect on microorganisms and will have no effect on the COD (chemical oxygen demand) of sewage.

Water treatment defoaming agent E-193: paper mill sewage, numerous chemical plant sewage, pharmaceutical factory sewage, other processing plant sewage, breeding plant sewage, and even hospitals, residential areas, urban sewage, various wastewater defoaming treatments, various types Circulating sewage treatment, various types of circulating industrial sewage, circulating wastewater treatment in various industries, all medium and normal temperature, alkaline system water treatment and defoaming, etc.

Characteristics: fast defoaming speed, long foam suppression time, high efficiency, low dosage, no corrosion, no impact on the progress of water treatment, water quality index detection and discharge, easy to disperse in water, and well compatible with liquid products. Not easy to break the emulsion and bleach the oil.
