In industrial wastewater treatment, rampant foam is a common but stubborn problem. Excessive foam reduces treatment efficiency, increases energy consumption, and can even cause unexpected equipment shutdowns. Traditional defoaming methods often provide only short-lived effects or introduce new pollutants.
Chemi Tech focuses on the R&D and production of high-performance defoamers and provides customized solutions for different wastewater characteristics. Our defoamers use special modified-polysiloxane composite technology to rapidly break surface foam and inhibit re-foaming, while withstanding harsh conditions such as high temperature, high alkalinity, and high salinity.
Typical application case: an electronic-component manufacturer generated large amounts of stubborn foam in its coating and cleaning process, and its original defoamer required frequent dosing with unstable results. After on-site diagnosis by the Chemi Tech technical team, the KM-1240 series defoamer was recommended. Through a small-scale test to confirm suitability, followed by optimization of the dosing point and dosage (50–200 ppm per ton of water), the foam subsided within five minutes, average daily consumption dropped by 40%, and the biochemical system was not affected.
Solution steps:
1. Foam sample analysis: laboratory testing to identify the type of foaming substances and the system environment.
2. Product selection: provide three compatible samples for small-scale comparison.
3. On-site verification: trial dosing at the inlet section of the equalization tank or aeration tank.
4. Solution optimization: adjust concentration and dosing method based on feedback.
5. Long-term tracking: regular follow-up visits to ensure stability.
Chemi Tech defoamers have been applied in wastewater treatment systems for electroplating, printing and dyeing, and papermaking, helping customers achieve stable, compliant treatment results.
