With the tightening of environmental policies, the demand for efficient defoamers in the sewage treatment industry is increasing day by day. In the third quarter of 2025, many sewage treatment enterprises reported that the foam control effect was significantly improved after the new silicone defoamer was adopted, the dosage of agent was reduced by 50%, and the stability of effluent water quality was enhanced. According to the technology provider, the defoamer uses modified polysiloxane as the core component and achieves a balance between rapid foam breaking and persistent foam suppression through molecular structure design. Its biodegradation rate exceeds 95%, which is in line with the trend of green chemical development. At present, the product has been applied in sewage treatment plants in more than 20 provincial-level administrative regions across the country.
