Silicone Defoamer for Biological Wastewater Treatment Antifoam Agent for Aeration Tank Foam Control
Product Introduction
Silicone Defoamer for Biological Wastewater Treatment is a high performance antifoam agent formulated to control foam in aeration systems and biological treatment processes. Based on a water based polydimethylsiloxane emulsion, it delivers rapid defoaming and long lasting foam suppression without disrupting system balance.
Foam formation in biological systems is commonly caused by surfactants, organic loading and microbial activity. Excessive foam can lead to overflow, reduced oxygen transfer and operational instability. This product is designed to solve these issues effectively.

Key Advantages in Biological Systems
Effective Foam Control in Aeration Tanks
The defoamer quickly breaks foam on the surface of aeration tanks and prevents excessive foam accumulation, ensuring stable operation.
Compatible with Activated Sludge Systems
At recommended dosage levels, it does not negatively affect microorganisms or biological activity, making it safe for long term use.
Improved Oxygen Transfer Efficiency
By reducing foam layers, it helps improve oxygen transfer and enhances treatment performance in biological processes.
Stable Performance in Continuous Operation
Maintains consistent defoaming efficiency in dynamic and continuously operating wastewater treatment plants.
Low Dosage and High Efficiency
Typical dosage between 10 and 100 ppm provides strong foam control while keeping operational costs low.
Technical Specifications
Application in Wastewater Treatment Plants
This defoamer is widely used in municipal and industrial wastewater treatment systems.
In aeration tanks it controls foam generated by biological activity and surfactants, preventing overflow and maintaining stable operation.
In activated sludge systems it supports efficient treatment by reducing foam interference and improving oxygen transfer.
It is also suitable for secondary treatment units and sludge handling processes where foam may impact system performance.

Packaging and Storage
Available in 200 liter drums and 1000 liter IBC containers. Store in closed containers and avoid extreme temperatures to maintain product stability.
