Aeration Tank Defoamer Silicone Antifoam for Activated Sludge and Biological Wastewater Treatment
Product Introduction
BWF160 is a silicone based antifoam agent formulated as a dimethyl polysiloxane emulsion, designed for effective foam control in biological wastewater treatment systems. It performs efficiently in aeration tanks and activated sludge processes where foam is commonly generated by microorganisms and surfactants.
Foam accumulation in these systems can lead to overflow, reduced oxygen transfer and unstable operation. BWF160 provides a reliable solution by quickly eliminating foam and maintaining system balance.
Key Benefits in Aeration Systems
Specialized for Aeration Tank Foam Control
BWF160 effectively controls foam on the surface of aeration tanks, preventing overflow and maintaining safe operation.
Compatible with Activated Sludge Processes
At recommended dosage levels, it does not interfere with microbial activity, making it suitable for long term use in biological treatment.
Improved Oxygen Transfer Efficiency
By reducing foam layers, it enhances oxygen transfer efficiency and supports better biological performance.
Rapid Dispersion in Water
As a water based emulsion, it disperses quickly in wastewater systems and provides immediate defoaming effect.
Stable and Continuous Performance
With viscosity ≤1000 cPs and fine particle size below 100 microns, it ensures consistent performance in continuous treatment systems.
