Silicone defoamer for wastewater treatment is a special foam control additive developed to solve foam problems during industrial wastewater treatment. It is mainly compounded of modified silicone, dispersant and carrier components. It features stable chemical properties and does not affect biochemical bacteria activity.

It can handle foam issues generated in different wastewater treatment sections. It delivers fast defoaming and long-lasting foam suppression performance. It will not trigger adverse chemical reactions with flocculants, pH regulators and other water treatment chemicals. It will not interfere with sludge precipitation and biochemical treatment process. Therefore, it is widely used in sewage treatment systems of various industries.

Main application scenarios of silicone defoamer for wastewater treatment

• Silicone defoamer for wastewater treatment is suitable for: chemical plant wastewater, textile printing & dyeing wastewater, paper mill wastewater, food processing wastewater, circulating water system, aeration tank, sedimentation tank, sewage aerobic fermentation and wastewater sludge stripping process.

• There are two key wastewater treatment stages where silicone defoamer works: aeration biochemical stage and sludge concentration stage.

• During the aeration biochemical stage, continuous air blowing and metabolism of microorganisms produce large amounts of persistent foam. Excessive foam will overflow from the tank, cause loss of activated sludge and reduce treatment efficiency. The silicone defoamer quickly breaks the accumulated foam on the water surface. It disperses rapidly in the sewage and eliminates foam without inhibiting the activity of aerobic bacteria.

• While in the sludge concentration stage, stirring and sludge decomposition generate micro foam. Foam will slow down sludge settlement and make the effluent turbid. The defoamer penetrates into the foam layer and suppresses new foam generation. It helps solid-liquid separation, ensures clear outlet water quality and stabilizes the whole wastewater treatment operation.

Key features of silicone defoamer for wastewater treatment

• Good water dispersibility, easy dilution and addition on site

• Adaptable to wide pH and temperature range of sewage systems

• Fast defoaming speed and durable foam inhibition effect

• Low addition dosage, cost-effective for large-volume sewage

• Does not poison activated sludge or disturb biochemical system

• Good compatibility with common water treatment chemicals
