Silicone-based defoamers play a key role in wastewater treatment processes. They function by reducing foam levels, thus helping to maintain the efficacy and efficiency of the treatment process.

Low Surface Tension: These defoamers possess low surface tension, which is critical to their action. This characteristic allows them to spread rapidly over the surface when applied to a foaming solution.

Action on Foam Bubbles: Once spread over the foam, silicone-based defoamers act on the surface of the foam bubbles. They rupture the wall of the foam bubbles, causing them to break apart and release the gas trapped inside.

Prevention of Foam Formation: By reducing the surface tension of the liquid, these defoamers also help to prevent the formation of new foam bubbles. The reduced surface tension hampers the locking of air, thus preventing foam from forming.
