Silicone-based defoamers are known to masterfully tackle excessive foaming. Harnessing their innate characteristics, they adjust the surface tension in foam bubbles, effectively defoaming the wastewater treatment process. Let’s delve into how they accomplish this feat.

Inherent Low Surface Tension: Silicone-based defoamers inherently showcase lesser surface tension compared to aqueous solutions. That innate property gives them an edge in their utility.

Spreading Across the Foaming Surface: As soon as they are introduced to the foaming solution, silicone-based defoamers, leveraging their low surface tension, spread quickly over the solution’s surface. This rapid spreading allows them to cover a larger surface area in a shorter period of time, ensuring maximum effectiveness.

Interference with Bubble Surface: The defoamers then interact with the surface of the foam bubbles. They reduce the surface tension of the liquid-to-air interface, destabilizing the structure that’s maintaining the bubble.

Destabilizing Bubble Integrity: By lowering surface tension, these defoamers disrupt the equilibrium that maintains the bubble’s structure, leading to the bubble’s collapse.
