Recycling & Water Treatment

About

PennWhite’s Foamdoctor ® suppresses the foam generated during many recycling and water treatment processes, while Silstrip ® safely removes silicone insulation from recyclable electrical components.

PennWhite’s Foamdoctor ® range eliminates unwanted foam created in secondary treatment tanks during treatment of waste water and effluent, improving plant efficiency and hygiene performance.
