How do silicone antifoams contribute to cleaner water treatment process?

Civic and industrial companies, environmental service companies and wastewater treatment plants all use that processes create foam, which we can help you to control.

Elkem Silicones has developed its Silcolapse™ range of foam control agents to deal with this issue at all stages of these processes. These emulsions are materials of choice: they contain non-toxic, chemically inert silicones that are environmentally friendly. They are easy to use and provide durable efficiency to enhance your process reliability and reduce your maintenance costs. Another advantage is that they are efficient in much smaller doses than organic antifoaming solutions.

Benefits of Silcolapse™​ foam control agents include:

  • Durable foam control at all stages of the cleaning process
  • High efficiency at very low dosage
  • Enhanced process reliability for the water treatment plant
  • Easy to handle due to excellent dispersion in aqueous media
  • Easy to use in a broad variety of industrial media and over a wide range of pH
