BIO-SIL WWA/5-RTU is an active emulsion of silica filled Polydimethylsiloxane which is specifically formulated for the control of foam in waste water systems and holding ponds. BIO-SIL WWA/5-RTU is a low viscosity ready to use antifoam that can be dosed directly into the water source for effective foam control.

Starting Guide.

As a processing aid: For maximum performance, BIO-SIL WWA/5-RTU can be administered directly into the foaming system with a metered pump. BIO-SIL WWA/5-RTU is efficiently dispersed with minimum agitation.

For end use: BIO-SIL WWA/5-RTU does not require pre-dilution and the emulsions can be added directly from the original shipped container to the foaming system. Concentrations in the range of 0.1 to 0.2% have been determined as a good starting point.

Please Note.

  •  Testing before formulating should be carried out as systems vary.

  • Material Safety Data Sheets are available upon request.

  • The shelf life period without testing is 12 months from date of manufacture, if stored in the original unopened container at 4°C to 27°C.

  • Mild agitation should be carried out if stored as the nature of any emulsion is to separate without agitation over extended periods of storage.
