The resulting sludge contains less chemically bound water and can be more easily dewatered. Polymeric coagulants do not affect pH. Therefore, the need for supplemental alkalinity, such as lime, caustic, or soda ash, is reduced or eliminated. Polymeric coagulants do not add to the total dissolved solids concentration. For example, 1 ppm of alum ...

Sludge Dewatering Products from Manufacturer Beckart Environmental. When it comes to sludge dewatering, effectiveness is important.
