Solution

The N-SEP 438 chemicals provide excellent coagulation, flocculation for separation of SS in the dissolved air flotation unit. The sludge produced contains higher organic carbon fraction compared to sludge produced from adding metal salts or lime and is therefore ideal for their biogas production.

Solution

The N-SEP products works with sewage, industrial and food waste water. It simplifies operations, reduce investment cost and increases separation degree (suspended solids) in new and existing treatment pants; Sedimentation, Flotation or Filtration.
