Physical Chemical

A physico-chemical treatment is often a combination of pH adjustment, coagulation and flocculation.

The coagulant is often FeCl3 (Ferric Cloride) or an aluminum salt and as a flocculant a cationic or anionic polymer is used.

For the mixing of these chemicals in the waste water a stirred flocculator or pipe-flocculator can be used.

Aaqua offers in its product range the necessary equipment ranging from measuring equipment, metering pumps, polymer make up station, flocculants etc.

This treatment is often used:

  • prior to a flotation unit
  • prior to a sedimentation unit
