Physicochemical wastewater treatment
Additives release contaminants so that they can be removed. Treatment can include:
Click a step and see what happens to the water
-
Adding a coagulant neutralises negatively charged particles. They no longer repel one another and aggregate, enabling sedimentation or flotation and subsequent removal.
-
A flocculant or polymer binds free particles into larger flocs. Increased weight accelerates settling. Alternatively, added air bubbles attach to the flocs and make them float.
-
A liquid or gas is taken into a solid, enabling contaminants to be removed from the water.
Products
Appropriate chemicals are essential for physicochemical wastewater treatment and effective plant operation.
