Our approach

We take a thorough approach to finding the most effective treatment.

  1. Sample

    We take a representative sample of your wastewater.

  2. Analysis

    We analyse the required parameters before treatment and in the resulting filtrate.

  3. Advice or trial

    This establishes treatment performance and chemical requirements. We would be pleased to visit and discuss your situation.

  4. Implementation

    In your existing operation or in a new system we supply.

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

  1. Adding a coagulant neutralises negatively charged particles. They no longer repel one another and aggregate, enabling sedimentation or flotation and subsequent removal.

  2. 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.

  3. A liquid or gas is taken into a solid, enabling contaminants to be removed from the water.
