Municipal waste water

Primary flocculation in drinking water treatment plants


Many human activities lead to the production of waste effluents, the so-called waste water, which requires the removal of contaminants, i.e. all those organic and inorganic substances and pollutants that must be eliminated before effluents are discharged into the environment – producing disastrous effects.

PRO-DO-MIX® agitators are widely used in every phase of the water treatment process: thanks to their performance levels, they are not only a safe and reliable solution for water collection and treatment, but also efficient energy saving, and at the same time, highly environment-friendly tools.

Moreover, thanks to the collaboration with the fluid mixing giantNOV/Chemineer, PRO-DO-MIX® can offer products capable of meeting every production need, allowing Kenics static mixer to be integrated in systems for mixing chemicals using large volumes of water.
