Electrophysical precipitation

Electrophysical precipitation dissolves ions in water on a sacrificial anode made of iron or aluminium. This forms hydroxides and facilitates the separation of extremely small solid particles, which are often found in stable emulsions and suspensions, by means of adsorption, precipitation or flocculation.

At the same time, water is cleaved on the surface of the electrodes into highly-reactive radicals which create numerous secondary reactions with water components leading to a decrease in chemical oxygen demand (COD).

These oxidative processes can also be used for disinfecting.
