Physical-chemical purification plants allow water pollutants – often not biodegradable – removal using chemical reagents. These additives react with pollutants and make them insoluble so that they are broken down by neutralization, coagulation/flocculation, precipitation.
Chemical-physical plant projects are studied case by case and based on in relation to the peculiarities of the water to be treated, the discharge parameters and customer demand.
The chemical-physical process phases are basically:
- Insolubility of metal salts
- Coagulation – flocculation
- Final treatments
The water to be treated is stored in a homogenization tank placed at the head of the plant to feed the purification process with permanent parameters water.
