Wastewater treatment is a set of measures to remove impurities contained in municipal and industrial wastewater.

 

The purification process can be divided into the following stages:

  • mechanical;
  • physical-chemistry;
  • biological.

Mechanical treatment of wastewater is a preparatory stage before a thorough cleaning of drains. Mechanical treatment objective is to extract from water suspended insoluble solids, fibers and coarse impurities.

 

The following equipment is recommended for use for mechanical cleaning:

  • drum screen;
  • belt filters.

 

Physico- chemical treatment is removal of fine particles and dissolved inorganic impurities, the destruction of organic and poorly oxidizable substances.

 

For physical-chemical treatment it is recommended to use the following equipment:

  • pressure flotators;
  • lamella clarifiers.
