municipal secondary treatment

Secondary treatment in the municipal waste water treatment plants.

The secondary treatment is the digestion and solids removal stage of the municipal waste water treatment.

Specifically it is made to remove those particles that prevent a proper functioning of the digestion or take their place when used together with chemical additives (chemical-physical process).


The units included in such range are:

  • Dissolved Air Flotation units (RAF).
  • MBR membrane systems protection (RS3, RS4).
  • Floating grease removal systems (RSK).
