Trattamento acque Impianti trattamento acque industriali
Completion and upgrading of the wastewater treatment plant of Rozzano (Italy)
The conventional plant, based on activated sludge, was built in several steps between the 1970s and 1986 to serve 75,000 Equivalent In-habitants, with a 50% share of industrial effluents.
If, on the one hand population growth in the past 20 years made it necessary to upgrade the facility for 95,000 Equivalent Inhabitants, on the other hand the decree 152/99 also requires the upgrading of the treatment cycle to comply with the new stricter limits.
The project includes:
- doubling of the sand catching/separation phase;
- enhancement of the activated sludge biological treatment with the adoption of a moving bed adhered biomass treatment and modification of the aeration system;
- new final disinfection stage;
- new final filtration on textile.
