Belgorod Dairy, Parmalat, Russia, 2017
The Wastewater Treatment Plant ensures the treatment of industrial effluent (wastewater, WW) produced at Parmalat JSC “Belgorod Dairy Factory”. There had been no WWTP before we have built the new one. The dairy factory discharged WW into the local urban sewer system without any purification. Nowadays, treated wastewater is discharged into the local sewer system. Despite the fact the treated WW does not flow to a watercourse the limits are quite strict but there is no problem to comply with them though.
