Wastewater treatment plants AT 300 - AT 2000 oval MAXI with VFL® technology

Wastewater treatment plants AT 300 to AT 2000 oval MAXI

Wastewater treatment plants AT 300 to AT 2000 oval MAXI are designed for centralized wastewater treatment solutions in municipalities up to 2000 PE. Capacitively suitable for sewage sources from 45 to 300 m3 / day. They are supplied as a complete technological line supplemented by a pumping station with mechanical pre-treatment, homogenization tank, sludge management and a complete technical infrastructure. The parallel connection of individual biological reactors ensures the possibility of staged construction.
 
They are used for the treatment of sewage and municipal wastewater from municipalities up to 2000 PE.
 
Treated wastewater, after biological treatment or tertiary treatment, is discharged into surface waters.

Installation of WWTP type AT 300 to AT 2000 oval MAXI
 
They are installed in the excavation as recessed tanks on a reinforced concrete foundation slab about 400 mm thick so that the upper edge of the inspection entrances (chimneys) protrudes about 50 mm above the prepared terrain.
The pumping station, the buffer homogenization tank and the sludge tank are installed in the same way. Above these tanks there is a container building with facilities for the operator and also rooms for mechanical pre-treatment, blowers and sludge management, which form the complete technical infrastructure of the treatment plant.

The guaranteed and commonly achieved parameters from the outpour of the wastewater treatment plants are shown in the table below. The quality of purified water corresponds with the Directive No. 269/2010 requirements in the Collections of Laws according to the Government of the Slovak republic for discharging the water into the ground or on the surface (51-2000 EO).

Values after biological treatment:

Parameter Commonly  achieved  values Guaranteed values
CODCr 35 mg/l 135 mg/l
BOD5 10 mg/l 30 mg/l
SS 10 mg/l 30 mg/l
N-NH4 2 mg/l ---
Ntot 15 mg/l ---
