Oval wastewater treatment plants - AT30 to AT250 oval
AT 30 to AT 250 oval wastewater treatment plants were invented to purify sewage water for blocks of houses, small villages, parts of a village, accommodation properties, restaurants, recreational properties, manufacturing factories, industrial parks. After preliminary purification of industrial wastewater with organic pollution the plants serve as biological treatment for meat processing factories, dairy factories and slaughterhouses, wineries, etc. Furthermore the purified water can either discharge into the surface or underground water, respectively it can be reused for irrigation.
Aquatec VFL oval wastewater treatment plant includes:
- Biological reactor of wastewater treatment unit.
- Air pump tank intergrated in the cover of the WWTP.
- Control unit AQC Basic with GSM remote control.
- Air pump or Air pumps regarding the type of the WWTP.
- 230V service plug.
The wastewater treatment systems comprised of the biological reactors from AT30 oval to AT250 oval can be gradually expanded by installing several units in parallel.

Vertical Flow Labyrinth – VFL®
Wastewater treatment plants of the AT 30 oval to AT 250 oval series are supplied as a standard or as a complete technological line consisting of one all-plastic biological reactor with the possibility of expansion with a pumping station with mechanical pre-treatment and a sludge tank, respectively.
The technology Vertical Flow Labyrinth – VFL®, used in the biological reactor, is protected internationally by patent. The treatment technology ensures the high quality of purified water, low investment and operation costs.
The guaranteed and commonly achieved parameters from the outpour of the wastewater treatment plants are shown in the table below.
