Oval wastewater treatment plants with integrated pumping station

Wastewater treatment plants AT 30 oval iPS to AT 225 oval iPS are designed for decentralized and semi-centralized wastewater treatment solutions. They are intended for sewage sources of the size from 4.5 to 33.8 m3 / day. Supplied separately with integrated pumping station (iPS) with mechanical pre-treatment. The technological line can be extended with a sludge tank.

They are used for sewage treatment from 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 treated wastewater can either discharge into the surface or underground water, respectively it can be reused for irrigation.

AT 30 to AT 225 oval iPS wastewater treatment plants with integrated pumping stationThe generation of oval wastewater treatment plants with an integrated pumping station brings many benefits.

  • water inflow 1300 mm below the ground
  • plug and play installation

Vertical Flow Labyrinth – VFL® - wastewater treatment technology

The AT 30 oval iPS to AT 225 oval iPS wastewater treatment plants are ideally suited for conventional truck or container transportation.

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. The quality of purified water corresponds with the Directive No. 359/2022 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:

AT 30 to AT 225 oval iPS wastewater treatment plants installation
 
Are installed into the prepared hole as underground tanks on a concrete slab with a thickness of about 300 mm so that the top edge of the revision manholes overlaps about 50 mm above the terrain. Wastewater treatment plant is reinforced, without the need of putting concrete around.
The backfill of the tanks is done with a sorted material of 4/8 mm fraction.
The backfill should be done by layers, while creating a back pressure by filling the water into the tank.
