Residential wastewater treatment plants Aquatec VFL - AT 6 - AT 20

VFL

AT6 - AT20 residential wastewater treatment plants were invented to purify sewage water for detached houses. 

Wastewater treatment plants of the AT 6 to AT 20 series are solutions and bring benefits for every household:

  • Clean water directly at source of pollution
  • Low operating costs of wastewater treatment unit
  • Operation up to 8 times cheaper compared to the cesspool
  • High quality purified water
  • Reuse of purified water
  • Quiet, odorless
  • Meets the prescribed EN 12566-3 standard

Purified waste water can be discharged into surface or underground water, recycle it by using for irrigation of lawns and ornamental greenery or use it for technical purposes after filtration.

Aquatec VFL service and maintenance of wastewater treatment plants
Simple installation of AT wastewater treatment plants
WWTPs of the type AT 6 to AT 20 are installed into a pit with a 15 cm thick reinforced concrete slab on the bottom, so that the upper edge of the WWTP tank overlaps about 5 cm above the terrain. If necessary, and if the design documentation requires it, the WWTP is to be concreted to the height specified by the project documentation. WWTP must be filled with water (to the outflow pipe level) before doing the backfill. Detailed instructions for installing of WWTPs are given in the operating instructions annexed. The Aquatec VFL technical team can take care of the installation.

Vertical Flow Labyrinth – VFL® - Treatment process
     
The technology uses a continuous-flow activated sludge process with biological nitrogen and phosphorus removal, which combines the following processes in a single tank:  mechanical pre-treatment, excess sludge collection, biological treatment using a low-loaded activated sludge process, separation of the treated water from activated sludge in the final clarification chamber, flow balancing of fluctuating inflow of wastewater in the retention chamber. The treatment process consists of several technological processes. Raw wastewater flows into the non-aerated activated sludge chamber with anaerobic and anoxic zones creating and admixture with the recirculated activated sludge, the mechanical pre-treatment of inflowing raw wastewater and the decomposition of coarse impurities, denitrification and accumulation of readily degradable organic contamination is taking place in the non-aerated activated sludge chamber, which is divided by inner partition walls to create a vertical flow labyrinth, where internal circulation is established. 
Furthermore, allowing the admixture flow gravitationally into the aerated activated sludge chamber with includes fine-bubble diffusors. In oxic conditions the biological degradation of organic contamination, nitrification and phosphorus uptake is taking place.  The activated sludge flows into the final clarification chamber, where the activated sludge is separated from the treated wastewater. The treated wastewater is discharged into a water flow, infiltrated or recycled and the separated activated sludge is recirculated by air-lifts.
A flow regulator is installed at the water level in the final clarification chamber which controls the outflow in order to maintain the water level between the normal and maximum level in the tank (integrated retention chamber).
The pressurized air is supplied by blowers for aeration of the activated sludge chamber and for recirculation via air-lift pumps. The recirculation and aeration is controlled by a microprocessor control unit which also enables the wastewater treatment plant to work in various modes depending on the loading.

The AT wastewater treatment plant meet the requirements for the resistance of inflowing sewage water abruptly. Ensuring the homogeneous operation of the wastewater treatment plant in the event of abrupt outpour of high volume of water (e.g. bathtub, washing machine, etc.). The wastewater treatment plant main problem is respect to the discharge of the activated sludge upon every abrupt inflow resulting in solving this issue.
