BIOLAK®Integral System

Plant for the aerobic treatment for communal and industrial wastewater, up to complete recycling.

The system integrates biological phosphate, nitrogen and carbonate reduction, final clarification and advanced treatment in the same basin.



BIOLAK®Integral has been designed for plants of 300 to over 3,000,000 PE60


BIOLAK®Integral has been designed for industrial sewage with capacities from 0.5 to 200 t COD/d. We have experience in:
The food product sector:
  • Breweries/malthouses
  • Soft drink companies
  • Fruit processing
  • Dairies / cheese makers
  • Starch factories
  • Slaughterhouses
  • Tinned food factories
Other industrial water:
  • Textile finishing
  • Paper and cellulose
  • Animal body disposal
  • Petrochemical industry
  • Chemical industry


BIOLAK®Integral was tested under extreme climate conditions, such as in high ambient temperatures (e.g. in Saudi Arabia) and in extremely cold locations (such as Finland).


High treatment efficiency

  • Degree of cleaning > 95%
  • Activated sludge stage with sludge stabilisation
  • Elimination of nitrogen
  • Biological elimination of phosphates
  • Extensive hygienisation
  • Removal of filterable materials (SS<10 mg/l)
  • Post-purge
  • Stable process: this provides operational safety


  • Low energy consumption due to “moving aerator chains”
  • Low level of sludge accumulation
  • Low investment costs due to integral construction method and ground basin structure
  • Natural construction method fitting into the landscape
  • Long lifecycle

Simple maintenance

The maintenance is very simple and inexpensive and can be carried out with no service interruptions.

Secure against earthquakes

BIOLAK®Integral uses the ground basin construction method with HDPE basin sealing and is therefore robust and secure during earthquakes. Small settlement movements are compensated for by the foil.
