Industrie automobile

La technologie de traitement des effluents industriels de l'industrie automobile permet de dissocier la peinture aqueuse, les adhésifs et les émulsions de coupe libérés pendant le processus de production. Le principe du traitement des effluents industriels consiste à la stabilisation chimique, la précipitations et la sédimentation, la filtration subséquente et la déshydratation dans un filtre-presse…

The technology for treating the industrial wastewater produced in the automotive industry makes it possible to separate out the aqueous paint, adhesives, and cutting emulsions released during the production process.

The principle of industrial wastewater treatment consists in chemical stabilization, precipitation, and sedimentation, with subsequent filtration and dewatering in a filter press.


  • Minimal built-up area
  • Possibility of location near the production plant
  • Ability to separate both adhesives and paint in spite of a different technological procedure
  • Possibility to use existing tanks and pipelines
  • User-friendly system
  • No charges and fines for releasing polluted wastewater
  • Minimal operating costs
  • Return of investment in approx. 1-3 years

Use in various industrial branches:

  • Paper-making
  • Woodworking
  • Furniture
  • Construction
  • Textile
  • Printing
  • Automotive

Wastewater treatment principle in an AS-ASLI WWTP

The wastewater that is continuously released from the production plant is homogenized in an accumulation plant, where it is stirred with a slow-speed stirrer and pumped via a pipe mixer to a coagulation-sedimentation reactor. After homogenization, the wastewater always has approximately the same pollution quality.

In the pipe mixer, wastewater is adjusted with an alkaline stabilizer to the required pH value. Pollution is separated from wastewater through precipitation by the dosing of coagulant. In this way, the neutralization of wastewater to the required pH value is ensured, to comply with the requirements for water released into the sewerage system.

A more effective filtration capability and the dewatering of precipitated products in the filter press is achieved by the addition of organic flocculant. The treated wastewater complies with the requirements for the biological after-treatment of wastewater in a biological wastewater treatment plant.
