What is REUSE?

REUSE or reuse of treated wastewater is about reducing the pressure of withdrawal on water resources. Countries with drought problems use this technique extensively. Biological treatment for REUSE is as important as the use of a filter, given its efficiency.

In France, a study shows that we are at 0.4% of treated water reused, especially in the north. And between these waters’ applications, we could mention:

  • First, the water from the rain;
  • then the water on the surface;
  • wastewater from mines and quarries
  • And finally industrial wastewater (even though it is subject to different regulations).

What is the purpose of biological treatment in the REUSE process?

The treatment of industrial wastewater uses a filter that is easily integrated into the treatment of a wastewater treatment plant. This will reduce any impurities and suspended solids in the water suitable for REUSE and its role is the same as a pond. It provides mechanical filtration adapted to water production and removes particles larger than the mesh diameter. For a REUSE water treatment plant, a filter with optimized washing is ideal for highly concentrated and less water-saturated sludge. Ce filtrage permet de diminuer au minimum les consommations d’eau. However, the difference with aquaponics is that the sludge used will not be systematically mineralized. This is because the filter coupled with another filtering system such as an MBBR will provide biological filtration. However, mechanical filtration alone will not remove all impurities. in a tank. ABiological treatment for REUSE is necessary, as is the application of aquaculture. Thanks to these two processes aerobic and anaerobic biological treatment, the water will be completely purified of remaining substances and the odors associated with wastewater treatment will be reduced.
