What is REUSE?

Wastewater reuse (REUT) recycles wastewater to reduce water demand, especially in dry regions. To ensure its safety, biological treatment and filtration are essential.

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:

  • Rainwater: Water that falls from the sky during precipitation.
  • Surface water: Such as that from lakes or rivers.
  • Mine drainage water: Those originating from mining activities and quarries.
  • Industrial wastewater: Although subject to specific regulations, they can also be treated and reused.

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 filter:
Removes impurities and large particles.
Functions like a retention basin.
Is ideal for REUT, effectively treating dense sludge.
Significantly reduces water consumption.
In short, it purifies industrial water to make it reusable while saving water.

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. It eliminates residues and reduces odors during wastewater treatment through processes. aerobic and anaerobic.
