Activated sludge and septage treatment
Activated sludge treatment
A traditional wastewater treatment plant separates wastewaters into clean waters, that are discharged into the environment, and sludge that has to be dehydrated before being spread or used as compost, e.g. by filtering through sludge drying reed beds.
It is admitted that reduction of the amount of sludge occurs in SDRBs both with dewatering (drainage and evapotranspiration) and aerobic mineralization.
“An optimized design and a strong operating assistance given by Epur Nature make this process a reliable and sustainable sludge treatment technology”.

Septage treatment
Septage is usually concentrated matter that the cesspool cleaner remove from the septic tank for people with an individual system. The septage is generally transported for treatment to large urban stations (>10,000 PE) but can also be treated in special installations that use the reed drying bed (RDB) principle. For communities without a sludge purification station, the RDB system offers a certain degree of independence and an ecological solution for treating this by-product.
We are participating in these developments as members of the steering commission for the experimental installation in Andancette, Drôme.
