Drank and Principe :

Drank : Water treatment before rejection not polluting in natural environment.

Principle : A specific bioreactor associated with ultrafiltration by membranes.

Specified standard "MEPC-2(V1)"



       - Collect black water in the special bioreactor.

     - The organic matter is treated, without odors, nor degasification.

     - Water charged resulting from the process circulates through especially dimensioned filter membranes.

     - The filtrate thus recovered is evacuated in natural environment.


This modular system can be adapted for daily outputs from 150L to 1500L/day, by appropriate tank additions, pumps and filters.

The system is entirely automatic, controlled by an automat. The information necessary for the automat is transmitted by sensors (flows, pressures, levels, functioning/pump, alarms, setting judgement in safety, etc...).




Once per annum or after each stop of more than 15 days, clear water rinsing tanks and the filters.
