Abstract

The invention concerns a method whereby the membranes (2) are washed with detergents, or adsorbable chemical or biochemical products on activated carbon. The final rinsing for eliminating the detergents is carried out by passing water through the membrane (2) until the residual concentration of detergents is brought below the maximum permissible concentration in water for human consumption. The improvements are characterised in that the method consists in: drawing, for specific treatment external to the system, one first part of rinsing water of the order of 10 to 20 % of the total volume of water required for final rinsing; introducing the powdered activated carbon in the equipment recycling loop; recycling the volume contained in said recycling loop with added powdered activated carbon through the membrane (2), while the permeate is returned into the chamber (4) wherein the washing or rinsing water is stored and from which said recycling is carried out; said recycling being performed until the powdered activated carbon reaches adsorption equilibrium.
