Biofouling control in reverse osmosis membranes using rapid biofiltration technology

Current research has shown that pre-treatment of feed water with the so-called DeNutritor reduces the biofouling rate on membranes Reference RO module DeNutritor RO module 1st cleaning 2nd cleaning 3rd cleaning Configuration 1 Configuration 2 4th cleaning 5th cleaning (only reference module) 9500 10000 10500 11000 11500 12000 Time (h) Fig. 3.
