Cooling TowerWater Blow-down Reuse

Poly amide Reverse osmosis elements is used in two-stage desalination process successfully reuse Blow-down of cooling tower water about 80mP3P/h in petrochemical complex. This package return treated wastewater to cooling tower basin & reduce the make-up flow. More ever package meliorates the quality of cooling tower. The recovery is about 70% so 56mP3P/h treated water with high quality (TDS<20ppm) is comeing back to cooling tower basin. The main fouling package membranes is excuse of the special constitution at cooling tower water based on organic material, this fouling engender from chemical injection like corrosion inhibitor, biocide & dispersant that increase COD & make more CIP(cleaning in place) membranes with alkaline detergent at last. In this case an intense pretreatment is required certainly.
