20120255908 | WATER CONSERVATION METHODS COMBINING OSMOTIC MEMBRANE PROCESSED WATER FOR SUBSEQUENT EFFICIENT USE IN COOLING TOWER APPLICATIONS - Synergies in recovery of reverse osmosis (RO) membrane process reject waste and forward osmosis (FO) membrane process water extraction, using such osmotic process byproducts in applications for makeup to evaporative cooling towers, concurrent with use of specific corrosion and scale inhibition methods that permit tower water discharge reduction to approach zero blowdown. Such synergies are derived from methods for application of subsequent RO feed water and reject wastewater with pre-treatment steps, and FO process optimization steps to permit water quality and economic performance efficiencies when used as makeup to evaporative cooling systems. | 10-11-2012 |
