GE's RePAK Reducing Water Consumption

Pennsylvania Power Plant Saves 1.3 Million Gallons of Drinking Water per Day afterInstalling GE's Advanced Water Reuse Technology

Covanta's Delaware Valley energy-from-waste facility in Chester, Pennsylvania,has saved 1.3 million gallons a day (MGD) from local water supplies by installing GE's advancedRePAK* water reuse technology in the power plant's cooling tower. GE honored Covanta with the Return onEnvironment (ROE) award to recognize the company for its noteworthy reductions in water usage.The Chester facility generates up to 90 megawatts of clean energy from 3,510 tons per day of municipal solidwaste. Previously, the plant used 1.3 MGD—or nearly 5 million liters a day—of municipal drinking water in itswaste conversion process, costing the company thousands of dollars in daily water purchases.To reduce facility operating expenses and the consumption of local water resources, Covanta Delaware Valleyupgraded the facility by installing GE's RePAK combination ultrafiltration (UF) and reverse osmosis (RO) systemas a tertiary treatment package. The new system enabled the plant to reuse 1.3 MGD of treated discharge waterfrom a nearby municipal wastewater treatment plant for the facility's cooling tower.

GE installed two RePAK-450 trains, each producing 450 gallons per minute of purified water. As a result,Covanta Delaware Valley has eliminated the need to purchase 1.3 MGD of local drinking water a day, whichresults in a substantial financial savings in addition to the extremely favorable environmental benefits.
