WTE Power Plant Saves 1.3 Million GPD of Water Daily with Tertiary Water Treatment & Recycling

>” […] The Chester facility generates up to 90 megawatts of clean energy from 3,510 tons per day of municipal solid waste. Previously, the plant used 1.3 MGD — or nearly 5 million liters a day — of municipal drinking water in its waste 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 Valley upgraded the facility by installing GE’s RePAK combination ultrafiltration (UF) and reverse osmosis (RO) system as a tertiary treatment package. The new system enabled the plant to reuse 1.3 MGD of treated discharge water from 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, which results in a substantial financial savings in addition to the environmental benefits.

GE’s RePAK equipment was delivered in 2014, with commissioning taking place the same year, making Covanta Delaware Valley the first North American company to deploy GE’s RePAK technology.

Covanta chose a combined water treatment technology approach because the typical organic and dissolved mineral content of the wastewater requires additional treatment to be suitable for use as cooling tower makeup. RO was selected as the technology of choice, and UF was required as the pretreatment solution.

GE’s RePAK combined treatment system reduces the equipment footprint up to 35 percent as compared to separate UF and RO systems. By combining the UF and RO into a common frame with common controls and GE’s single (patent-pending) multi-functional process tank, GE also is able to reduce the capital costs and field installation expenses when compared to the use of separate UF system and RO systems with multiple process and cleaning tanks, the company says.”<
