Application of membrane technology to power generation waters

Three membrane technlogies (reverse osmosis, ultrafiltration, and electrodialysis) for wastewater treatment and reuse at electric generating power plants were examined. Recirculating condenser water, ash sluice water, coal pile drainage, boiler blowdown and makeup treatment wastes, chemical cleaning wastes, wet SO/sub 2/ scrubber wastes, and miscellaneous wastes were studied. In addition, membrane separation of toxic substances in wastewater was also addressed. Waste characteristics, applicable regulations, feasible membrane processes, and cost information were analyzed for each waste stream. A users' guide to reverse osmosis was developed and is provided in an appendix.
