Full Description

The City of Washington, Iowa, has three municipal wells that produce an average of about 350 million gallons per year. Prior to 1993, phosphate was added at each well site to control iron in the water mains. Water from the wells then converged at the plant and was injected with chlorine and caustic soda before storage in a ground reservoir. In response to a drinking water standard violation for radium and in an attempt to improve overall water quality, the City evaluated several treatment alternatives. Electrodialysis reversal (ER) was finally selected as the best treatment option. This paper discusses the design and operation of the city's new ER water treatment plant which was completed in April 1993.
