Demineralization of carbon-treated secondary effluent by a 45.5 1 pm (12 gpm) Ionics electrodialysis pilot plant was investigated at the Pomona Advanced Wastewater Treatment Research Facility, Pomona, California. Slime formation (organic fouling) on the membranes and spacers of the electrodialysis stack during continuous operation significantly decreased the effectiveness of the electrodialysis process to demineralize municipal wastewater. If the total COD of the feedwater was maintained at or below 10 mg/l, a weekly enzyme-detergent flush maintained the total dissolved solids (TDS) removal in the design range of 30-35 percent. A cost estimate for a 10 MGD single stage electrodialysis plant based on the operating results obtained at Pomona was made. The estimated cost of 19.4 cents per 1,000 gallons was based on the use of carbon-treated secondary effluent with an average TDS concentration of 540 mg/l and a total COD of 10 mg/l or less to produce a product water with 30-35 percent reduction in TDS.
