Two new types of resins were subjected to laboratory evaluations of their technical and economic feasibility for use in phosphate removal. Multi-valent metal derivatives of sulfonic acid resins were found to have good phosphorus capacities. The Iron (III) form of Amberlite 200 strong acid cation exchange resin, for example, exhibited capacities of up to 9.5 mg P/ml of wet resin, and in tests with secondary effluent, a 2.7 mg P/ml capacity was obtained. Exhausted resin was easily regenerable with dilute ferric chloride solution, and after ten exhaustion-regeneration cycles were performed on one sample, no detectable loss of phosphorus capacity was observed. The iron and phosphorus removed from the wastewater and concentrated in the waste brine were subsequently removed from the waste brine by lime addition and settling. A thorough cost analysis including both fixed construction costs as well as operation and maintenance costs, established the price of wastewater treatment by this method as 34.38 cents/gal. (Author)
