Operating experiences of a 15,000 cubic meter per day municipal desalting plant at Corfu, Greece

Abstract

The initial eighteen month period of operation of the 15,000 m 3/day municipal plant on the Island of Corfu, Greece, is described. The 15,000 m 3/day desalting plant employing the electrodialysis reversal process (EDR) produces potable water (500 ppm) from a blend of brackish sources with salinities up to 2000 ppm TDS. The paper describes the plant and integration of the plant into the municipal system. The unique system employed to segregate the treatment of the different brackish waters employing only the highest salinity water for blowdown water is also described. The plant was started up in the fall of 1977 and provided water to the municipal system during the 1978 season. The paper presents operating cost data for this period and compares these costs with projected costs which form part of the contractual agreement, with the Municipality.
