SWRO - the largest plant in British waters

The paper describes the operational experience with the newly constructed S WRO plant in Jersey. The plant replaced a multi-stage flash distillation (M SF) plant, commissioned in 1970 by Weir Westgarth, which was operational un til 1996. At the time of supply the MSF plant was considered to be the most energy efficient desalination process with a gain ratio of 12 to 1 to mini mize running costs. Projected operating costs for the new SWRO plant are co mpared with the actual running costs as well as with actual running costs f or the original MSF plant. The environmental impact of both installations i s also addressed. For this particular site the benefits of membrane technol ogy are clearly demonstrated.
