Dear Anthony, Thanks for your comments. 1. The MSF process requires a large flow of seawater or brine to be circulated in condensers. This results in a specific extra electricity consumption of 3 to 4 kWh/m3 for MSF plants over MED plants which do not require such circulation. This gives a cost advantage of MED plants over MSF plants. 2. Elevated temperature values are characteristic of distillation plant effluents only. The thermal pollution depends on the size of the plant and quantity of effluent. The thermal pollution of a 1.59 mgd (6000 m3 day-1) MSF desalination plant raises the temperature by about 9°C. The total discharge brine is 1980 t h-1 (0.55 m3 s -1) with an approximate salinity of 12.6 per cent. http://www.desware.net/sample-chapters/d02/d00-010.pdf Best regards, Nikhilesh
