Mobile and floating flash distillation plants
A single mobile floating desalination plant could serve the increasing water requirements of several scattered communities such as those living on a group of islands or along an arid coastline. The use of such plants could satisfy the requirements of small communities for additional high quality water supplies where the present demand does not justify the installation and operation of several small land-based desalination plants and where the cost of transporting alternative water supplies is high. The inherent flexibility of a mobile plant would enable seasonal peak demands of certain communities to be readily met.This paper presents the results of a design study of a mobile and floating desalination plant with a fresh water production capacity of 200,000 igpd (909 m3/d). The capital cost of such a facility has been estimated to be £ 384,000. This plant could supply each of 60,000 persons in 12 isolated communities with 2.7 igpd (12 litres/pay) of fresh water at a cost of 26/-d per 1,000 Imp. gallons.
