What kind of maintenance is involved in operating a desalinator ?
A. The main maintenance is to change the fine-grade prefilters, to clean the reverse osmosis membranes, to backwash the media filter – if used. Once every few years, you will have to replace the reverse osmosis membranes. With our module exchange program, it is easy to do. There may be some mechanical maintenance associated with the pumps, the electric motors or diesel engines. Solar electric panels do not need maintenance. If you use storage batteries, then they may need addition of water from time to time and may need replacement after a few years. Q. What is the operating cost for desalinators. A. The range of operating costs for brackish water desalinators is US$ 0.22 – 0.65 per m3 of purified water. The range of operating costs for electric powered desalinators is US$ 0.60 – 1.80 per m3 of fresh water. The range of operating costs for diesel powered desalinators is US$ 0.43 – 1.20 per m3 of fresh water. The operating cost for solar powered desalinators is about US$ 0.55 per m3 of
