Production costs of desalinated water depends on operation costs and capital investment. To reduce operation costs in evaporative desalination processes, basically energy consumption, means generally more heat transfer area and/or increased number of evaporation stages resulting higher investment costs. In order to overcome the cost circle, AQUAMAX has developed a new, patented evaporator technology, which makes possible to build low energy consumption evaporators with reasonable investment costs. The unique innovation of the technology is the evaporation heat exchanger, which is made of high quality, flexible plastic materials. AQUAMAX evaporators are operated at low temperatures, 40-60 deg C, with low temperature differences, 2.3-3 deg C. In these circumstances the pressure difference over the exchanger walls is only 10-25 cm water column and the tensile stress is 0.5-1 N/mm2. Typical yield strength for plastic films is 10-25 N/mm2 exceeding well requirements. Also the corrosion resistance of the plastics against seawater and most waste waters and chemicals is very good as generally known. Several AQUAMAX MVC-evaporators have proved their efficiency by producing distilled water with specific energy consumpiton of 8-9 kWh/m3. The applications at the moment include desalination and waste water evaproation in the capacity range of 50-1200 m3/d.
