2 Problem – 1/3 of world population live in the countries with water shortage problems; – according to the experts' forecast this figure will increase to 2/3 by Conclusion: considering acute fresh water deficiency, seawater desalination issue has become more and more burning. Water availability and its sanitary state Extreme risk (less than 50%) High risk Average risk Low risk N/a

3 Water reserve Total water volume on Earth is about 1400 mln km3 Salt waterFresh water %2.5 3% Salt waterShare of total water reserve, % Fresh waterShare of total water reserve, % Oceans96,54Glaciers, perennial snow cover1,74 Salt/brackish groundwater0,93Fresh groundwater0,76 Brackish lakes0,006Ground ice, lakes, soil moisture, atmospheric steam, swamps, rivers, living organism fluids 0,03

4 Known seawater desalination methods - distillation(MSF MD MED MVC); - reverse osmosis (RO); - electrodialysis (ED); - congelation (FR); - ion exchange. Reverse osmosis is a high-demand method in the market Reverse osmosis Multi-Effect Distillation Multistage Flash Distillation Electrodialysis Hybrid technologies Electro-deionisation

5 Technology shortcomings Given technologies have essential drawbacks: - high energy intensity; - environmental hazards during operation of desalination plants; - high skilled operating staff required.

6 Seawater desalination market 1. As of the end of 2011 there are desalination factories, their aggregate capacities mln m3 per day 2. Annual increase in production capacity is about 11.2 % 3. In money terms the desalination market is estimated at 12 billions US dollars as of 2011 and this figure is increasing annually

7 Core desalination market segments Market segment Capacity, m 3 / day On-board desalination plant (on sea vessels) Desalination plants for individual use Desalination plants for collective use Desalination factories> 3500
