### Seawater desalinationmarket

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 2025.

- Water availability and its sanitary state

Extreme risk

(less than 50%)

High risk

Average risk

Low risk

N/a

- Conclusion: considering acute fresh water deficiency, seawater desalination issue has become more and more burning.

Water reserve

Total water volume on Earth is about 1400 mlnkm3

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

Multistage Flash Distillation

Multi-Effect

Distillation

Electrodialysis

Hybrid technologies

Electro-deionisation

Technology shortcomings

Given technologies have essential drawbacks:

- high energy intensity;

- environmental hazards during operation of desalination plants;

- high skilled operating staff required.

Seawater desalination market

- As of the end of 2011 there are 14 865 desalination factories, their aggregate capacities - 67.4 mln m3 per day
- Annual increase in production capacity is about 11.2 %
- In money terms the desalination market is estimated at 12 billions US dollars as of 2011 and this figure is increasing annually
