desalination Tanks


Desalination is a process whereby minerals are extracted from saline water in order for produce fresh water suitable for human consumption or irrigation. The basic principles of desalination are not a new invention – for hundreds of years people have been distilling salt water into drinking water. Today, many populations in water-scarce regions such as Saudi Arabia, the UAE, Oman, Kuwait, Qatar depend entirely on thousands of large-scale, cutting-edge, high-pressure reverse osmosis desalination processes for their survival. Most of the water used in Israel, is processed through desalination plants. This trend is set to increase around the globe since the UN predicts that 14% of the population worldwide, will experience severe water-scarcity by 2025.

South Africa is no exception when it comes to countries experiencing water shortages. The current water crisis has compelled government to embark upon desalination projects as a solution to the country’s ever-increasing water predicament. It is envisaged that up to 10% of South Africa’s urban water supply may be generated by desalination plants within the next 15 years.
