Solar energy for industrial water conditioning

The objective of this project is to develop a new technological process of low energy consumption to treat water with a high concentration of mining salts.

The current development of the country leads to an increase of productive activities, which impact on natural resources, particularly on water resources. In this regard, it is important to note that the water availability per capita is less than 1,000 m3/inh/day from the IV to the III region (DGA, National Water Policy, SDT nr 28). This is considered a restriction for the economic development. For this reason, the water has become a limiting resource for the economic development of the region.

The current technologies for these resources require significant amounts of energy and generate water for productive uses in agriculture and mining (the reverse osmosis generates water less than 500 ppm of total dissolved solids). There are no technologies on the market which allow to generate industrial quality water or irrigation water according to the client’s needs

In this way Fundación Chile, through its energy and climate change unit, will investigate and develop a new technological process of low energy consumption, from reverse osmosis membranes and nanofiltration. This project seeks to demonstrate the use of the technology of low energy consumption of membranes, using the solar energy for the conditioning of industrial waters.
The main results of this project are: a constructed pilot plant which operates in a mining field; a market research: a business model to commercialize the technology.
