FRESH WATER - PRODUCTION AND PURIFICATION
Fresh water makes up only 3% of the water resources of the Earth, of which 0.5% is available and only 0,003% is used by people for their own needs. From year to year demand for fresh water is growing and, according to the UN data, by 2025 the shortage of fresh water will affect already 2/3 of the world population. We witness water turns from reproducible resource into unreproducible one in the result of booming and thoughtless anthropogenic activities and this is one of dead-end ways for humanity.
