Recognising the importance of the global problem of water, and more specifically the treatment thereof, Aqua Dyn - Auroville aims to produce pure, clean and ""living"" water beneficial to good health.The systems for water treatment of Aqua Dyn - Auroville range from simple micro filtration with activated charcoal filter and ultraviolet light (for municipal water supplies with frequent chemical and bacteriological contamination) to the most advanced technologies such as ultra-filtration for turbid water (rain water recovery) and reverse osmosis for saline water (intrusion of sea water into aquifers).
