Abstract
A system for the purification of contaminated water to produce potable water. The apparatus of the system may be mounted on a mobile platform for use in remote locations or may be sized and adapted for permanent installation. The process ozonates the contaminated water, while the water is maintained under substantially laminar flow conditions, in a series of vessels under countercurrent process flow conditions. The water is treated with sufficient ozone, and the apparatus provides a sufficient residence time, to oxidize pathogens and oxidizable matter. Residual ozone is substantially completely neutralized with ultraviolet radiation. Ozone off gas not dissolved in the water during ozonation is collected and any ozone in the gas is converted to oxygen to prevent ozone release into the atmosphere.
