Abstract

A treatment system for liquids includes apparatus for dissolving gas in the liquid and a container for providing the necessary reaction time between the gas and liquid or constituents thereof. The device for dissolving the gas in the liquid includes gas injection means for introducing gas into the liquid and a contact chamber for containing a downflowing stream of the liquid to be treated. The pressure within the downflowing stream increases as it descends and at the elevated pressure the capacity of the liquid to take gas into solution is greatly increased. This apparatus for dissolving gas may conveniently be located below ground level. A conduit return means is provided for routing undissolved gas from a region at high pressure to an upstream portion of the liquid stream so that the gas can be reintroduced for dissolution.
