Abstract

Small quantities of O3 are efficiently contacted with large volumes of polluted water in three successive stages; (1) O3 is entrained by water injector, (2) the O3-contg. water is injected into flow path between water source and treatment tank, and O3 is dispersed through large vol. of water and (3) flow then enters treatment tank near base and is distributed through it.
