An apparatus and method of using the apparatus in the final stages of purification of sewage water in which the effluent is placed under pressure by a pump and forced through a filter. Part of the effluent is sampled and chlorinated by a chlorine gas injector and then reintroduced into the lager body of effluent. The entire mixture is held within a detention chamber in order to allow the chlorine to dissipate, and then pumped out into a natural stream through a pipe in which air bubbles are injected in order to replenish the oxygen level.
