Abstract: An effluent processing arrangement which takes liquid effluent from primary treatment. In a first stage the liquid is filtered. In a second stage the filtrate is treated to neutralize bacterial and other contaminants and then in a third stage is sprayed under pressure into the atmosphere to evaporate it. An air blower can be used to assist evaporation. Provision is made for flocculation of effluent and for backwashing of the filter. The main purpose of the arrangement is for treatment of septic tank effluent.
