Abstract

A system and method for treating "septage" (i.e., wastewater collected from septic tanks and similar installations) utilizes a reactor tank for treating the anaerobic wastewater with an oxygen-containing fluid so as to substantially increase the dissolved oxygen content and thereby render the wastewater aerobic and suitable for input into a municipal wastewater treatment facility. Volatile gases are drawn off from all of the reactor tanks and placed into a treatment tank for a reduction of the bacterial and odor levels by reaction with a chlorine-containing water output of the municipal wastewater treatment facility.
