Abstract: A compact, compartmentalized sewage treatment apparatus housed in a single tank having a length appreciably greater than its height in which sewage discharged into the apparatus is progressively clarified by anerobic bacterial decomposition, primary sedimentation and flotation, chemical attack to reduce coliform bacteria and BOD, and secondary sedimentation, flotation and filtration to highly clarify the effluent for discharge into lakes, rivers, harbors and other water courses.

Abstract: A SELF-CONTAINED SEWAGE SYSTEM IN WHICH A MICROWAVE ENERGY SOURCE IS PROVIDED TO VAPORIZE THE LIQUID HASE OF THE SEWAGE SO THAT IT MAY BE REMOVED FROM THE SYSTEM AND THE INTERVAL BETWEEN SERVICINGS OF THE SYSTEM LENGTHENED. THE SEWAGE IS TRANSFERRED FROM THE SEWAGE RECEIVING TANK TO AN EVAPORATING TANK FOR EVAPORATION AND, IN CERTAIN EMBODIMENTS USED IN SITUATIONS WHERE POWER IS NOT AT A PREMIUM, A PORTION OF THE LIQUID VAPORIZED FROM THE SEWAGE MAY BE RETURNED TO THE SYSTEM FOR FLUSHING PURPOSES.
