摘要： An apparatus and method for treating for disposal organic waste material carried within a sludge, by adding to the sludge an alkali metal silicate and a setting agent, is disclosed. The apparatus includes several mixers, each having a trough with an input end and a discharge end, at least one rotatable shaft mounted longitudinally along the trough, a plurality of blades mounted to the shaft, and a drive for rotating the shaft. The sludge is deposited within a first mixer, and then directed from the mixer into a tank. A series of chopper pumps recirculate the sludge into the tank, and alternatively, the sludge may be passed through an additional mixer. Leaving the tank, the sludge is directed into a second mixer at its input end. Water is introduced at the input end, and a setting agent is added along the trough at a point adjacent the input end. Further along the trough, an alkali metal silicate is introduced. The mixture is recovered from the second mixer, and carried to a remote location for setting.

摘要： A method of treating sewage is disclosed. Sewage is mixed with an ammonia source, and the mixture is formed into a substantially impermeable mass. The substantially impermeable nature of the mixture increases the ammonia concentration therein and substantially completely destroys all viable parasites. When the impermeable mass is formed by addition of cement and silicate, a strongly alkaline environment is created that kills bacteria and viruses. The resulting end product is a friable mass that is substantially free of pathogens and suitable for unrestricted reuse.
