ABSTRACT:
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.
