ABSTRACT:
A method of treating a liquid waste or process stream that includes a sludge component and that enhances sludge treatment or stabilization. The sludge is acidified to a pH of less than 4.0 in an oxygen enriched environment. A nitrous acid level is maintained sufficiently high to kill pathogens, in a closed chamber so that the nitrous acid won't be lost from the chamber through volatilization.
