Abstract

The invention relates to a method, apparatus and system for the treatment of organic and inorganic waste in a waste fluid. The method involves a co-current plug flow of fluid in a reactor in which ozone mass transfer conforms to the effective life of the ozone used in the treatment. Hydroxide and hydrogen peroxide can be added to the waste fluid. The combined fluids to be treated travel the reactor through a series of surfaces in a packed reactor. The apparatus includes a diffuser for ozone which assists in the co-current plug flow of fluids. The diffuser can have a porosity of about 10 microns. The invention further envisions a compact system for efficient treatment of waste fluids.
