Abstract: The present multi-stage photo-catalytic oxidation fluid treatment system that uses a plurality of modules to implement an efficient, scalable and cost effective fluid treatment process to remove contaminants from a fluid. The multi-stage photo-catalytic oxidation fluid treatment system relies on mechanical and electronic elements, instead of chemicals, to treat the fluid that is input to the system and provide enhanced treatment of the contaminated fluid. The use of ozone and ions causes reactions with the contaminants that are contained in the fluid to purge the contaminants from the fluid or convert the contaminants to a form where they can be removed from the fluid or are rendered harmless.

Abstract: A system for treating a contaminated liquid wherein atmospheric air is fed into an oxygen generator with the resulting gases fed into an ozone generator and the resulting gases fed into a treatment tower as the contaminated liquid flows through the treatment tower is modified by locating apparatus between the oxygen generator and the ozone generator which apparatus receives the gases from the oxygen generator, ionizes such gases and feeds the ionized gases to the ozone generator.
