Waste Treatment System

A waste treatment system including at least one treatment chamber through which a fluid to be treated is moved in a fluid flow, the at least one treatment chamber including:

• i. a plurality of ultraviolet light sources configured to irradiate fluid in the at least one treatment chamber with light at a wavelength of from 240 nm to 400 nm;
• and
• ii. at least one dispersion assembly located at a base of the treatment chamber to disperse ozone supplied to the treatment chamber in a counter flow direction to the fluid flow;
• and
• at least one ozone generation chamber configured to supply ozone to the at least one dispersion assembly, wherein the at least one ozone generation chamber includes a gas inlet for introduction of an oxygen-containing gas, and at least one ultraviolet light source, wherein the at least one ultraviolet light source is configured to irradiate oxygen-containing gas in the at least one ozone generation chamber with light at a wavelength of from 50 nm to 240 nm to thereby produce ozone.
