초록 ▼

Ozonated liquid is mixed within a multi-stage clarifier system with wastewater to be treated and suspended solids are removed. The clarified effluent is filtered and exposed to ultraviolet radiation. Ozone is injected into the irradiated effluent and received within a contact tower where reaction between the contaminants and ozone takes place. The ultraviolet irradiated, ozonated, and clarified liquid is recirculated through an ozone injector and discharged through a mixer plate into a purge chamber. The purge chamber effluent is split, with a portion returning to the contact tower and passing through a second ultraviolet radiation source, and the remaining purge chamber effluent being distributed within the clarifiers. After a predetermined residence within the system, a diverter valve in the return line is operable to discharge the treated water through a carbon filter and out of the system. The recirculation of the UV irradiated ozonated liquid provides both effective solids removal and reaction of the contaminants with the ozone to produce an acceptable treated water.

대표청구항 ▼

An apparatus for removal of contaminants from water, comprising: a) a source of contaminated water for treatment; b) a source of ozone; c) a contact tower for residence therein of water undergoing treatment; d) a purge chamber which receives liquid from the contact tower; e) a first recirculation fluid line which carries fluid from the contact tower to the purge chamber; f) an injector located in the first recirculation line and connected to the ozone source to introduce ozone into the purge chamber effluent liquid; g) at least one clarifier tank; a connecting line which directs effluent from the purge chamber to the clarifier tank; h) an influent line connecting the contaminated water source to the clarifier, wherein the contaminated water discharges into the clarifier and contaminated water intermingles with the ozonated effluent therein, the effluent of the clarifier being directed into the contact tower; i) a bypass fitting installed in the connecting line between the purge chamber and the clarifier; j) a return line extending from the bypass fitting and connecting the connecting line to the contact power, the bypass fitting acting to divert a portion of the purge chamber effluent through the return line to the contact tower; k) a second recirculation line connecting the clarifier and the contact tower; l) an ultraviolet radiation source disposed in the second recirculation line between the clarifier and the contact tower so as to irradiate all the liquid which passes into the contact tower from the clarifier; m) a discharge line connected to the return line; and n) a diverter valve located in the return line to permit purge chamber effluent contained in the return line to be selectively directed to the contact tower or discharged through the discharge line from the apparatus as treated effluent from which unacceptable levels of contaminants have been removed.
