Wastewater treatment process with an ozone contactor

A process for the oxidation or photooxidation of wastewater containing oxidizable or photooxidizable contaminants comprising a step for introducing a gaseous oxidizing agent into the wastewater to form a combined mixture, passing the combined mixture first through a liquid ring compressor then through ultraviolet light reactor so as to permit said oxidizing agent to oxidize said contaminants and thereafter passing the combined mixture to a working tank from which said combined mixture is further recycled to said introducing step until the oxidizable contaminants of the wastewater stream are substantially destroyed, wherein said ring compressor provides intimate contact of said wastewater with said oxidizing agent while increasing the throughput of said wastewater through said process without utilizing an absorption column.

In a process for the oxidation or photooxidation of oxidizable or photooxidizable contaminants in wastewater in which the contaminants in the wastewater are exposed to a gaseous oxidizing agent by combining a stream of the wastewater and a stream of the oxidizing agent and passing the combined stream through an ultraviolet light reactor, the improvement wherein said wastewater is contacted with said gaseous oxidizing agent by providing a step in which each are introduced into a liquid ring compressor to form a combined stream which is thereafter passed to a working tank from which said combined stream is further recycled to said introducing step until the oxidizable contaminants of the wastewater stream are substantially destroyed, wherein said ring compressor provides intimate contact of said wastewater with said oxidizing agent while increasing the throughput of said wastewater through said process without utilizing an absorption column.

A process for the oxidation or photooxidation of wastewater containing oxidizable or photooxidizable contaminants comprising a step for introducing a gaseous oxidizing agent stream and a wastewater stream into a liquid ring compressor to form a combined stream and then passing the combined stream through an ultraviolet light reactor so as to permit said oxidizing agent to oxidize said contaminants and thereafter passing said combined steam to a working tank from which said combined stream is further recycled to said introducing step until the oxidizable contaminants of the wastewater stream are substantially destroyed, wherein said ring compressor provides intimate contact of said wastewater with said oxidizing agent while increasing the throughput of said wastewater through said process without utilizing an absorption column.
