Abstract

The present disclosure relates to a process for treating and regenerating a spent caustic solution at ambient temperatures and pressure which includes oxidizing spent caustic wastewater with a brine solution and ozone mixture, supported by irradiation of the spent caustic wastewater by ultrasound. A range of wastewater treatment techniques may also be included to reach a desired effluent quality level.

IPC Classes  ?

• C02F 1/36 - Treatment of water, waste water, or sewage with mechanical oscillations ultrasonic vibrations
• C02F 1/66 - Treatment of water, waste water, or sewage by neutralisationTreatment of water, waste water, or sewage pH adjustment
• C02F 1/78 - Treatment of water, waste water, or sewage by oxidation with ozone
• C02F 9/04 - Multistep treatment of water, waste water or sewage at least one step being a chemical treatment
