A catalytic ozonation reactor design for reuse large scale industrial wastewater: Laundry

Abstract

Large-scale industrial wastewater is a longstanding problem, but considerations of the industrial wastewater treatment progress are unusual, and the design of wastewater treatment required by industry is severely deficient. To make industrial wastewater an economically viable source of clean water, we propose a logical approach towards designing a large scale catalytic ozonation reactor for reuse large scale industrial wastewater. ANSYS software is used as a primary tool to estimate the ozone transfer and catalytic performance of the reactor, and the effects of reactor design are investigated. The ozone transfer of 100 g/h, energy consumption rate of 3 kWh and a catalytic time of 120 seconds are all within acceptable ranges typical to industrial wastewater. It is estimated that a double catalytic ozonation reactor of 5 m3 can supply the clean water demand of 100 m3/day.
