Electrical Plasma Technology for Dye Decolorization in a Continuous Reactor System

Article Preview

Abstract:

An airtight gas electrical plasma reactor was designed with subsequent reaction column to estimate performance of this treatment operating in continuous mode for the remediation of wastewater contaminated by organic dye. It was found that subsequent reaction column contributed great for final dye removal because generated ozone was sufficiently utilized in this system and decolorization behaviors in continuous processes were fitted well with first-order kinetic model.And operating under the conditions of input voltage 45kV, gas flow rate 40 L/h, virgin liquid conductivity and unmodified initial pH, the decolorization efficiencies were, at liquid flow rate of 1.5 L/h, 99.7% for 10 mg/L, 99.5% for 20 mg/L, 97.3% for 30 mg/L and 96.7% for 40 mg/L.
