An Innovative And Advanced Oxidation Process For Effluent Treatment Through Wet Tube-type Electrostatic Precipitation
Published 2012 · Chemistry
Abstract The degradation of hazardous pollutants (organic pollutants/non-biodegradable) in waste water was investigated with wet tube-type electrostatic precipitator (WESP). A WESP equipped with brush discharge electrodes was investigated under various operation conditions to characterize the current/voltage-curves and it was compared with the state of the art empirical correlation mentioned in literature. Experimentally obtained current/voltage data was modeled to develop an adjusted empirical correlation for brush type discharge electrodes. Investigations show that corona current is a function of operation voltage and geometry of discharge electrode. Formation of oxidizing reagents like ozone was investigated and the process was optimized. Degradation of several pollutants like acetone, EDTA and phenol was recorded at specific corona current. A series of investigations was conducted to determine the optimum process conditions without sparking. Degradation rate of organic pollutants is higher in the dominating region of ozone formation. WESP equipped with brush discharge electrode produce an enhanced/uniform corona which is capable of eliminating pollutants from off-gas and wastewater simultaneously.
