Abstract
EC is found to be effective for removing TOC and hardness from both the actual and synthetic shale gas wastewaters. The electric energy required per unit mass (EEM) for removal of TOC for ASWW, SSWW - LDS and SSWW - HDS are 243, 102 and 70Â kWh/kg respectively. The EEM for removal of hardness for ASWW, SSWW - LDS and SSWW - HDS are 303, 104 and 25Â kWh/kg respectively. The high conductivity of SSWW - HDS helps in achieving higher currents and hence the lower reported EEM values for SSWW - HDS. Also, under alkaline conditions, the performance of EC increases significantly. Combination of aeration with EC is also found to increase the performance of EC, especially for wastewater containing high concentrations of chloride ions.
