Treatment of olive oil mill wastewater by a pulsed high-voltage discharge process; process optimization and combination with Fe+2 and H2O2

摘要

BACKGROUNDOlive oil mill wastewaters (OOMW) have caused major environmental problems because of the high organic load, high total suspended solids, high inert chemical oxygen demand (COD), low pH, a characteristic odour, its dark colour and toxicity to plants. A pulsed high-voltage discharge (PHVD) process was developed as a novel alternative to advanced oxidation processes for effective treatment of OOMW.
