Trends and current practices of olive mill wastewater treatment: Application of integrated membrane process and its future perspective

摘要

Olive oil production releases huge volume of environmentally detrimental wastewater. The wastewater is rich in biophenolic compounds that exhibit both phytotoxicity and pharmacology interesting bioactivities. This review analyzes recent developments made in the treatment of olive mill wastewater (OMWW) through analysis of patents, researches articles and industrial practices. Research articles and patents over the last 20 years are classified chronologically and geographically. Paradigm shift from simple detoxification to valorization based on used treatment strategies is illustrated. Clear time line in the main strategies followed to solve OMWW related environmental pollution is plotted. Special focus is given to the potential of integrated membrane process to valorize this stream. Progressive development and significant rise in the use of integrated membrane process, showed a huge potential for combined wastewater treatment and co-product valorization.
