The Performance of a Hybrid Integrated Forward Osmosis (FO) and Contact Membrane Distillation (CMD) Processes to Threat the Olive Mill Effluents and Recovery of Some Polyphenols

Delia Teresa Sponza and Yudum Biyink

This study investigated a Forward Osmosis (FO) and Contact Membrane Distillation (CMD) hybrid system to treat the pollutants and to recovery of polyphenols from the Olive Mill Effluent Wastewaters (OMEW). The aim is to detect a high quality water production and to detect a strong concentration of the polyphenolic compounds to recoveries them. Before FO; a Polyethylene (PE) membrane filter with hollow fiber was used as pretreatment FO worked as a secondary treatment barrier to remove most contaminants in the feed water and CMD was used to recover the draw solutes from FO effluent and simultaneously produce high-quality reusable water. The effects of increasing temperature on water flux and on the rejection was studies in FO>90% removal yields for COD, TSS and total phenols was detected in the permeate of FO while polyphenols namely catechol, 4-methyl catechol, 2-PHE and 3-PHE were concentrated in the retentate of FO. In the effluent of CMD the removals of pollutants were 99.99% while the polyphenols mentioned above were continued to concentrated. The total cost to treat the OMEW with zero discharge emission was 0,475 € for treat the 10 m3 raw OMEW. The revenue coming from the all polyphenol recoveries was 165.45 €
