Treatment of phenol in synthetic saline wastewater by solvent extraction and two-phase membrane biodegradation

A study on a combined process for the treatment of phenolic resin plant effluents

“…In fact, solvent extraction method finds some advantages in treating phenolic wastewater, which is justified with the work published in literature [7,8]. Most recently, Juang et al [9] reported the treatment of a phenolic wastewater by solvent extraction and membrane biodegradation in hollow fibres. Our research group also studied the removal and recovery of phenol and formaldehyde from a phenolic resin plant effluent by using solvent extraction [10,11].…”

Experimental investigation of bio-removal of toxic organic pollutants from highly saline solutions in a triphasic system

“…It is expected that the S cm,max value can be controlled via the selection of suitable solvents. On the other hand, biphasic biodegradation process can also be operated in microporous hollow-fiber membrane contactors [20,21]. For treating toxic organics in saline and acidic wastewaters, for example, phenol in wastewater was first extracted by kerosene in a batch vessel, and the loaded solvent was passed through the lumen of polyvinylidene fluoride hollow fibers (pore size 0.2 m, area 0.02 m 2 ); simultaneously, P. putida BCRC 14365 in the MS medium was flowed across the shell.…”

Phenolic wastewater treatment through extractive recovery coupled with biodegradation in a two-phase partitioning membrane bioreactor

“…Recently, membrane-based TPPB configurations have been developed, wherein the aqueous and the organic phases could be physically separated using semi-permeable membranes (Juang et al, 2009;Loh, 2013a, 2014). The resulting two-phase partitioning membrane bioreactors (TPPMB) had the advantage of dispersion-free mass transfer, easy NAP recycle, solvent-free cell growth environment and simultaneous extraction and biodegradation.…”
