“…The effects of parameters such as feed concentration, ionic strength, transmembrane pressure, and recovery on the elimination of phenol were studied [28]. Khazaali et al studied Bisphenol A (BPA) removal from aqueous solutions using a low-pressure RO system, an improvement over conventional RO, consuming less energy, having a lower pressure requirement, good rejection, and higher water flux [9].…”

“…However, consideration must be given to membrane fouling which can occur due to particles and colloids present in the feed streams [3,9]. The most important membrane technologies used to remove phenols from wastewater are extractive membrane bioreactors and hollow fiber membranes; photocatalytic membrane reactors; high-pressure membrane processes such as nanofiltration, reverse osmosis, and pervaporation; and membrane distillation [3,9,24].…”

“…Thus, there is a need to treat wastewater affected with phenolic compounds before discharge. Phenol exists in common derivatives such as Bisphenol A (BPA) [9], chlorophenols (CPs), and phenolic endocrine disrupting compounds [10]. The technologies described in this paper for removing phenols from industrial wastewater are classified as conventional and advanced methods.…”

Phenolic compounds are priority pollutants with high toxicity even at low concentrations. In this review, the efficiency of both conventional and advanced treatment methods is discussed. The applicability of these treatments with phenol and some common derivatives is compared. Conventional treatments such as distillation, absorption, extraction, chemical oxidation, and electrochemical oxidation show high efficiencies with various phenolic compounds, while advanced treatments such as Fenton processes, ozonation, wet air oxidation, and photochemical treatment use less chemicals compared to the conventional ones but have high energy costs. Compared to physicochemical treatment, biological treatment is environmentally friendly and energy saving, but it cannot treat high concentration pollutants. Enzymatic treatment has proven to be the best way to treat various phenolic compounds under mild conditions with different enzymes such as peroxidases, laccases, and tyrosinases.

“…For NF/RO membrane, the main mechanism governing the removal is based on sieving effect, while it is adsorption mechanism in UF membrane (Yüksel et al 2013;Zhang et al 2006). In certain cases, the BPA removal of dense membranes is also dependent on the physico-chemical properties of the targeted compound and membrane material (Khazaali et al 2013;Kimura et al 2004). Another advantage of using UF membrane for BPA removal is its significantly higher permeate flux.…”

Bisphenol A (BPA) is one of the recalcitrant contaminants that are detected in drinking water sources, as the conventional water treatment plant is incapable of removing it completely. This study was conducted to explore the performance of ultrafiltration (UF) membrane system for the BPA removal in which BPA was spiked in water sample collected from a treatment plant. The effects of process conditions that may influence the removal and flux performance of the membrane including operating pressure, feed pH and BPA concentration, and backwash cleaning were investigated. The results showed that an applied pressure of 1 bar was the optimum pressure for achieving good balance of BPA removal (95 %) and water flux (109 L m −2 h −1 ) compared to operating pressure of 0.5 and 1.5 bar. The variation of feed pH showed significant impact on BPA elimination with the highest rejection (90 %) achieved at pH 7 while the lowest removal (20 %) at pH 10. BPA concentration had no significant impact on BPA removal as high removal rate (>95 %) was observed regardless of feed concentration (between 10 and 100 μg L −1 ). The normalized flux showed decreasing trend with filtration cycle due to increased membrane resistance of BPA adsorption onto the membrane. The membrane cleaning via backwash was able to recover 90 % BPA removal even after three consecutive cycles of filtration. This indicated the promising performance of UF membrane system for industrial water treatment.Concentration of permeate (μg L −1 ) FRR Flux recovery ratio (%) J 0Pure water flux of membrane before cleaning (L m −2 h −1 ) J c Pure water flux of membrane after cleaning (L m −2 h −1 ) J wWater flux (L m −2 h −1 ) R Removal of BPA (%) R f Fouling resistance (m −1 ) R m Intrinsic membrane resistance (m −1 )

“…The ability of pressure driven membrane processes for removal of organic compounds from wastewaters has been reported [14]. NF/RO processes have been widely used for contaminant removal in advanced water and wastewater treatment and desalination [19][20][21]. Recently, reverse osmosis (RO) membrane technology has attracted much attention due to its preponderance than other separation techniques [22].…”

2015) Effect of operating parameters on 2-chlorophenol removal from wastewaters by a low-pressure reverse osmosis system, Desalination and Water Treatment, 55:1, 114-124, A B S T R A C TIn this study, the performance of a commercial low-pressure reverse osmosis membrane system (TW30-1812-100) was evaluated for 2-chlorophenol removal from wastewaters. The influence of various operational conditions and system specifications such as feed pressure, feed flow rate, pH, and concentration on 2-chlorophenol rejection was investigated. The results showed that at optimum conditions (200 ppm feed concentration, 408.1 kPa feed pressure, pH 10, and 1.953 × 10 −5 m 3 /s feed flow rate) 79% rejection was attainable. In addition, it was found that at the feed pH was the most effective parameter on 2-chlorophenol rejection. The rejection was increased with feed pH. An increase of feed flow rate had a positive effect on 2-chlorophenol rejection. The study of the influence of feed pressure showed a maximum critical pressure for rejection. However, the study of feed concentration on 2-chlorophenol rejection did not show a clear trend.
