“…Rajesh et al [74] used Newman method humic acid (as the model foulant and HA separation efficiency) in the separation of humic substance from aqueous streams and also applied to estimate the changes in surface free energy and fouling resistance of the membranes, respectively. The prepared membranes were prosperously applied in the separation of humic substance from aqueous streams.…”

“…Many treatment process such as electrocoagulation (EC) (Ulu et al 2014), adsorption , nanofiltration (Rajesh et al 2013), catalytic ozonation (Choi and Rhee 2014), enhanced coagulation (Amin et al 2012) and photocatalysis (Hatakeyama et al 2012;Yuan et al 2013) have been developed for elimination of HS from water. In the past decade, photocatalysis processes have emerged as an efficient technology for removing of organic compounds from aquatic solutions (Gaya and Abdullah 2008;Patsios et al 2013).…”

In this study, Cu-doped ZnO nanoparticles were investigated as an efficient synthesized catalyst for photodegradation of humic substances in aqueous solution under natural sunlight irradiation. Cu-doped ZnO nanocatalyst was prepared through mild hydrothermal method and was characterized using FT-IR, powder XRD and SEM techniques. The effect of operating parameters such as doping ratio, initial pH, catalyst dosage, initial concentrations of humic substances and sunlight illuminance were studied on humic substances degradation efficiency. The results of characterization analyses of samples confirmed the proper synthesis of Cu-doped ZnO nanocatalyst. The experimental results indicated the highest degradation efficiency of HS (99.2%) observed using 1.5% Cu-doped ZnO nanoparticles at reaction time of 120 min. Photocatalytic degradation efficiency of HS in a neutral and acidic pH was much higher than that at alkaline pH. Photocatalytic degradation of HS was enhanced with increasing the catalyst dosage and sunlight illuminance, while increasing the initial HS concentration led to decrease in the degradation efficiency of HS. Conclusively, Cu-doped ZnO nanoparticles can be used as a promising and efficient catalyst for degradation of HS under natural sunlight irradiation.

“…The surface fouling is the main challenge in a HA removal via UF process and plays a crucial role on the membrane performance . Fouling leads to a decrease in membrane efficiency and the resultant flux even after backwashing . The common approach to reduce the membrane fouling is increment of membrane hydrophilicity .…”

“…Also, water permeability of the modified membranes was higher than that one for nascent membrane. Rajesh et al investigated the effect of TiO 2 and combination ratio of polyamide imide (PAI) and polysulfone (PSf) polymers on the separation of HA from water. They resulted that incorporation of PAI and TiO 2 nanoparticles has a huge effect on improvement of morphology, hydrophilicity, pure water flux (PWF), rejection, and antifouling properties of PSf/PAI membranes.…”

New thin film composite (TFC) membrane was prepared via coating of Pebax on PSf‐PES blend membrane as support, and its application in wastewater treatment was investigated. To modify this membrane, hydrophilic TiO2 nanoparticles were coated on its surface at different loadings via dip coating technique. The as‐prepared membrane was characterized using Fourier transform infrared spectroscopy, scanning electron microscopy (SEM), field emission SEM, and contact angle analysis. The Fourier transform infrared spectroscopy analysis and surface SEM images indicated that TiO2 was successfully coated on the membrane surface. In addition, the results stated that the hydrophilicity and roughness of membrane surface increased by addition of TiO2 nanoparticles. Performance of TFC and modified TFC membranes was evaluated through humic acid removal from aqueous solution. Maximum permeate flux and humic acid rejection were obtained at 0.03 and 0.01 wt% TiO2 loadings, respectively. Rejection was enhanced from 96.38% to 98.92% by the increase of feed concentration from 10 to 30 ppm. Additionally, membrane antifouling parameters at different pressures and feed concentration were determined. The results indicated that surface modification of membranes could be an effective method for improvement of membrane antifouling property.
