“…These will turn to be a blockade for the passage of other oil droplets in the water during filtration. Nevertheless, the relationship between operating pressure and oil rejection efficiency is not proportional [ 50 ]. Consequently, 2.0 pphr GO filled NBR membrane is more desirable because it has the highest permeation flux at any operating pressure and high oil rejection efficiency of up to 95.7%.…”

Latex phase blending and crosslinking method was used in this research work to produce nitrile butadiene rubber-graphene oxide (NBR-GO) membranes. This fabrication technique is new and yields environmentally friendly membranes for oil-water separation. GO loading was varied from 0.5 to 2.0 part per hundred-part rubber (pphr) to study its effect on the performance of NBR-GO membrane. GO was found to alter the surface morphology of the NBR matrix by introducing creases and fold on its surface, which then increases the permeation flux and rejection rate efficiency of the membrane. X-Ray diffraction analysis proves that GO was well dispersed in the membrane due to the non-existence of GO fingerprint diffraction peak at 2θ value of 10–12° in the membrane samples. The membrane filled with 2.0 pphr GO has the capability to permeate 7688.54 Lm−2 h−1 water at operating pressure of 0.3 bar with the corresponding rejection rate of oil recorded at 94.89%. As the GO loading increases from 0.5 to 2.0 pphr, fouling on the membrane surface also increases from Rt value of 45.03% to 87.96%. However, 100% recovery on membrane performance could be achieved by chemical backwashing.

“…In their studies regarding the synthesis and characterization of CA-based and nylon-66-based membranes, [49] obtained promising water-oil separation results. When compared to the evaluated commercial CA membranes (Merck Millipore, with a 0.22 µm pore diameter), whose permeate flow rate is 22 L/m 2 .h and oil rejection of 70%, the modified membranes showed a permeate flow rate of 33 L/m 2 .h and an oil rejection percentage close to 95%.…”

At a global level, climate changes have been responsible for alterations in rainfall regimes. Numerous impacts resulting from such complex dynamics negatively affect peoples and nations. Desertification, sandification, floods, and droughts are some evident examples of the transformation the world is undergoing. In Brazil, the past few years have been characterized by long periods of drought in some regions. As a result, there have been considerable drops in the levels of reservoirs that supply important urban and economic axes in the country. Implications on the national economy and entire production chains aggravate the current scenario, along with two long years of the Sars-Cov-2 pandemic period. From this perspective, the present work aims to address the pressing need to adopt technologies and techniques for collecting and treating rainwater. To this end, specialized databases were accessed in order to evaluate ongoing research on the use of polymeric materials to achieve that goal.

Removal of Phenol from Sour Water by Poly(vinyl Alcohol)/Polyamide‐Reverse Osmosis Membranes

et al. 2022

A commercial thin‐film membrane (unmodified) of polyamide improved by poly(vinyl alcohol) (PVA)‐coated membranes (modified) was investigated for separating phenol in sour water by reverse osmosis. Dependences of pressure and pore surface area on flux and phenol rejection were tested. A graphical correlation was found between the relative flux decline and phenol concentration decrease in the feed. The modified membrane provided rejection of 86 % at 2 bar with the highest permeate flux of 8.46 L m−2h−1. The average contact angle for the former membrane was 58.4°, while that for the modified membrane was 49.1°. The reduction in contact angle enhances the surface hydrophilicity of the membrane leading to the antifouling effect. The modified membrane provides 95.4 % flux recovery compared to the unmodified membrane that provides only 66.2 %.
