Figure 1: Experimental approach. Graft PEG to membrane surface to help reduce fouling of hydrophobic solutes [3]. Desalination can be used as a means to replenish freshwater supplies of communities with growing population needs. Reverse osmosis (RO) is a pressure-driven process that requires a semi-permeable membrane to selectively remove salts and other particulate matter from brackish water o...

Reverse osmosis (RO) spiral wound membrane generation reached 93.5% in 2020, resulting 14,000 tons of used RO membranes being discarded annually into landfills, which is unprecedented. The current study aims to chemically convert the end-of-life membrane, followed by its performance evaluation and microbial removal efficiency on three different sources water, i.e., tap water (TW), integrated co...

Emerging hybrid technologies have better potential than conventional technology for diversifying the desalination industry, which is presently being dominated by thermal and membrane-based desalination. Notwithstanding technological maturity of processes, they remain highly energy-intensive processes certain disadvantages. Therefore, hybridization membrane holds great attention to mitigate limi...

Abstract Our previously reported exploration (Journal of Membrane Science 565 (2018) 241–253) on the differences between fouling in reverse osmosis (RO) and forward (FO), used alginate as a foulant with initial conditions that ensured starting fluxes were same. That study found for cellulose triacetate (CTA) membrane extent fouling, based analysis resistance, was greater when part FO system. He...

Ro 23-9424 is a dual-action cephalosporin with an aminothiazolylmethoxyimino-type side chain at the 7 position and fleroxacin esterified at the 3' position. The new compound has broad and potent antibacterial activity in vitro and in vivo, reflecting contributions from both the beta-lactam moiety and the quinolone moiety. In animals, the ester bond potentially could be hydrolyzed enzymatically ...

Despite of their low concentration, the impact of steroid estrogens such as estrone, 17a-estradiol, and ethinylestradiol are often more serious than other synthetic endocrine-disrupting chemicals (EDCs) because their endocrine-disrupting potency is much higher. Although their existence in waterways is of increasing concern, nanofiltration (NF) and reverse osmosis (RO) are likely to play an impo...

<p>The application of ceramic Nanofiltration (NF) membrane in brackish water treatment is increasing due to strict quality standards. Ceramic NF a widely used process and has replaced reverse osmosis (RO) membranes many applications lower energy consumption higher flux rates. This work aims study the separation performance tubular TiO2 at low-pressure (2 bar) for single tertiary salt mixt...

The low-pressure reverse osmosis (LPRO) process is a recent development of (RO) technology for the reduction in RO energy consumption and operation cost. goal this study was to investigate performance LPRO processes treatment reuse effluent discharged from brewery upflow anaerobic sludge blanket bioreactors (UASB). In study, three different commercially available membranes were tested evaluate ...
