Osmosis is a physical phenomenon that has been extensively studied by scientists in various disciplines of science and engineering. Early researchers studied the mechanism of osmosis through natural materials, and from the 1960s, special attention has been given to osmosis through synthetic materials. Following the progress in membrane science in the last few decades, especially for reverse osm...

A new method is presented for the design and operation of wind wave-energy-powered modular seawater reverse osmosis (SWRO) desalination plants. The SWRO modules are designed to achieve discrete adaptation their power consumption estimated output renewable energy technologies. mean, mode median values proposed as statistical parameters select size single-stage modules. aim system configurations ...

New developments in pressure- and thermally driven membrane desalination technologies offer the potential to cost-effectively treat high-salinity waters, especially when powered by low-cost solar electricity thermal energy. This paper presents a comparative techno-economic assessment of state-of-the-art most promising for high recovery desalination, namely, osmotically-assisted reverse osmosis ...

BACKGROUND As an appropriate tool, membrane process is used for desalination of brackish water, in the production of drinking water. The present study aims to investigate desalination processes of brackish water of Qom Province in Iran. METHODS This study was carried out at the central laboratory of Water and Wastewater Company of the studied area. To this aim, membrane processes, including n...

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...

Graphene oxide (GO)-enhanced membranes are being developed to solve major limitations in both reverse osmosis (RO) and membrane distillation (MD) technologies, which include high electricity thermal energy consumption. This study performed, for the first time, a life cycle assessment determine effects of using GO-enhanced on environmental impacts seawater desalination via RO MD. Four scenarios ...

We developed a method for the in situ synthesis of an oligoamide coating on gold. The resultant surface chemical composition, wettability, and chemical nature were comparable to aromatic polyamide films used as reverse osmosis membranes. Hence, the oligoamide wafer may be used in adsorption/fouling studies as a surface mimetic of reverse osmosis membranes.
