Combining two solutions of different composition releases the Gibbs free energy of mixing. By using engineered processes to control the mixing, chemical energy stored in salinity gradients can be harnessed for useful work. In this critical review, we present an overview of the current progress in salinity gradient power generation, discuss the prospects and challenges of the foremost technologi...

This paper evaluates life cycle Greenhouse Gas (GHG) emissions of a Seawater Reverse Osmosis (SWRO) desalination plant and assesses its performance under three power supply scenarios. A Life Cycle Assessment (LCA) analysis is conducted for a plant located in Perth, Western Australia (WA). Input and output flows of SWRO plant are based on literature and Perth desalination plants. The Simapro Aus...

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...

Reverse osmosis is the leading technology for desalination of brackish water and seawater, important solving growing problems fresh supply. Thermal technologies such as multi-effect distillation multi-stage flash still comprise an portion world’s capacity. They consume substantial amounts energy, generally obtained from fossil fuels, due to their low efficiency. Hybridization a strategy that se...

Seawater reverse osmosis (SWRO) membrane biofouling remains a common challenge in the desalination industry, but the marine bacterial community that causes membrane fouling is poorly understood. Microbial communities at different stages of treatment processes (intake, cartridge filtration, and SWRO) of a desalination pilot plant were examined by both culture-based and culture-independent approa...

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.
