Scientific domain: %scientific_domain Subject short description: Water shortage and decline of the quality of fresh water resources make sea water desalination become a major way for drinking water production. Reverse Osmosis (RO) is now the main technology used for seawater desalination, but it shows a limited recovery and the environmental impact of large volumes of rejected brines is still a...

The origin, structure, and composition of biofilms in various compartments of an industrial full-scale reverse-osmosis (RO) membrane water purification plant were analyzed by molecular biological methods. Samples were taken when the RO installation suffered from a substantial pressure drop and decreased production. The bacterial community of the RO membrane biofilm was clearly different from th...

This study aims at studying the environmental effects of desalination byproducts and the cost analysis of desalination systems. Focus was made on the two widespread techniques of seawater desalination; the Multistage Flash (MSF) System and Reverse Osmosis (RO) system. These two technologies of thermal and membrane desalination have a substantial history and their industry is well established. M...

The principle of ultrafiltration (UF) is filtration of solutions or suspensions under pressure through a semipermeable membrane. The membrane has pores that allow the solvent and small molecules to pass through and the larger molecules to be retained. Ultrafiltration may therefore be considered as both a concentration and a fractionation process according to the particular components of interes...

This manuscript investigates the supercritical carbon dioxide (sCO2) power cycle employed in block of concentrated solar (CSP) plants—solar tower—as an alternative for desalination, developed with either distillation or reverse osmosis. concept is investigated as a possible up-scaling SOLMIDEFF project, originally based on hot-air micro gas turbine combined dish collector. For upscaled concept,...

Numerous membrane fouling studies have been conducted to predict and prevent membrane fouling. It was only recently that a new parameter, TEP, was introduced in this research. The deposition of TEP on reverse osmosis (RO) membranes has already been imaged, correlations between ultrafiltration (UF) fouling and TEP concentrations have been reported. Furthermore, TEP deposition takes place in an e...

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...

The potential of membrane scaling control by a real-time optimization algorithm was investigated. effect antiscalant dosing evaluated from the induction time measured in glass batch-reactors, and operational performance lab-scale reverse osmosis (RO) unit two pilot-scale RO units. Step changes demonstrated that accumulation is ‘paused’ during periods when optimum dose applied. This paramount fo...
