The forward osmosis (FO) process was suggested as a pretreatment to multi-stage flashing (MSF) plant reduce the environmental impact of brine discharge and chemicals used. Yet, there is no study investigating performance FO MSF using tertiary sewage effluent (TSE) feed solution. Combining with TSE generates considerable permeation flux, reducing membrane area capital cost. This evaluated for in...

Forward osmosis (FO) is a promising technology for water treatment, but its fouling mechanisms are poorly understood compared to other membrane-based processes. This study focuses on combined caused by alginate (SA) and TiO2 nanoparticles, which serve as representative organic inorganic foulants, respectively. The results show that the co-presence of can effectively mitigate membrane SA under v...

Polymeric filtration membranes could be a cost-effective alternative to cation exchange (CEMs) in electrolysis with contained anolyte and saltwater catholyte because they size selectively hinder salt ion transport between compartments while facilitating proton hydroxide transport. Optimizing membrane performance requires better understanding of properties that impact electrical resistances rete...

Model-based control and monitoring such as feed-forward/feedback control, fault detection and isolation (FDI), and fault-tolerant control (FTC) techniques that utilize Lyapunov-based control laws are implemented on a high recovery reverse osmosis desalination plant model. A detailed mathematical model of a high recovery reverse osmosis plant is developed. This model incorporates the large spati...

Osmosis is the movement of solvent across a membrane induced by a solute-concentration gradient. It is very important for cell biology. Recently, it has started finding technological applications in the emerging processes of Forward Osmosis and Pressure-Retarded Osmosis. They use ultrathin and dense membranes supported mechanically by much thicker porous layers. Until now, these processes have ...

Osmotically driven membrane processes (ODMP) have gained renewed interest in recent years and they might become a potential solution for the world's most challenging problems of water and energy scarcity. Though the concept of utilizing osmotic pressure difference between high and low salinity streams across semipermeable membranes has been explored for several decades, lack of optimal membrane...

• FO-MD process can yield a high water quality for most of the AD effluents. Obtained fluxes < 2 Lm ?2 h ?1 are too low industrial application at present. The energy consumption was 100 times less than electricity produced. cost produced by system 1.29 $ m ?3. For to be efficient, flux must exceed 14 ?1. Despite potential forward osmosis (FO) and membrane distillation (MD) treat difficult waste...

Forward osmosis (FO) is an emerging low energy membrane-based technology and can be applied if the diluted draw solution (DS) directly utilized without additional recovery/treatment. In this study, FO process was for treatment of textile industry wastewater using fertilizer as DS. This paper focuses on modelling optimisation machine learning techniques like Response Surface Methodology (RSM), A...
