• CHP–H2CO3 is a high osmotic pressure thermolytic draw solute. • CHP–H2CO3 solutions produce relatively high forward osmosis water fluxes. • Low grade heat should be sufficient to degas CHP–H2CO3 solutions. • CHP–H2CO3 solutions display good material/membrane compatibility. • Water flux and reverse dr

Global water planners are increasingly considering seawater desalination as an alternative to traditional freshwater supplies. Since desalination is both expensive and energy intensive, taking advantage of favorable natural and societal conditions while siting desalination facilities can provide sig

This study focuses on the water quality assessment (feed, product and brine) of the pilot adsorption desalination (AD) plant. Seawater from the Red Sea is used as feed to the AD plant. Water quality tests are evaluated by complying the Environmental Protection Agency (EPA) standards with major prima

Forward osmosis (FO) has recently attracted growing attention in wastewater, brackish groundwater and seawater desalination, and power generation. This study evaluates the potential of using a batch laboratory-scale FO system as a pre-treatment for the reverse osmosis (RO) process. FO is a low press

A new configuration of electrodeionisation with a bipolar membrane (EDI-BP) with a segment electrode was proposed for the treatment of simulated dilute Ni2+-containing wastewater. The feasibility of EDI-BP was analysed and experimentally validated, and its current density distribution was studied sim

− Electrodialysis has an advantage in concentrate treatment because the waste concentration factor increases linearly with removal ratio, Sodium concentration (mg/L) Calcium concentration (mg/L) Chloride concentration (mg/L) resistance of 2 Ω·cm2, the resistance from two membranes would represent 14

Produced water from unconventional gas and oil extraction may be hypersaline with uncommon combinations of dissolved ions. The aim of this analysis is to aid in the selection of produced water treatment technology by identifying the temperature, pH, and recovery ratio under which mineral solid forma

Concentrate streams from industrial processes entail an important risk for the environment, as they are often discharged into it. Therefore, efforts must be made to reduce the load of contaminants discharged to the environment. Eutectic freeze crystallization (EFC) is a novel technique which allows

In this study, a methodology is developed to assess the feasibility of a reverse osmosis (RO) desalination system powered by a stand-alone salinity driven pressure retarded osmosis (PRO) technology. First, the proposed hybrid RO–PRO system is analysed as a thermodynamic cycle and its feasibility is

• Highly impaired liquid streams can be sustainably treated by forward osmosis. • Forward osmosis treatment of drilling mud and produced water was evaluated. • Water recovery N 70% was achieved in pilot and demonstration scales. Forward osmosis is a suitable and effective process for treatment of di
