Nanofiltration (NF), as a selective Mg(II) and Ca(II) separation and concentration treatment, and electrodialysis with bipolar membranes (EDBM) were evaluated for the valorization of seawater desalination reverse osmosis brines (60 NaCl/L) to produce both rich Mg(II) and Ca(II) brines for phosphate r

Biofouling may lead to severe operational challenges that can significantly impair membrane desalination processes. In recent years, copper-based nanoparticles (Cu-NPs) have gained increased attention as a potentially viable anti-biofouling agent in membrane processes, due to their strong antibacteri

Antiscalants have been used to inhibit the formation of scales and reduce the risk of membrane scaling. However, issues such as the increased of biofouling tendency and contradictory observations of organic fouling propensity under the influence of antiscalants have been reported by other researchers

Seawater desalination reverse osmosis, SWRO, is expected to be a promising process to solve the problem of water scarcity. However, higher cost-effectiveness and less energy consumption are required for SWRO plants. Forward osmosis, FO processes using the comparable permselective membranes same as R

Based on the high heat transfer performance of heat pipe (HP) and large specific surface area of small diameter droplets, HP and spray technologies are combined in a novel single stage vacuum evaporator and artificial seawater with 3% saltness is studied experimentally. Parametric studies are carried

A new multi-effect solar desalination system based on humidification–and dehumidification (HDH) process was investigated experimentally in this paper. Several hourly yields with operation temperatures were tested and analyzed. The warm saline water is sprayed upon the porous ball humidifiers, which is

Exergetic analysis of a 2250 gpm brackish water desalination plant in California was performed using its operational data. The plant contains nanofiltration, reverse osmosis and electrodialysis reversal units subject to the same source water. The correct definition of exergetic efficiency for such syst

In this paper, a seawater reverse osmosis desalination plant with various energy recovery systems is studied using exergy analysis. These energy recovery devices include turbines and pressure exchangers as well as infinite area based single and two-stage pressure retarded osmosis units. The appropria

i n f o A customised simulation tool was used to estimate the SEC for RO and FO desalination by considering the effect of different process variables and UF pretreatment step. Using a CAPE-OPEN interface standard for running Matlab scripts in ASPEN, this modelling approach provided a flexible tool fo

We systematically evaluated the effects of operating conditions on biofouling behaviors in reverse osmosis (RO) membrane processes. The biofouling experiment was performed by filtrating nutrient-containing feed water with a cross-flow cylindrical membrane cell through a circular polyamide RO membrane
