Modeling of mass transport of aqueous solutions of multi-solute organics through reverse osmosis membranes in case of solute–membrane affinity: Part 1. Model development and simulation
(
Elsevier B.V.
, 2005 , Article)
A two-dimensional mathematical model is developed for transport of multi-solute liquid (aqueous) solutions through reverse osmosis membranes in which strong affinity may exist between the membrane polymer and the solutes. ...
Room-temperature development of thin film composite reverse osmosis membranes from cellulose acetate with antibacterial properties
(
Elsevier B.V.
, 2014 , Article)
A cellulose acetate thin film composite (CA TFC) membrane was developed by direct casting of CA onto an ultrafiltration membrane support. The flux through the CA TFC membrane was, as expected, inversely proportional to the ...
An overview of brine management: Emerging desalination technologies, life cycle assessment, and metal recovery methodologies
(
Elsevier
, 2021 , Article Review)
This study examines which management methods are the most recent and advanced in managing rejected brine generated from desalination plants. It also provides up-to-date information regarding the most adequate technologies ...
Organically modified nanoclay filled thin-film nanocomposite membranes for reverse osmosis application
(
MDPI AG
, 2019 , Article)
This study validates, for the first time, the effectiveness of two nanoclays, that is, cloisite (CS)-15A and montmorillonite (MNT) at the polyamide (PA) active layer in the reverse osmosis (RO) membrane. Cloisite-15A is ...
Heat powered water pump for reverse osmosis desalination
(
TechConnect
, 2016 , Conference Paper)
Current desalination techniques are typically very energy intensive: energy consumption can account for up to 70% of the desalination costs. To improve economics of water desalination plants innovative energy efficient, ...
A better understanding of seawater reverse osmosis brine: Characterizations, uses, and energy requirements
(
Elsevier Ltd
, 2021 , Article)
Before investing in any optimizing technology for the recovery and reuse of brine resources, it is of importance to study the full physicochemical characteristics of the brine. In the current study, the physicochemical ...
Functionalization of reverse osmosis membrane with graphene oxide and polyacrylic acid to control biofouling and mineral scaling
(
Elsevier B.V.
, 2020 , Article)
The polyamide reverse osmosis (RO) membrane was modified with graphene oxide (GO), followed by polymerization of acrylic acid (used as an antiscalant) for the reduction of both biofouling and mineral scaling. After ...
Effect of concentration of calcium and sulfate ions on gypsum scaling of reverse osmosis membrane, mechanistic study
(
Elsevier Editora Ltda
, 2020 , Article)
In seawater reverse osmosis, membrane scaling is one of the major issues affecting its widespread application in the desalination industry. In this paper, the effect of concentration of calcium and sulfate ions from 20 to ...
Investigating the effect of temperature on calcium sulfate scaling of reverse osmosis membranes using FTIR, SEM-EDX and multivariate analysis
(
Elsevier B.V.
, 2020 , Article)
Membrane fouling is one of the major hurdles in widespread use of seawater reverse osmosis (SWRO) in desalination industry. There are various factors that affect the inorganic fouling or scaling of Reverse osmosis (RO) ...
