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 ...
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, ...
Impact of high turbidity on reverse osmosis: Evaluation of pretreatment processes
(
Desalination Publications
, 2020 , Article)
This study evaluates the performance of sand filtration (SF) and ultra-filtration (UF) as pretreat-ment processes for reverse osmosis (RO) for seawater with turbidities of 4.8, 23.2, and 99.7 NTU. For seawater with a ...
Quantifying and reducing concentration polarization in reverse osmosis systems
(
Elsevier
, 2023 , Article Review)
Reverse osmosis (RO) is an efficient water purification technique because of its high selectivity and permeability. During RO operation, rejection of solutes at the membrane surface leads to generation of a concentration ...
An overview of water desalination systems integrated with renewable energy sources
(
Elsevier B.V.
, 2022 , Article Review)
Nowadays, the growing world population, climate change, pollution, rising consumer demand, and resource exploitation have contributed to a freshwater shortage. Hence, water desalination is heavily used for freshwater ...
The development of a process simulator transport model for RO systems
(
Elsevier Ltd
, 2022 , Article)
This paper introduces solute-solvent interactions onto a universal transport modeling approach that has been recently introduced for predicting RO membrane performance. The mathematical modeling framework utilizes chemical ...
