Forward osmosis: Definition and evaluation of FO water transmission coefficient

Journal of Water Process Engineering, 2017
Abstract Forward Osmosis (FO) usually has a measured water flux (Jw,exp) much smaller than its theoretical water flux (Jw,theoretical); the discrepancy between Jw,exp and Jw,th increases at a higher theoretical osmotic pressure difference (Δπtheoretical).

Highly hydrophilic thin-film composition forward osmosis (FO) membranes functionalized with aniline sulfonate/bisulfonate for desalination

Journal of Membrane Science, 2018
Appropriate membranes are crucial to maximize the potential of forward osmosis (FO) in water treatment. In this study, high-performance and well-constructed thin-film composite (TFC) FO membranes were developed via chemical modifications for FO ...

Potentialities of thermal responsive polymer in forward osmosis (FO) process for water desalination

Desalination, 2021
Abstract This work aims at assessing the technical feasibility and performances of the Forward Osmosis (FO), an emergent desalination process. Two FO processes with different draw solutions have been studied: the first one is based on Ammonium Bicarbonate (AB) and the second on poly (propylene glycol-ran-ethylene glycol) monobutyl ethers (PAGBs) with

Hydroacid complexes: a new class of draw solutes to promote forward osmosis (FO) processes.

Chemical Communications, 2013
A new class of draw solutes from hydroacid complexes is presented. With hydroacid complexes as draw solutes in FO, superior performance is achieved in terms of high water fluxes and negligible reverse solute fluxes. The characteristics of expanded configurations, abundant hydrophilic groups and ionic species are essential for hydroacid complexes as ...

NOM and TEP fouling of a forward osmosis (FO) membrane: Foulant identification and cleaning

Journal of Membrane Science, 2012
Abstract The study of forward osmosis (FO) membranes has increased due to the already demonstrated advantages compared to high-energy membrane processes such as reverse osmosis (RO). This research focuses on characterization of the natural organic matter (NOM) fraction causing fouling on the active layer (AL) of a FO membrane in a novel plate and ...

The forward osmosis-pressure retarded osmosis (FO-PRO) hybrid system: A new process to mitigate membrane fouling for sustainable osmotic power generation

Journal of Membrane Science, 2018
Pressure retarded osmosis (PRO) is an emerging technology to harvest the renewable salinity-gradient energy. However, its performance can be significantly limited by severe membrane fouling if a real waste effluent is used as the feed solution. To tackle
