The impact of ion migration induced by an electrical field on water flux in a forward osmosis (FO) process was examined using a thin-film composite (TFC) membrane, held between two cation exchange membranes. An applied fixed current of 100 mA (1.7 mA cm-2) was sustained by the proton flux through the TFC-BW membrane using a feed of 34 mM NaCl, and a ...

Desalination, 1976
Abstract Osmosis occurs when two solutions of differing osmolar concentrations are separated by a membrane permeable to the solvent but not (or nearly not) to the solutes. The paper derives the relationship between the kinetics and design parameters of systems designed for the purpose of applying this process to problems such as agricultural water ...

Rejection of pharmaceuticals by forward osmosis membranes
Journal of Hazardous Materials, 2012Rejection of four pharmaceutical compounds, carbamazepine, diclofenac, ibuprofen and naproxen, by forward osmosis (FO) membranes was investigated in this study. For the first time, the rejection efficiency of the pharmaceutical compounds was compared between commercial cellulose triacetate (CTA) based membranes and thin film composite (TFC) polyamide ...

Concentration of lithium by forward osmosis
Hydrometallurgy, 2020Abstract As an applying potential for a part of production of lithium (Li) from salt lake brine, forward osmosis was investigated by using semi-permeable membranes, sodium chloride (NaCl) and magnesium chloride (MgCl2) as draw solutions under several operational conditions. Cellulose triacetate and thin-film composite membranes and their orientations

Biofouling in forward osmosis and reverse osmosis: Measurements and mechanisms
Journal of Membrane Science, 2015Abstract We have investigated biofouling behavior in forward osmosis (FO) and reverse osmosis (RO) membrane systems. Analysis of these two systems was done via comparison of biofilm structure and membrane permeate water flux decline. Experiments were performed using a model wastewater solution inoculated with Pseudomonas aeruginosa in laboratory ...

Design methodology for forward osmosis system
Environmental Science and Pollution ResearchForward osmosis (FO) is an emerging process in the field of water/wastewater treatment. Water treatment using the FO process will address the ongoing problem of water scarcity. The commercial application of the FO system is very limited due to several issues like low water flux, concentration polarization, draw solution availability and regeneration ...

Recent developments in forward osmosis: Opportunities and challenges
Journal of Membrane Science, 2012Abstract Recently, forward osmosis (FO) has attracted growing attention in many potential applications such as power generation, desalination, wastewater treatment and food processing. However, there are still several critical challenges, including concentration polarization, membrane fouling, reverse solute diffusion and the need for new membrane ...

Forward osmosis: understanding the hype
Reviews in Chemical Engineering, 2015AbstractThe scientific interest in forward osmosis has increased dramatically over the last decade. The hype has resulted in a high scientific production, but research activities seem to go in all directions, and the real benefits of the process are not always well understood.

Dewatering microalgae by forward osmosis
Desalination, 2013Abstract Microalgae are known to be an excellent source of biofuels, but many issues surrounding the scale and economics of their cultivation have yet to be resolved. In particular, dewatering methods, such as centrifugation and tangential flow filtration, are prohibitively energy intensive.
