As a membrane separation technology forward osmosis (FO) was operated by the natural osmotic pressure difference between low-concentrated feed solution and high-concentrated draw solution to drive water but prevent most solutes across a semi-permeable membrane [1 2] Since the last decade the applications of FO included but are not limited to wastewater purifying [3 4] brackish water and
We report the use of highly porous Janus membranes with unparalleled forward osmosis (FO) performance in terms of water flux and reverse salt flux A porous Janus FO membrane composed of a hydrophilic cellulose acetate layer and a hydrophobic polyvinylidene fluoride (PVDF) nanofiber layer was fabricated by electrospinning
During the DCMD test the Janus membrane showed an improved permeate flux with the increasing deposition time and operation temperature and the flux improvement was up to 120% for the Janus membrane deposited for 6 h with 80 C feed On the other hand the Janus membrane also exhibited a high salt rejection and good long-term stability in
The Journal of Membrane Science provides a focal point for academic and industrial chemists chemical engineers materials scientists and membranologists working on membrane systems The journal publishes original research and reviews on membrane transport membrane formation / structure fouling module / process design and processes / applications
Forward osmosis (FO) has gained increasing attention in desalination wastewater treatment and power generation However biofouling remains a major obstacle for the sustainable development of the FO process Both passive and active strategies have been developed to mitigate membrane biofouling A comprehensive understanding of different strategies and mechanisms has fundamental significance

Recovery of Osmotic Power in SWRO Plants The paper analyzes the ways that different researchers have selected to overcome the phenomenon of CP and presents an overview of the existing RO membranes from the point of view of their suitability for use in Forward Osmosis power generation
Fluid Technology Solutions (FTS) is a water treatment company applying innovative and proven solutions to the most challenging wastewaters FTS focuses on forward osmosis (FO) membrane research and development manufacturing and membrane system engineering and design to provide innovative solutions for its corporate industrial and municipal
Membrane distillation (MD) is a thermally driven separation process in which separation is driven by phase change A hydrophobic membrane presents a barrier for the liquid phase allowing the vapour phase (e g water vapour) to pass through the membrane's pores The driving force of the process is a partial vapour pressure difference commonly triggered by a temperature difference
Koch Membrane Systems Launches TIDAL™ Forward Osmosis Solution Enables Product Concentration Without Heat 04 April 2019 Wilmington MA – April 4 2019 — Recognizing a need for a natural heatless concentration process that preserves product quality Koch Membrane Systems (KMS) announces the launch of TIDAL Forward Osmosis Solution an
The concept of an osmotic microbial fuel cell (OsMFC) was proposed in 2011 [] In an OsMFC a forward osmosis (FO) membrane acts as a separator between the anode chamber with wastewater and the cathode chamber full of draw solution [1 2 3 4 5 6] Specifically the concentrated organic contaminants in the anode chamber by the FO membrane are oxidized with the production of bioelectricity and
Membrane technology using organic and inorganic membranes exhibits potential for treatment of oily-wastewater feeds having high TDS The low energy requirement of membrane-based technology is attractive Reverse osmosis (RO) has been used to treat PW with TDS in the range 500–25 000 mg/L
