Forward osmosis

Seawater desalination reverse osmosis, SWRO, is expected to be a promising process to solve the problem of water scarcity. However, higher cost-effectiveness and less energy consumption are required for SWRO plants. Forward osmosis, FO processes using the comparable permselective membranes same as R

i n f o A customised simulation tool was used to estimate the SEC for RO and FO desalination by considering the effect of different process variables and UF pretreatment step. Using a CAPE-OPEN interface standard for running Matlab scripts in ASPEN, this modelling approach provided a flexible tool fo

A polyamide thin-film composite (TFC) forward osmosis (FO) membrane was fabricated and compared to a commercially available cellulose acetate (CTA) membrane for treating shale gas drilling flow-back fluids (SGDFs). The polyamide TFC membrane outperformed its CTA counterpart in terms of pure water flux a

• Shell-side TFC hollow fiber for FO was fabricated. • Polyacrylonitrile was used as the support polymer material. • Different pore structures of fibers were considered by altering the fabrication technique. • Our best membrane exhibited a structural parameter of ~300 μm. In this work, we investigated

• Life cycle assessment of engineered osmosis and osmotic dilution are performed • Environmental impacts of forward osmosis can be competitive with deep well disposal • The cost of FO can be significantly lower (up to 60%) than deep well disposal • FO energy demand with no upstream pretreatment is a

Brackish water desalination is a common method for fresh water supply in arid areas. Concentrated brine is the major waste stream generated from the desalination process. The current study proposes a multi-stage Nanofiltration (NF)–Forward Osmosis (FO)–Brackish Water Reverse Osmosis (BWRO) system to

Reverse osmosis concentrate (ROC) produced in water reclamation and desalination plants can endanger the environment if it is not treated before discharge. Volume minimisation of ROC can help in its easy disposal. The study examined the use of forward osmosis (FO) with and without granular activated

In this study, a bench scale forward osmosis (FO) process was operated using two commonly available FO membranes in different orientations in order to examine the removal of foulants in the coal seam gas (CSG) associated water, the water flux and fouling behaviours of the process were also investigat

Forward osmosis (FO) has been extensively investigated in the past decade. Despite significant advancements in our understanding of the FO process, questions and challenges remain regarding the energy efficiency and current state of the technology. Here, we critically review several key aspects of the

Produced water management is one of the key challenges faced by the oil and gas industry globally. Specifically, the gas industry in Qatar is challenged to minimize the produced/process water (PPW) volumes injected into disposal wells to ensure long term sustainability of the reservoirs.
