Stimuli-responsive polymer hydrogels as a new class of draw agent for forward osmosis desalination.
Ionic polymer hydrogels with thermal responsive units are found to induce higher water permeation rates in the osmosis process, and higher water release rates under a combination of pressure and thermal stimuli. These hydrogels have the potential for use as draw agent in forward osmosis desalination.
متن کاملMulti-layer temperature-responsive hydrogel for forward-osmosis desalination with high permeable flux and fast water release
The development of forward-osmosis (FO) desalination is significantly restricted by the lack of suitable draw agents for both high permeable flux and fast release of water. In order to address this bottleneck, a multi-layer temperature-responsive hydrogel based on poly(N-isopropylacrylamide-co-sodium acrylate) (P(NIPAAm-coSA)) was developed. The drawing layer had a high concentration of polyele...
متن کاملPerformance of Potassium Bicarbonate and Calcium Chloride Draw Solutions for Desalination of Saline Water Using Forward Osmosis
Forward osmosis (FO) has recently drawn attention as a promising membrane based method for seawater and brackish water desalination. In this study, we focus on the use of calciun chloride (CaCl2) and potassium bicarbonate (KHCO3) as inorganic salt draw solution candidates due to their appropriate performance in water flux and reverse salt diffusion as well as reasonable cost. The experiments we...
متن کاملForward osmosis: Novel desalination of produced water and fracturing flowback
Treatment and reuse of oil and gas (O&G) production wastewater in a cost-effective and environmentally sound manner is critical for sustainable industrial development and for meeting stringent regulations. High salinity, free and emulsified hydrocarbons, silts and clays released from producing formations, and process additives common in O&G drilling wastewater render many conventional treatment...
متن کاملHigh performance thin-film composite forward osmosis membrane.
Recent studies show that osmotically driven membrane processes may be a viable technology for desalination, water and wastewater treatment, and power generation. However, the absence of a membrane designed for such processes is a significant obstacle hindering further advancements of this technology. This work presents the development of a high performance thin-film composite membrane for forwa...
