Forward osmosis (FO) membranes have gained interest in several disciplines for the rejection and concentration of various molecules. One application area for FO membranes that is becoming increasingly popular is the use of the membranes to concentrate or dilute high value compound solutions such as pharmaceuticals. It is crucial in such settings to control the transport over the membrane to avo...

Osmotic actuation is a ubiquitous plant-inspired actuation strategy that has a very low power consumption but is capable of generating effective movements in a wide variety of environmental conditions. In light of these features, we aimed to develop a novel, low-power-consumption actuator that is capable of generating suitable forces during a characteristic actuation time on the order of a few ...

Livestock wastewater contains a large amount of nutrients that are available for recovery. In this study, a proof of concept process based on Forward Osmosis (FO) was proposed and investigated for in-situ formation of struvite from digested swine wastewater. This FO system took advantage of a drawback reverse solute flux (RSF) and used the reversed-fluxed Mg for struvite precipitation, thereby ...

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...

Forward osmosis (FO) technology has been applied for removal of chromium (Cr) from water environment. Comparison the efficiency Cr(VI) and Cr(III) was investigated by changing several operational conditions. The pH feed solution plays an important role in rejection Cr. increased with increasing pH, while stable. It also demonstrated that Cr higher when membrane active layer faces compared to dr...
