Solute coupled diffusion in osmotically driven membrane processes.
Forward osmosis (FO) is an emerging water treatment technology with potential applications in desalination and wastewater reclamation. In FO, water is extracted from a feed solution using the high osmotic pressure of a hypertonic solution that flows on the opposite side of a semipermeable membrane; however, solutes diffuse simultaneously through the membrane in both directions and may jeopardiz...
متن کاملBidirectional permeation of electrolytes in osmotically driven membrane processes.
Osmotically driven membrane processes (ODMP) are emerging water treatment and energy conversion technologies. In this work, we investigated the simultaneous forward and reverse (i.e., bidirectional) solute fluxes that occur in ODMP. Numerous experiments were conducted using ternary systems (i.e., systems containing three distinct ions) and quaternary systems (i.e., systems containing four disti...
متن کاملOsmotically and thermally driven membrane processes for enhancement of water recovery in desalination processes
Osmotically-driven membrane processes, including forward osmosis (FO) and pressure retarded osmosis (PRO), are emerging technologies that have come under renewed interest and subjected to numerous investigations in recent years. In FO, water is extracted from a feed solution utilizing the high osmotic pressure of a concentrated draw solution (DS) that flows on the opposite side of an FO membran...
متن کاملOsmotically driven flows in microchannels separated by a semipermeable membrane.
We have fabricated lab-on-a-chip systems with microchannels separated by integrated membranes allowing for osmotically driven microflows. We have investigated these flows experimentally by studying the dynamics and structure of the front of a sugar solution travelling in 200 microm wide and 50-200 microm deep microchannels. We find that the sugar front travels at a constant speed, and that this...
متن کاملStimulation of Arginine Transport in Osmotically Shocked
Cold osmotic shock treatment of early stationary phase Escherichia co2i W cells reduced the capacity for arginine uptake and accumulation by about 25%. DEAE-cellulose chromatography of the shock fluid separated four proteincontaining fractions having relatively specific argininebinding activity. The reduced transport activity of shocked cells was partially restored by two of these purified prot...
