Electrodialysis (ED) electrical driven membrane processes can be used to separate or concentrate low level organic pollutants with high inorganic salt content and organic material content. The feed can be industrial waste waters for treatment of food materials. The phenomena governing transport of trace organics through ion exhange membranes and me...

This paper discusses Assisted reverse electrodialysis (ARED) as a pre-desalination technique for seawater reverse osmosis (RO) for drinking water production. ARED is comparable to an additional applied pressure along the osmotic pressure in pressure assisted osmosis; a small voltage is applied in the same direction as the open cell voltage to incr...

This paper presented the possibilities of ammonia and potable water recovery from human urine through membrane distillation. Membrane distillation could offer some advantages regarding speed and efficiency over existing urine treatment technologies, specifically regarding ammonia recovery. It was shown that up to 95 m% of all ammonia present in hyd...

This PowerPoint describes work done to examine the properties governing organic pollutant transport through an Ion Exchange Membrane in a Electrodialysis desalination of complex waste streams. A series of potential organic pollutants were examined in the work....

A detailed study of water and draw solute transport through FO membranes is presented. Flux tests were performed using CTA and TFC membranes in both orientations using four draw solutes (NaCl, Na2SO4, MgCl2, MgSO4). Fluxes were modeled using a novel model and using an FO-only approach. The membrane permeability coe-cients and structural parameter w...

Ion-exchange membranes can be used in different applications and sectors, from seawater desalination to selective separation in industrial water treatment. However, the transport of organics, and potential contamination of produced water streams, in ion-exchange membranes has not been studied thoroughly yet. This research looks into the effects of ...
