Permeation of organic molecules in water and ethanol-water solutions by reverse osmosis
نویسندگان
چکیده
The permeation of different organic molecules in water solvent and in 12% ethanolwater solution by hydrophilic reverse osmosis membrane was studied. The membrane was conditioned to the ethanol-water solution before the experiments. Initially, the membrane was characterized by water and ethanol-water solutions. The permeation of four solutes (tyramine, proline, glucose and tartaric acid) showed that the solute rejections increased with permeate flux and they were than 90% in water solvent, and they were decreased significantly in presence of ethanol.

Performance 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 کاملSalt cleaning of organic-fouled reverse osmosis membranes.
Cleaning of organic-fouled reverse osmosis membranes with concentrated salt solutions has been investigated. Polysaccharides (alginate and pectin) and Suwannee River natural organic matter were used as model organic foulants. By systematically varying the chemical and physical factors affecting salt cleaning efficiency, we were able to elucidate the processes and mechanisms involved during salt...
