in this paper, one of the numerical solution method of one- particle, one dimensional timeindependentschrodinger equation are presented that allows one to obtain accurate bound state eigenvalues and functions for an arbitrary potential energy function v(x).for each case, we draw eigen functions versus the related reduced variable for the correspondingenergies. the paper ended with a comparison ...

The effects of feed and draw solution temperature and transmembrane temperature difference on the rejection of 12 trace organic contaminants (TrOCs) by two forward osmosis (FO) membranes were investigated. The membrane structure parameter (S) and the reverse salt (NaCl) flux selectivity (RSFS) were constant over the temperature range of 20-40 1C, suggesting that within this range, the solution ...

This study investigated the effects of surfactant addition to draw solution on performance osmotic membrane bioreactor (OMBR). Forward osmosis (FO) tests were conducted with sodium dodecyl benzene sulfonate (SDBS), a representative surfactant, both inorganic and ionic organic solutions, including chloride (NaCl), acetate (NaOAc), propionate (NaPro), determine desirable for OMBR operation. Resul...

Forward osmosis (FO) is increasingly being studied as an alternative desalination technique to the other conventional technologies, owing primarily its low energy potential. However, co-opted limitations in draw solution (DS) regeneration stage FO processes and lack of effective DS have hampered FO's implementation for potable water application on industrial scale. In this work, we explored Don...
