Abstract
The filtration tests of electrolytic solutions performed with different ceramic membranes show the salt rejection depends on the pH,the salt nature and concentration. Simple correlation between streaming potential and rejection rates exits and confirms the streaming potential is a relevant parameter to characterize the surface charge of the filtering material during the filtration process.
