Filtration studies on the performance of titanium dioxide membranes fused on porous ceramic tubes with pore diameter of 0.2 microns are reported. Solutions of sodium nitrate in deionized and tap water were studied to determine the fouling characteristics. The membranes were cleaned frequently to evaluate the efficiency of the cleaning process and to establish the degree to which the membrane returned...
Filtration studies using titanium dioxide membranes fused on porous ceramic tubes with pore diameters of 0.2 μm is reported for solutions containing sodium nitrate and solutions containing an anionic direct dye, Direct Red 2 (C.I. no. 23500). Solution pH was adjusted with dilute sodium hydroxide and nitric acid to maintain maximum solubility of all ions present in the system. Electrolyte rejections...
