Abstract
Membrane is an alternative technology of water treatment with filtration principle that is being widely developed and used for water treatment. The main objective of this study was to make an asymmetric membrane using cellulose acetate (CA) polymer and sewage sludge ash (SSA) by dry-wet phase inversion method in various proportions of CA/SSA (17.5/0, 15.75/1.75, 14 /3.2, 12.25/5.25 and 8.75/8.75g). Characterization of prepared membranes was performed such as water content, IR analysis and Scanning electron microscope (SEM). Also, the possibility of solute rejection of nickel ions from wastewater using Sludge membrane (SM) was evaluated by different parameters as pH value (2-10) and contact time from (0 to 30 min). Results reported that the best performance of CA/SSA blend membranes at 8.75/8.75g. Adsorption isotherm studies indicated that Freundlich model described the experimental data with R2 values greater than 0.985.
