| Summary: | This study investigates the effect of additive rice husk silica and Polyethylene glycol(PEG) at different concentration on of Polysulfone (Psf) ultrafiltration (UF) membranes. The polymer membranes were prepared by a phase inversion method using Polysulfone (PSf) , N-methyl-2-pyrrolidone (NMP) as a solvent and distilled water as non-solvent. The performances of the membranes were measured in term of pure water flux by using distilled water and solute rejection at different wastewater concentration at 50%, 75% and 87.5%. The results demonstrated that the addition 2% and 3% rice husk silica give the good rejection for membranes but the best rejection was at membranes contains 3% rice husk silica where successfully do rejection of 80.5%. As a conclusion,the range between 2%-3% of rice husk silica gives the ideal composition based on the result of flux permeation and rejection. |
