Abstract

This study investigates the effect of Sodium Chloride (NaCl) coagulant medium with different concentration to produce Polysulfone (PSf) ultrafiltration (UF) asymmetric membrane. The polymer membrane prepared by a phase inversion method using Polysulfone (PSf) as a base polymer, Polyethylene glycol (PEG) 400MW as copolymer additive, N-methyl-2-pyrrolidone (NMP) as solvent and NaCl coagulant medium with different concentration as nonsolvent. In this work, the concentration of immersion medium for membrane phase immersion process prepared based on different coagulation concentration medium NaCl was modified repeatedly in the range of 1-5%. These membrane performance were analyzed via pure water permeation and solute rejection of humic acid. Based on these results, the membrane immersed in 4% concentration of NaCl coagulant medium showed the highest pure water permeation (235.69 l.m-². h-¹) and solute rejection of humic acid which is up to 98%.
