Abstract

Water is the most valuable resource today. The very high demand for clean water makes the world of technology a challenge in the technology world to make technological and material updates in carrying out water filtration processes that are more cost-effective but have a better level of efficiency and effectiveness than before. The test materials used were membranes with polymers made of polyetherculphons with concentrations of 27.5, 30, and 32.5wt% and titanium dioxide reinforcing agents with concentrations of 2wt% as well as marine additives N.N Dimethlformamide. The method used is the membrane formation method with phase inversion method. The method used was the phase inversion method in which the polymer, reinforcement, and solvent used were mixed homogeneously for approximately 2-3 hours and the membrane was directly printed on a glass plate. Three tests were conducted for membrane formation namely tensile test, microscopic test using scanning electron microscope, and flux value test using clean water permeability (CWP). Membranes show the higher the polymer concentration value will increase the tensile stress value on the membrane. In microscopic testing, the higher the membrane concentration, the greater the pore density formed on the membrane surface. In the CWP test, the highest flux values at the membrane were shown in PES membranes with concentrations of 27.5wt% compared to concentrations of 30wt% and 32.5wt%. This study concludes that membrane expansion by increasing the concentration of polyethyrephones at concentrations of 27.5wt%, 30wt% and 32.5wt% and 2wt% titanium can increase the tensile stress and pore density on the membrane surface. The resulting flux values were smaller at a concentration of 32.wt% compared to the concentrations of 30wt% and 27.5wt%.
