Description
Summary:The increasing population of living things causes the need for clean water to increase. However, water in many communities is contaminated with various foulants such as humid acid which can reduce water quality. The study aims to investigate the effect of increasing the concentration of polyvinylpyrrolidone (PVP) on pore formation in the membrane by analyzing the performance and characteristics of the resulting membranes. Membrane preparation is done by the phase inversion method, which begins with preparing a dope solution by mixing polyethersulfone (PES) 18% and adding PVP (0%, 1%, 3%, and 5% wt) then dissolved in the n-Methylpyrrolidone (NMP) solvent to reach a total solution of 100%. Membrane characterization carried out included analysis of membrane functional groups using FTIR and analysis of morphological structures using SEM. In addition, a membrane performance test was also carried out consisting of measuring water flux, permeability and membrane selectivity/rejection testing. Based on this research, it can be summarized that the addition of PVP can increase the performance of the resulting membrane. The PES/NMP/PVP membrane at a concentration of 3% wt had the highest water permeability compared to other concentrations with a value of 87.589 L/m2.h.bar.
