Abstract

Membrane technology has been the methods in the management of clean water, one of polymer that used as membrane materials is polyethersulfone (PES). However, PES is easy to fouling because it is hydrophobic. Fouling will cause a decrease in membrane performance. In this study, PES membrane was modified using hydrophilic additives, namely an alloy of Mg(OH)2 and chitosan. This research study the effect of additives on the performance and anti-fouling properties of the membrane. The membrane preparation was carried out using polymer blending method. The dope solution was made by mixing 18% PES with additives in the form of an alloy of Mg(OH)2 and chitosan with varying compositions of 1% and 5%, with N-methyl-2-pyrrolidone (NMP) as a solvent, and a mixture of ethanol and water as a non-solvent. The membrane characterization was evaluated by analyzing the functional groups. Membrane performance was carried out by measuring the flux and permeability of pure water, selectivity or rejection, as well as membrane anti-fouling tests. From the results of the study, the largest permeability value in PES/NMP membrane with the addition of 5% additive (membrane N5) was 12.9 L/m2.h.bar, rejection was 33.54% with good anti-fouling properties.

Abstract

Clean water is a natural resource which is indispensable, due to the increase of population, water demand is also increasing. so that technology is needed in water treatment to satisfy the needs of clean water. Membrane separation technology is a technology that has grown rapidly in addressing the problems of water treatment. The purpose of this study was to determine the characteristics and performance of Polyethersulfone (PES) membranes modified with magnesium hydroxide or Mg(OH)2 and modification using chitosan. Membrane preparation was carried out by the phase inversion method, using an 18 wt% PES polymer modified with the addition of 0.2 wt% of Mg(OH)2, and modification using 0.2 wt% of chitosan. Furthermore, it was dissolved in N-Methyl pyrrolidone (NMP) as a solvent and the dope solution was stirred for 24 hours until it was homogeneous. Membrane characterization includes functional group analysis and measurement of the membrane water contact angle. Whereas membrane performance testing is done through permeability measurement and membrane rejection using a dead end ultrafiltration module. The results showed that the hydroxyl group (-OH) contained in Mg(OH)2 and chitosan were able to improve the hydrophilicity of the PES membrane. The membrane permeability coefficient modified with Mg(OH)2 gives a value of 8.236 L/m2.h.bar, while modifying the membrane using chitosan produces a value of 6.237 L/m2.h.bar. Both of them experience an increase compared to pure PES membrane without modification that has a permeability value of 4.123 L/m2.h.bar.
