Abstract

Polymeric porous membranes are generally prepared by the phase separation of polymer solution. In this work, hollow fiber membrane was prepared by nonsolvent induced phase separation (NIPS). Effect of addition of surfactant Tetronic on the performance and characteristic of resulting membrane were investigated. The control PES membrane has the highest water contact angle, indicating the lowest hydrophilic. With addition of surfactant Tetronic in the polymer blend hollow fiber membrane, the water contact angle decreased indicates that the membrane surface is more hydrophilic. Scanning electron microscopy (SEM) images for all of the membrane showed the structure of fiber with finger-like macrovoids through the cross-section. The sponge-type of structure in the center path of original membrane was disappeared with addition of Tetronic. Ultrafiltration experiment results showed that water permeability was increased with addition of surfactant Tetronic. According to the characteristics of resulting membrane such as hydrophilicity, ultrafiltration performance, and pores structure, surfactant Tetronic was a good additive to produce hydrophilic membrane for drinking water application.

Abstract

Membran bertekanan rendah dengan ukuran pori 0,01- 10 mm mampu menghilangkan suspended solid, minyak, bakteri, dan berbagai impuritis lainnya dari air baku. Hasil penelitian diperoleh adanya pengaruh tekanan operasi, kondisi pH, konsentrasi SS, dan periode operasi terhadap kinerja proses membran mikrofiltrasi. Efisiensi penyisihan Escherichia coli maksimum diperoleh 99,996% pada tekanan operasi 1.00 Kg/Cm2; 99,999 % pada pH 6; dan 99,998 % pada SS 100 mg/L. Fluks maksimum diperoleh sebesar 82,032 L/m2jam pada tekanan operasi 1,25 Kg/Cm2; 68,074 L/m2jam pada pH 2; 65,250 L/m2jam pada SS sebesar 20 mg/L.
