Karakteristik Fouling dan Folarisasi Konsentrasi pada Proses Pemurnian dan Pemekatan Karaginan dengan Membran Mikrofiltrasi

Abstract

The fouling resistance at cross flow I'eloeity 2,97, 3,47 and 3.97 m S·lwas 0,1312; 0,1741 alld 0.1758 kPa nl h r I respectively. It is not influenced by cross flow velocity and has 2-3 times greater than internal membrane resistance. Concentration polarization resistance at range cross flow velocity 2,97 to 3,97 m S·I was 0,4030 to 0,93 14 kPa nl h rl. Concentration polarization resistance is influenced by cross flow velocity, where at high cross flow velocity the concentration polarization can be reduced At /owtransmembrane pressure, total resistance is domillated by fouling resistance but at high transmembrane pressure it is dominated by r.oncentration polarization resistance. Behavior afflUX during carrageenan purification can be describedfineiy by resistance in series model,
