Optimization the annealling time of membrane PSF19%DMF for palm oil mill effluent treatment

Abstract

The membrane that produced is expected to be used for separation the particles that having size of 0.01 to 0.1 μm with MWCO range of 200-300 from the solution as industries wastewater. The objective of research is to study the influence of the annealling time in wastewater treatment processing especially for POME and explore the membrane PSf19%DMF with optimum performance for this case. The performance of membrane is defined by three parameter as flux, permeability, and rejection. Interest gained from this study is to examine the influence of membrane PSfDMF19% in the process of wastewater treatment with membrane module which have optimum performance in the Palm Oil Mill Effluent (POME) treatment. The first step of this research is constructing of membrane PSf19%DMF with annealing temperature of 70 0C and for variance time annealing 45 minutes, 90 minutes and 135 minutes. Then follow for testing the performance of membrane PSfDMF19% with the variation pressure of 0.5; 1.0; 1.5; 2.0 and 2.5 psia then feed POME is passed through the cell Membrane ultrafiltration/nanofiltration. Optimum membrane obtained from the POME treatment contained in the membrane PSf19%DMF with annealling time optimum 90 minutes. The optimum operating conditions of the treatment for POME contained in P = 2,5Psia with the flux of 1646.0250 x 10-5 cm3 / cm2.det, pure water permeability coefficient of 156.6 x 10-5 cm3 / cm2.det. psia, and rejection 97.2703%. while the optimum pressure at P=2,5 Psia with pH = 7.42; TSS = 123mg / L; BOD = 148mg / L; and COD = 305mg / L. The results obtained is quite effective, because it have been approached with the standard effluent for POME.
