Abstract

Abstract. The effect of bentonite as filler on the performance of the composite membrane of PVDF-PMMA has been performed. This study was conducted to determine the performance PVDF-PMMA composite membranes and membrane applications PVDF-PMMA-Bentonite on oily wastes. Bentonite is obtained from North Aceh while PVDF membrane-PMMA by phase inversion method. This study uses an oily waste water model was made by mixing surfactant tween 80 with concentration of 2% with palm oil and gas oil. Membrane PVDF-PMMA-Bentonite is analyzing using cell ultrafiltration (flux test), FTIR and SEM-EDX. The results showed that the value of flux with the addition of bentonite is greater than without bentonite. Good flux values contained in the PVDF-PMMA-Bentonite (1:1:2) amounted to 32.143 L/m2.h.bar with permeability of 21.428 L/m2.h. FTIR characterization analysis results show that bentonite can add to pore at wave number 1520 cm -1 and 1660 cm-1 SEM and EDX results showed regular shape and uniform pore.

Summary

INTRODUCTION

Some polymers such as polyethylene oxide (PEO), polyacrylonitrile (PAN), Membrane technology is broadly used for polydimethylsiloxane (PDMS), and polymethyl drinking water desalination, waste cooking oil methacrylate (PMMA) have been used as processing, medical purposes, and gas PVDF matrix mix [4]. The most important point is that membrane does PMMA membrane was conducted by not have negative impact to the environment Ochoa et al.,[3] They investigated the because separating process by using membrane hydrophilicity effect to the separation of oil does not need additional chemical compound. The high crystallinity of PVDF can be PVDF-PMMA membrane by adding bentonite decreased through blending method which is a as a filler is still researcher’s choice to increase simple method to modify the polymer matrix. Filler is used to Effect Of Bentonite As Filler In Composite Membrane Performance Polyvinylidene Fluoride(Pvdf)... In order to support it, this research concerns on developing PVDF-PMMA composite membrane by adding the bentonite as the filler. The addition of bentonite is expected to increase the membrane’s performance resulting high flux value and rejection coefficient. This research is an effort in creating a technology for solving the separation problem in low-cost and easy way as well as without further impact [6]
