Abstract
Membrane technologies grow rapidly in the world and were applied in many industrial processes as an efficient separation technique and for the purpose of wastewater treatment. Membrane separation process was used to replace the conventional method to reduce time of operation, reduce space requirement for downstream process and increase the productivity. There are several types of membrane separation used in the industries which are ultrafiltration, microfiltration, nanofiltration and reverse osmosis. These membrane separations used different types of membrane such as flat sheet, hollow fiber and other. Even though membrane separation has many advantages, it also has a problem which is membrane fouling that resulting in reduces permeate flux and increase the production cost. This study is undertaken to identify and determine the resistances that lead membrane fouling by using Resistance-In-Series Model and Darcy’s Law. A cross-flow filtration with polysulfone hollow fiber membrane of molecular pore size 0.2μm was used to separate the buffer solution containing Escherichia coli. From the data obtained, the weak adsorption resistance was explored as the main factor resulting membrane fouling in this study. For the membrane recovery, the alkaline cleaning can recover the fouled membrane about 99.8% and it could help increasing the permeate flux for separation process. E. coli K-12 strain was identified which can give high permeate flux compared to E. coli B strain. Thus, E. coli K-12 can be retained by membrane in the separation of succinic acid from fermentation broth.
