    Abstract

    Response surface methodology (RSM) is a collection of statistical design and numerical optimization techniques used to optimize processes and product design. RSM was performed to optimize in preparing the best composition of polyvinylidene fluoride (PVDF) composite membranes. Quartic model was used to analyzed the optimized results. Preparation of PVDF composite membranes was studied by introducing nano particles additives, which include nonsolvents (water and glycerol) and inorganic salt (LiCl) in varied compositions. Dimethylacetamide (DMAc) was used as a solvent. Distilled water was used as an internal coagulant, while a mixture of water and glycerol was used as external coagulant. The prepared PVDF hollow fiber membranes ultrafiltration were characterized in terms of permeate flux. Average pore size and effective surface porosity were determined using the water permeation method for the dried membranes. The cross sectional structure of hollow fiber membranes were examined by field electrostatic scanning electro microscopy. Results from RSM showed that the highest flux of 145.37 L/m2h was achieved with optimum condition of .aeration flow rate, hydraulic retention time, mixed liquor suspended solid concentration of 2.25 ml/min, 276.93 min, 4.50 g/L at maintained pH of 6.50.
