Abstract

The presence of pharmaceutical wastewater can pose significant challenges to the environment. Since conventional Wastewater Treatment processes are not efficient for the complete separation of drug materials, solvent extraction through a hollow Fiber Membrane Contactor could be a promising alternative. In this study, a developed polysulfone (PSF) hollow fiber membrane was fabricated using a non-solvent phase separation (NIPS) method to extract penicillin G from aqueous solutions in the membrane contactor system. From the characterization experiments, the prepared polysulfone membrane demonstrates an outer surface contact angle of 69.6°, critical water entry pressure (CEPw) of 250 kPa, total porosity of 72.2%, and collapsing pressure of 500 kPa. The extraction of penicillin G from the aqueous phase was performed with a 5% w/w solution of Aliquat 336. The effect of the operating parameters on the extraction flux of penicillin G was investigated using the response surface method (RSM). The optimum penicillin G flux of 1.46×10-3 kg/m2s was found at an operating pressure of 100 kPa, an aqueous phase flowrate of 70.5 ml/min, and an organic phase flowrate of 200 ml/min. Therefore, the developed PSF hollow Fiber Membrane Contactor can be considered a proper choice to remove antibiotics (penicillin G) from aqueous solutions.
