Optimization of Water Permeability of “Green” Non-Woven Filter Media from Lignocellulosic Fibers Using Taguchi Method

Water permeability is often used in characterization of the filter media. This paper focuses on the evaluating the effects of the process parameters and design parameters on the permeability of filter media as an output and considered as a response and the prediction of the optimal combination of synthesis parameters with an objective of maximizing the permeability. For this purpose, the Taguchi experimental design technique, analysis of varians (ANOVA), and signal-to noise (S/N) ratio were used. In this study, only eight filter configurations of Taguchi’s L8 orthogonal design were fabricated and tested. As a result from these experiments, the filter configuration satisfying the maximum water permeability value was determined, which show that statistical analysis is a useful method to quantify filter permeability objectively.
