Abstract

The chapter focuses on the implementation of Box Behnken Design (BBD) to increase permeate flux of rectangular sheet membrane. Box Behnken Design (BBD) was used to optimize the membrane operation by predicting the optimum conditions. The factors such as operating pressure, feed velocity, and pore size were selected as the input of the model. The study illustrates the optimum conditions of operating pressure, feed velocity, and pore size, which was found to be 14.5Pa, 0.179 m/s, and 0.59µm respectively. Analysis of variance was used to identify the significant terms in the model equation. The effect of input parameters on the model output evaluated using Pareto analysis. It shows that operating pressure is the most significant parameter in the developed model. The BBD predicted results follow the actual results with high accuracy.

Motivation And Background

The Global scarcity of water resource and rapid degradation of water quality has advocated for water reclamation and reuse(Lyu, Chen, Zhang, Fan, & Jiao, 2016). So, the membrane is widely used for water reclamation and overcoming water scarcity.

The membrane was a well-known technique since the eighteen century and implemented for water reclamation. The membrane widely used in different industries like the food industry, paper industry, and rubber industry (Mohammadi, Man, Hassan, & Yee, 2013)(Zhou, Zhao, Bai, Zhang, & Tang, 2012). Membrane separation technique are classified as microfiltration(Lim & Bai, 2003), ultra filtration(Abdessemed, Nezzal, & Ben Aim, 2000) and reverse osmosis (Sahinkaya et al., 2019)(Tong et al., 2020) and implemented to improve quality of water feed stream. Membrane attracted many researchers and environmental scientists for its ability to produce high quality of permeate with high reuse potential, but it is limited in its application for its rapid fouling tendency. Fouling is due to partial and complete pore blocking of the membrane during the separation process (Tong et al., 2020)(Liu, Wu, Hou, & Wang, 2020). To predict optimum operating factors and enhance permeate flux, Box Behnken method used in the present study.
