Optimal operating conditions of micro- and ultra-filtration systems for produced-water purification: Taguchi method and economic investigation
, Article Desalination and Water Treatment ; Volume 57, Issue 42 , Oct , 2015 , Page 19642-19654 ; 19443994 (ISSN) ; Mashhadi Meighani, H ; Sharif University of Technology

Abstract
In this study, treatment of two real produced waters was studied using microfiltration (MF) and ultrafiltration. In the first step, the effects of operating parameters including temperature, transmembrane pressure (TMP), cross-flow velocity (CFV), and back pulse time (BPT) (in the MF system) at three levels on the amount of permeate flux were investigated using ceramic and polymeric membranes. To design the experiments and optimize the experimental results, the L9 (34) and L9 (33) orthogonal arrays of the Taguchi method and a response category of the-larger-the-better were applied. Analysis of variance was used to determine the most important parameters affecting the permeate flux. The...
