Application of microfiltration membrane for treatment of car wash effluent by Taguchi method prediction

Abstract

In this study conditions of refinement of car wash effluent from Paniz station in omidiyeh, Khuzestan by microfiltration polyvinylidene fluoride (PVDF- MFB) membrane with pore size 0.13 micrometer by taguchi method was investigated. Taguchi method has been applied to investigate the effect of various operating parameters such as feed pressure at 3 levels (0.4, 0.7 and 1.00 bars), feed Flow rate at 3 levels (30, 40 and 50 L/h) and feed temperature at 3 levels (25, 35 and 45°C) on the permeation flux of car wash effluent in the treatment process. In addition, the effect and contribution of each pertinenet parameter on flux and the interaction among them was determined by Taguchi analysis. Results showed that the most influential factor was feed pressure. The second significant contribution was observed for the feed temperature. Feed Flow rate a low effect on permeation flux. At optimum conditions (i.e. 1.00 bar, 50 L/hr, and 45°C), the Taguchi model predicted the value of the response (the permeation flux) as 19.76 kg/m2.h, which had a good agreement with the experimental results.
