چکیده:

In this study a hydrophilic FT-30 polyamide membrane was employed for investigation of filtration mechanism for industrial waste water treatment. Hermia blocking laws were developed to analyze membrane fouling and filtration behavior. This procedure is based on the data collected from the filtration experiments. The specific rsistance of the cake can be calculated from the slop of t/V versus V. The calculated values of the specific resistance are average values over the whole of the deposited layer on the membrane surface. The characteristics of the cake layer depend on the nature of the foulant and operating conditions. The investigation of cake layer type has a potential utilization for fouling minimization.
