This paper introduces the research about the possibility of applying microfiltration through a ceramic tubular membrane with 200 nm pore sizes to the wastewater obtained in the production process of wheat starch and vital wheat gluten. The consumption of process water would thus be reduced, the starch would be exploited better to a greater extent and the wastewater problem would consequently be solved. The second issue examined is the efficiency of the combination with sedimentation prior to the microfiltration as to reduce the occurrence of polarization layer on the membrane and to keep the wastewater permeate flux through the membrane constant as possible. The independent variables, the parameters that vary during the course of microfiltration. are the transmembrane pressure, flow rate and the wastewater sedimentation time prior to microfiltration while the dependent parameter that is constantly monitored during the process is the permeate flux. The maximum value of the permeate flux (24 lm 2h"') was achieved at three bars and at a flow rate of 150 Ih"1 after having initially allowed the wastewater to settle for four hours. Microfiltration reduces the wastewater dry matter from 11.000 mg/l to 4,000 mg/l and it also significantly decreases the values of the suspended matter, namely from 9,000mg/l to 300mg/l.
