Water treatment of brilliant green using the modified ceramic microfiltration membranes

High efficiency of the water treatment of the cationic dye (brilliant green) by using domestic ceramic microfiltration tubular membranes modified by clay mineral has been shown. The highest dye retention coefficient (99.9%) in water by such membrane was observed during the water treatment at the initial brilliant green concentration of up to 30.0 mg/dm(3) under the working pressure of 0.5 MPa. In these conditions the specific capacity of membrane amounted to 0.07 m(3)/(m(2) h).
