Simultaneous removal of Cobalt and Nickel from simulated aqueous waste water was studied using cross flow micellar enhanced ultrafiltration. The process parameters like pH, trans-membrane pressure, feed concentration and S/M ratio was investigated. The rejection efficiency of the order of 99.5% was obtained for Cobalt and Nickel both. The permeate flux was found almost constant. The concentration polarization and gel layer formation was insignificant. The distribution coefficients of pollutant in permeate and retente was derived from the MEUF data obtained for Cobalt and Nickel. The effectiveness of MEUF was studied from micellar binding constant and loading of micelles.
