Spinning basket membrane module is a special type of shear-enhanced device with inbuilt cleaning facility. In this article, the performance of this module has been reported in the ultrafiltration of bovine serum albumin. High permeate flux (=8.7 x 10(-5) m(3).m(-2).s(-1)) under moderate condition of transmembrane pressure (TMP) (=588.4 kPa) clearly indicates the efficacy of the design in reducing concentration polarization. A two-parameter, semi-empirical, steady-state model has also been proposed and validated under varied parametric conditions of TMP, feed concentration and rotational speed. Maximum absolute deviation between the model prediction and the experimental data was restricted only within 6%.
