| Abstract: | A mass transfer model is proposed
for prediction of permeate concentration and percent rejection at different
inlet pressures and feed dye concentrations in membrane ultrafiltration. A differential
equation in cylindrical co-ordinates considering the spiral wound membrane
equivalent to a cylindrical module is derived which coupled with mass balance
and permeate flux equations are solved to yield the theoretical permeate
concentration. As the mass transfer coefficient used from literature gave high
values for predicted permeate concentration, an empirical correlation for mass
transfer coefficient was obtained based on experimental data on the dissolution
of solid in aqueous solution from the wall of a hollow cylindrical tube where
the mass transfer occurred in the boundary layer. The experimental permeate
concentrations agreed reasonably well with those predicted from the model
developed. |
