| Abstract | The protein effluent from mungbean vermicelli industry was characterized before testing the feasibility of protein separation by the ultrafiltration process. The waste was found to be an acid solution wit h pH of 4. 5-4.7, having total solid 10-11% a nd containing two major proteins with molecular weights of approximate 35, 000 a n d 52,000 in a content of 5-8% on wet weight basis. Operating parameters in cross flow ultrafiltration including transmembrane pressure, cross flow velocity and temperature were found to affect permeate flux and protein recovery yield differently. Increase of pressure resulted in an increase in flux and yield up to limiting value whereas increasing velocity or flow rate gave rise to a non-limited flux and a variable yield, on the contrary, a temperature rise caused a significant fall in flux and yield. Th e twice larger membrane pore size did not really provide any improvement . h s revealed from the experiment, the most effective pressure, cross flow velocity, temperature and membrane cutoff were 2 .0 kg/cm2 , 14 m/s, 30 <:c and 100,000 respectively . |
