A protein is present in 8 m 3 of fermentation liquor at a concentration of 0 . 6 g / l . Ultrafiltration under gel
A protein is present in m of fermentation liquor at a concentration of gl
Ultrafiltration under gel polarization conditions is used to concentrate the protein by a factor of five. The gelation concentration is estimated as gl the filtration is carried ouusing a spiralwound module with a mass transfer coefficient of times ms The protein is rejected completely by the membrane and the effects of fouling are assumed to be negligible.
a What membrane area is required for batch ultrafiltration if the process must be completed within hour?
b What membrane area is required if the filtration is carried out as a continuous operation over hour with a feed flow rate of mh
