Question

A protein solution has concentration of 10 kg m-3 and diffusivity 2x10-11 m2 s-1. It must be concentrated using ultrafiltration. The filtration is gel layer controlled, and gel concentration is 300 kg m-3. The filtration takes place in a thin channel with equivalent diameter 2 mm and width 4 cm, with cross flow velocity 0.5 m s-1. If a filtrate rate of 100 l/day is required, find the length of membrane module needed

Answer 1

Explanation:

concentration of ultrafiltration is gel layer controlled with gel concentration of 150 kg/m. 3 ... rate is 150 L/h, protein diffusivity is 3x10. -11 m. 2. /s. Find the permeate.
