Question:
Diafiltration is used to purify 40 L of dilute protein solution produced in a pilot plant. The solution has 0.8 percent protein and 3.2 percent salts, and the protein/salt ratio should be 50:1 after diafiltration.
(a) If pure water is added intermittently, 40 L at a time, what is the total amount of water needed?
(b) How much water would be needed with continuous addition and constant retentate volume?
(c) If a subsequent UF step raises the protein concentration to 5 percent, what is the final salt concentration?
