Plot a figure of permeate flowrate (L/h) over ultrafiltration time and describe the results.

Plot concentrations of protein in the retentate/concentrate over filtration time in a figure and describe it.

Calculate the rejection of protein at the end of ultrafiltration.

A milk mixture was prepared by dissolving of 400g of skimmed milk powder into a 10L milk solution.

The milk solution was then added to the filtration tank. The flow rate was observed over the time it took to has 2L of the solution left in the concentrate. Sample of permeate were collected until 8L total of permeate was obtained.

Water was added to the feed tank containing protein concentrate. The volume of water added to the feed tank was calculated. The addition of water results in the lactose concentration being 1/20^th of original concertation.

per 100G: Protein: 36.1g Carbohydrate: 52.9g (all carbohydrates are lactose)
