WebWhey comprises 80 – 90 % of the total volume of milk entering the process and contains about 50 % of the nutrients in the original milk: soluble protein, lactose, vitamins and minerals. Whey as a by-product from the manufacture of hard, semi-hard or soft cheese and rennet casein is known as sweet whey and has a pH of 5.9 – 6.6. WebDiafiltration at higher protein concentrations reduces flux, increasing the need for membrane area but decreasing the required buffer volume. Therefore, there is an optimum protein concentration at which to perform diafiltration where the tradeoff between flux and volume is balanced and the minimum membrane area or process time is achieved.
