We have various methods for Dairy Filtration and the goal of all methods is to separate various by-products from one another.
There are four different membrane filtration processes to filter milk and they are described below:
Nano filtration
Through this process, we can remove a range of different minerals from liquid, letting only the liquid and specific monovalent ions to pass through the membrane.
Ultra filtration
This process is used to separate skim milk into two different streams, which allows water, salts, lactose, and acids to pass through the membrane while keeping concentrates like proteins and fat.
Micro filtration
This process uses the most open kind of membrane. It’s used to remove spores, bacteria, and fat globules from the liquid and also for fractionation of skim milk.
Reverse Osmosis
We used the tightest membrane possible in liquid separation. That means that only water can pass through the membrane while all other material (dissolved and suspended) is removed.
