​​​​​​​​​​​​​​​​​​​​​​​​Membrane filtration solutions for dairy, plant-based and alternative ingredient products​

Membrane filtration supports efficient production of milk- and whey-based foods and beverages as well as high-value nutrients for infants, sports people, and seniors. It is also used to concentrate plant-based proteins, to purify alternative proteins. 

 

Membrane filtration also facilitates process water recovery and reuse, meeting high-quality standards. Traditional food processing often results in wastewater being dismissed down the drain. But with membrane filtration, it can be reused for equipment cleaning or even in food processes where it has direct contact with the product itself. Treated water can surpass even drinking water standards in some regions.

Tetra Pak® UF system P

Tetra Pak® UF system P is a pre-engineered ultrafiltration system for concentrating milk or whey proteins to make value-added dairy products. Like all ultrafiltration solutions, it uses membranes to remove water, minerals, and lactose from dairy streams during the production process. Tetra Pak UF system P comes in two versions: one adapted for the North American market and the other for the rest of the world.

Membrane filtration processes

Within the dairy industry, four different membrane filtration processes are used: microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO). The figure illustrates which milk and whey components can be concentrated by means of each process, depending on the density of the membrane.

Filtration unit

Microfiltration

Microfiltration

NF separates a range of minerals from a liquid, allowing only the fluid and certain monovalent ions to pass through the membrane.

• Bacterial removal
• Casein standardization
• Brine treatment
• Cheese milk preparation
• Fat removal
• Extended shelf life
• MCC production

Filtration unit

Nanofiltration

Nanofiltration

NF separates a range of minerals from a liquid, allowing only the fluid and certain monovalent ions to pass through the membrane.

• Demineralized milk and whey
• Salt reduction
• High solids concentration
• Infant formula

Filtration unit

Ultrafiltration

Ultrafiltration

The ultrafiltration (UF) membrane separates the feed (e.g. skim milk) into two streams, allowing water, dissolved salts, lactose, and acids to pass through it in either direction, while retaining (and thereby concentrating) proteins and fat.

• Protein standardization
• Brine treatment
• Milk: MPC/MPI
• Whey: WPC/WPI
• Lactoferrin
• De-calcification

Filtration unit

Reverse Osmosis

Reverse Osmosis

RO is the tightest possible membrane process in liquid separation. It concentrates the total solids, and only water can pass through the membrane; all dissolved and suspended material is rejected.

• Solids concentration
• Milk concentration
• Whey concentration
• UF permeate concentration
• Buttermilk concentration

Filtration unit

Microfiltration Ultrafiltration

Microfiltration uses the most open type of membrane, which is used to separate bacteria, spores, and fat globules from the stream, and for fractionation of skim milk.

​ • New Food fermentation
• Plant protein concentration, fractionation, and standardization
• Bacterial removal
• Juice clarification
• New protein sources
• Plant based drinks
• Plant based yoghurt
• Plant based protein ingredients
• Tofu
• Coconut, orange, and other juices

Filtration unit

Reverse Osmosis Nanofiltration

RO is the tightest possible membrane process in liquid separation. It concentrates the total solids, and only water can pass through the membrane; all dissolved and suspended material is rejected.

• Solids concentration and standardization
• Sugar standardization
• Tea and coffee concentration
• Plant based powder

Reverse Osmosis Nanofiltration

Reverse Osmosis is the tightest possible membrane process in liquid separation. It concentrates the total solids, and only water can pass through the membrane; all dissolved and suspended material is rejected.

• Product recovery
• Process water recovery
• CIP chemical reclaim
• Reduction of freshwater consumption
