Dairy and Whey Applications

Membrane filtration is one of the most important separation technologies used in modern dairy processing. It enables efficient concentration, fractionation, purification, and demineralization of milk and whey streams while preserving valuable proteins and lactose. The process separates a liquid stream into two fractions through a semipermeable membrane:
- Retentate (concentrate) — retained proteins, fats, or larger molecules
- Permeate — water, lactose, salts, minerals, and smaller dissolved compounds passing through the membrane By selecting different membrane pore sizes and operating conditions, dairy producers can concentrate or selectively remove specific components from milk and whey streams.
Stable concentration readings start with the right installation
Drifting total solids or Brix readings in dairy membrane filtration? Your refractometer installation could be the reason.
Low flow velocity around the measurement window can allow deposits to build up, causing readings to drift. If your refractometer is installed in a pipe bend or T-piece, the local flow conditions may be affecting measurement reliability.
Better flow across the measurement window. Better process control.
The KxS hygienic straight flow cell (SFC) positions the DCM-20 refractometer’s measurement window directly in the main process flow. This helps keep the measurement window clean, reduce fouling and maintain stable, real-time concentration readings.
- Designed for demanding dairy applications, including whey ultrafiltration (UF) and reverse osmosis (RO), its 3-A and EHEDG-certified hygienic design supports:
- Reliable concentration monitoring in retentate and permeate streams.
- Consistent process control with less measurement drift caused by prism fouling.
Confident endpoint control to help maintain product consistency.
Since its introduction in 2020, whey producers have adopted the KxS straight flow cell to improve measurement stability in membrane filtration.
