MAX Ultrafiltration Spiral-Wound Element
MK MAX (PES 30kDa)
Synder Filtration’s Ultrafiltration Elements offer an optimal combination of both flux and rejection in a comprehensive range of MWCO’s. Contact us today to learn more about our complete line of membrane products and services.
Synder’s MK ultrafiltration membrane was developed in 1999 specifically for the concentration of milk proteins from skim milk, to boost the protein content in the total solids. Since its launch, it has been widely used throughout the world for this application, and is also used for other applications such as skim milk protein (MPC/MPI) concentration, egg white concentration, and blood protein concentration. This PES-based membrane offers good temperature and pH resistance and offers excellent membrane durability, making it a cost-effective method for protein concentration.
