Membrane SystemR-12 Universal Membrane System

General Description: A membrane system containing one or two commercial size spiral-wound membranes. The system can be configured for RO, NF, UF or MF depending on the type of membranes and pumps employed. Membranes are in parallel when two elements are used.
Specifications: The system, as used for either RO, NF, UF or MF contains one commercial size spiral-wound membrane. Also included in the systems is a centrifugal stuffing pump, a positive displacement pump, appropriate temperature and pressure gauges, retentate and permeate flow meters and a retentate flow control valve. The membranes are placed in parallel when two elements are used. The system components are similar to those used for RO/NF with the exception of the positive displacement pump that is not required for UF/MF. Membranes routinely available include: Thin film composite RO membrane with an operational pH range of 3 - 10 and a maximum operating temperature of 120o F. The RO membrane has a typical NaCl rejection of 99.5%. Polyethersulfone UF membrane with a 10,000 MWCO, a maximum operating temperatures of 120F and pH range of 2 - 12. Each UF membrane has approximately 60 ft2 of membrane area. This type of membrane is designed to concentrate sweet/acid whey, WPC (35 - 90% protein) or skim milk to 32% total solids and whole milk to 45% total solids. System is also capable of ceramic membrane processes.
Spay Drier Niro Filterlab Spray Dryer
