TEKNO-THERM
Nanofiltration (NF)
A membrane separation method positioned between ultrafiltration and reverse osmosis. It is used to remove bacteria, viruses, organic residues and hardness. Lower cost and higher efficiency compared to the Evaporation–Electrodialysis system.
Membrane Separation Technology
“Membrane filtration systems are widely used in industry. Nanofiltration is an advanced membrane separation method positioned between ultrafiltration and reverse osmosis.”
Nanofiltration technology is used effectively to remove bacteria, viruses, organic residues and hardness-forming components. With low energy consumption, the system provides high process efficiency, offering the advantages of both increased concentration and partial demineralization.
While generating lower operating costs compared to traditional evaporation and electro-dialysis combinations, it allows concentration and demineralization processes to be carried out simultaneously.
The Advantages of Nanofiltration
Concentration + Demineralization in a Single Step
The evaporation and electro-dialysis processes, traditionally carried out as two separate processes, are optimized within a single system.
Low Water and Energy Use
Thanks to the compact system architecture, energy and water consumption are minimized, reducing operating costs.
Partial Demineralization
NaCl and KCl — monovalent salts — achieve high permeability, while organic compounds such as lactose and protein maintain low permeability.
High Fractionation Success
Thanks to smaller membrane pores compared to UF and MF systems, more precise and effective separation performance is achieved.
Easy Maintenance & Long Life
Thanks to the compact system size, simple maintenance procedures and long membrane service life, service processes are simplified.
Key Applications in the Dairy Industry
Nanofiltration technology provides high efficiency, low energy consumption and advanced product separation advantages in milk and dairy product processes.
