Optimized spiral wound UF membranes
Alfa Laval ultrafiltration membranes are recognized for their exceptional durability and superior chemical and thermal stability. Offered as flat sheets for laboratory testing and spiral elements for large-scale operations, they enable seamless scale-up and deliver cost-effective performance with lower energy consumption compared to other membrane filtration methods, such as reverse osmosis. They are also highly efficient, eliminating the need to replace or dispose of cartridges and consumables used in traditional dead-end filtration.
With the new addition of DuroLac™ UF spiral membrane elements, we are now offering up to 15% increase in permeate output per element, significantly boosting plant performance.
Our spiral wound UF membrane materials comply with all major industry regulations, including EU Regulations 1935/2004, 10/2011, and 2023/2006, as well as FDA CFR Title 21. Related equipment, such as plate-and-frame modules and auxiliary equipment, is also compliant, ensuring safe and efficient filtration across food and pharmaceutical applications.
UF-pHt™ series
UF-pHt™ membranes tolerate high temperatures and pH values. The membranes are made of polysulphone or polyethersulphone on polypropylene support material. MWCO values range between 2,000 and 100,000 Dalton. Most of the spiral membranes are USDA approved and Halal certified.
Dairy series
Alfa Laval has two series of spiral membranes tailor-made for dairy applications: Dairy UF-PET and the Dairy UF-pHt™.
The dairy UF-PET spiral membranes, which are manufactured with polyester support material, are available with MWCO values between 5,000 and 10,000 Dalton.
The dairy UF-pHt™ spiral membranes, which are cast on polypropylene backing paper, are available with MWCO values between 5,000 and 20,000 Dalton.
Both types are USDA approved and we can offer products with Halal certificates upon request.
