DSS Membranes and Membrane Filtration Systems for the Dairy Industry

DSS Silkeborg AS is a world leading specialist in membrane filtration technology for the dairy processing industry. Our core technologies include reverse osmosis, nanofiltration, ultrafiltration and microfiltration.

MEMBRANE FILTRATION SYSTEMS

At DSS, we have all the necessary experience to design and manufacture the best possible membrane filtration plant for the specific dairy process. In addition to our expertise in the actual membrane filtration process, we have extensive knowledge of other areas of dairy production. This makes DSS the ideal supplier for integrating a membrane filtration plant in both existing and new processing applications.

DAIRY APPLICATIONS FOR MEMBRANE FILTRATION SYSTEMS

DSS supplies membranes and membrane filtration systems for applications including:

• Whey processing: RO concentration, NF concentration / demineralisation, UF protein concentration (WPC / WPI)
• Milk treatment: RO concentration, UF protein concentration (MPC, MPI) UF protein standardisation, MF protein fractionation / casein standardisation
• High-yield UF cheeses: feta and domiati, cream cheese and quark varieties
• Process water recovery: from RO and NF permeate, evaporator condensate, product flush water
• Cheese brine clarification: using DSS’ proprietary BrineClear™ system

MEMBRANES FOR DAIRY PROCESSING APPLICATIONS

DSS membranes are specifically developed for dairy applications, and we continuously improve and extend out range to provide an even more comprehensive service.

SPIRAL-WOUND UF ELEMENTS

Our spiral-wound UF membrane elements, designed for dairy processes, are based on recognised materials that secure optimum separation, superior flux, long element lifetime, high mechanical strength and good cleaning properties.

DSS UFPE series are cost-efficient, high-flux UF elements, designed primarily for whey and skim milk processing.

DSS UFPP series are resistant to high temperatures and extreme pH values. This makes them highly suitable for concentrating products such as milk, cultured milk and cream.

SPIRAL-WOUND RO AND NF ELEMENTS

RO and NF elements supplied by DSS are high quality, sanitary elements for dairy processing. Our range consists of standard RO and NF elements, heat sanitisable RO elements and extreme pH / temperature-resistant RO elements.

SPIRAL-WOUND MF ELEMENTS

Compared to traditional MF systems, spiral-wound MF elements require a significantly smaller investment in plant machinery and are extremely cost-efficient to operate.

DSS MF membrane elements are widely recognised as the most effective method for cheese brine clarification. We have recently introduced new MF membrane elements for cost-efficient fractionation of whey protein and casein in skimmed milk.

PLATE-AND-FRAME FILTRATION SYSTEMS

DSS plate-and-frame systems are the perfect solution for high-viscosity concentrates and fermented products such as cream cheese, quark and other fresh cheeses.

MEMBRANE FILTRATION TECHNOLOGY EXPERTISE

DSS brings a knowledge-based approach to the supply of membrane filtration technology for dairy processing. Our most important resource is our staff, who have years of combined experience in dairy membrane filtration and process technology.

This unrivalled experience gives us the expertise that leading dairy processors demand, and more than 300 dairy companies worldwide benefit from DSS technology every day.

DSS is an independent, flexible organisation in which resources are used effectively for customer benefit. That is why we are extremely competitive.

OUTSTANDING SUPPLY TO THE DAIRY INDUSTRY

Virtually all of the biggest dairy companies in Europe – and many other major companies in the rest of the world – have chosen DSS as their supplier for membrane filtration systems. In the past nine years, we have installed and commissioned more than 400 membrane filtration systems, and we have supplied membranes for an even larger number of plants.

Today, our growth continues, consolidating our position as the world’s largest specialist supplier of dairy filtration membranes and systems.
