The self-contained and semi-automatic Alfa Laval MultiSystem in a sanitary design is a flexible and multipurpose membrane filtration system for food processing applications. It works with MF, UF, NF and RO cross-flow filtration processes and operates in both batch, semi-batch and continuous modes. The Alfa Laval MultiSystem fits the entire range of 8.0" spiral wound membranes available from Alfa Laval. This includes also the high temperature and pH tolerant Alfa Laval pHt™ membranes.

How it works


The sanitary Alfa Laval MultiSystem is a semi-automatic and fully integrated skid mounted membrane filtration system which can be easily connected to the up-and downstream unit operations in the process, minimizing installation time and cost.

The basic Alfa Laval MultiSystem comes with all necessary sanitary components such as pumps, housings, feed/CIP tank, valves, heat exchangers, transmitters, fittings and control panel.

The PLC-based control system secures automatic control of production sequences including flow, VCF (Volumetric Concentration Factor), temperature, tank level, pressure and diafiltration volume or ratio control.

Internal data logging is easily extractable via USB.



The basic Alfa Laval MultiSystem is further available with the optional equipment:

  • One extra housing to increase the spiral membrane area by 50%
  • Online monitoring and data collection
  • Remote monitoring and control (VNC) and collection via direct connection on Profinet or Modem connections (secured VPN)

Unmatched membrane technology and membrane filtration equipment

Optimum membrane filtration solutions normally derive from small-scale trials. That’s where you establish process feasibility, determine design data for up-scaling, optimize existing production lines or even carry out small-scale processing.

When it comes to membrane filtration processes, Alfa Laval is perfectly placed to help with those experiments. Our experience with membrane solutions dates back almost as far as the membrane technology itself and stretches across all the common types of filtration. Today we develop, manufacture, install and service membrane solutions and systems ourselves. So, with Alfa Laval, you tap into unmatched know-how and experience with membrane technology that comes with understanding every step of the process, and our people’s unique ability to address your needs at whatever stage of membrane filtration equipment development.

All materials used for the production of Alfa Laval membranes, in both spiral-wound and flat-sheet designs and configurations, comply with EU Regulation (EC) 1935/2004, EU Regulation 10/2011, EU Regulation (EC) 2023/2006 and FDA regulations (CFR) Title 21. The membranes are thus suitable for use within food and pharmaceutical processing applications.

These compliance also extend to the equipment and fittings related to membrane operations, including items such as plate-and-frame units, element housings and pumps.
