Multipurpose membrane filtration system

12 December 2022

Alfa Laval has launched the MultiSystem, a new cross-flow skid-mounted membrane filtration system that can be seamlessly connected to both up and downstream operations, to increase flexibility across a range of process applications. 

This includes the purification of proteins, sugar and starch, concentration of peptides and amino acid streams and recovery of water from condensates.

The MultiSystem has a test processing capacity from 100l/hr to 6m³/hr, and testing volume ranging from 500l/hr up to several m³. It can test all filtration processes, including microfiltration, ultrafiltration, nanofiltration and reverse osmosis in batch, semi-batch and continuous modes. Diafiltration mode is also available as standard.

The module is also compatible with Alfa Laval’s range of 8.0in spiral membranes, which can be d easily interchanged, and it features a PLC-based control system that enables automatic control of production sequences. This includes flow, VCF (volumetric concentration factor), temperature, tank level, pressure and diafiltration volume or ratio control.

The plant is capable of performing all of the key functions demanded of a filtration system and can transition between these, thanks its interchangeable membranes. Adopting a more flexible, standardised approach allows food manufacturers to diversify their offerings and increase efficiency without the need to invest in multiple pieces of technology.
