Alfa Laval - LabUnit M37/38

LabUnit M37/38

The Alfa Laval LabUnit M37/38 is a fully integrated plate-and-frame system for ultrafiltration and microfiltration membrane processes. The module of this unit utilizes the same support plates and membranes as our full-scale membrane filtration modules. This makes the Alfa Laval LabUnit M37/38 a flexible tool for process development, up-scaling, membrane testing, quality assurance and small-scale production. Optional plate sets are available for feeds of different viscosity / solids content

Fully integrated, easy-to-use pilot equipment for membrane filtration tests

  • Fully integrated – complete with LabStakTM M37/38 module, pump, pipework, valves, heat exchanger and instrumentation
  • Flexible – different channel height options available to optimize flow and pressure
  • Easy membrane exchange, flexible membrane area (between 0.11 and 1.05 m²) and simultaneous test of up to 7 different membrane types
  • High operating temperature (up to 80°)
  • Low internal volume

The Alfa Laval LabUnit M37/38 can be fitted with our full range of flat sheet membranes for ultrafiltration and microfiltration. The flow pattern is similar to that in larger systems which makes it easier to scale up and test our filtration equipment. The unit can be connected to the by-pass stream of an industrial plant. All components comply with FDA regulations, allowing use within food and pharmaceutical processing applications.

Choice of plate sets

The Alfa Laval LabUnit M37/38 has a number of plate sets with different channel heights to optimize flow and pressure:

M37 plate set For high viscosity liquids
M38H plate set High channel, for medium viscosity liquids
M38L plate set  Low channel, for low viscosity liquids

The Alfa Laval LabStakTM M37/38 module installed in the Alfa Laval LabUnit M37/38 is also available as a separate test module for the same applications as the Alfa Laval LabUnit M37/38, and with the same distinct properties.

How it works

.
Flow diagram of typical installation
Flow diagram of typical membrane filtration installation

The feed stream/retentate flows through the open channels across the membrane surface in the plate-and-frame unit.

The membrane is supported by hollow plates with numerous slots that allow the permeate to be collected and removed from the unit via the permeate collecting tubes.

Plate-and-frame units use the membrane itself, aided by lock rings or strips, to seal off the feed/retentate and prevent any mixing with the permeate. This also prevents leaks from the plate stak itself.
