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
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.
Unique perforated plate design arranged in a stak allowing lab testing of different membranes at the same time and under identical process conditions.
How it works
Flow diagram of typical 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.
