TestUnit M20

The Alfa Laval TestUnit M20 is a fully integrated plate-and-frame system. It can be used for research and development, educational work, process optimization and up-scaling, as well as quality assurance and small-scale production. The unit can be equipped with our entire range of membranes for reverse osmosis, nanofiltration and ultrafiltration as well as microfiltration. By adding the optional M20-2.5” housing, you can also test with spiral membranes.

Quick and reliable unit for R&D work, membrane testing, process optimization and up-scaling

Ready to run, fully integrated membrane filtration system with LabStak M20 module, pump, heat exchanger, valve, pressure gauges, hydraulic hand pump
Flexible – membrane areas from 0.036 m² to 0.72 m² and simultaneous test of different membrane types
Multiple purpose – can combine plate-and-frame and spiral wound designs in one unit
Convenient – separate permeate outlet from each individual membrane pair
Easy exchange of spiral and flat sheet membranes

The Alfa Laval TestUnit M20 can handle cross-flows of 5 to 24 l/min and is designed to operate at high temperatures and pressures. It provides quick and precise test results, while keeping equipment and set-up costs to a minimum. The compact unit comes as a fully integrated and wheeled system comprising an Alfa Laval LabStakTM M20, high-pressure pump, tank, heat exchanger, valve, pressure gauges and hydraulic hand pump for module compression. All components comply with FDA and EEC regulations, allowing use within food and pharmaceutical processing applications.

Options

Alfa Laval M20-2538 housing

A specially designed Alfa Laval M20-2538 housing can be inserted between the module flanges of the Alfa Laval LabStak™ M20 module. The special housing makes the Alfa Laval TestUnit M20 easily convertible into a spiral wound membrane test unit for sanitary full-fit 2.5" spiral membranes. A unique combination of plate-and-frame and spiral wound membrane technologies in one unit.

Alfa Laval LabStak™ M20

The Alfa Laval LabStak™ M20 mounted in the Alfa Laval TestUnit M20 is also available as a separate test unit for the same applications as the Alfa Laval TestUnit M20, and with the same distinct properties.

How it works

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.
