15. Membrane filtration equipment

Brand and model:Alfa Laval – LabStak M20.

Capacity:5–50 L.

Description:The system is equipped with a high-pressure pump, a 7.5 L tank, heat exchanger, valves, gauges, and a manual hydraulic pump. Its design allows the use of flat sheet or spiral membranes for reverse osmosis, nanofiltration, ultrafiltration, and microfiltration processes.

The sample to be filtered is placed in the tank and driven by a centrifugal pump. The sample temperature is regulated by a shell-and-tube heat exchanger using water as the cooling fluid. The filtered fluid or permeate can be returned to the feed tank to operate the system in recirculation mode or sent to a new container to operate in concentration mode.
