Alfa Laval - LabStak M37/38

LabStak M37/38

The Alfa Laval LabStak® M37/38 is a flexible plate-and-frame test unit for ultrafiltration and microfiltration membrane processes. The unit utilizes support plates and flat sheet membranes of the same size as our full-scale membrane filtration modules. This makes the Alfa Laval LabStak® M37/38 a popular choice 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

Handy and flexible

The Alfa Laval LabStak® M37/38 is designed to provide quick and precise evaluations in laboratories and other test facilities, while keeping equipment and set-up cost to a minimum.

This flexible unit, which is designed for plate-and-frame operation, can be fitted with the full range of flat sheet membranes available from Alfa Laval for ultrafiltration and microfiltration.

Option

For the LabStak® M37/38 Alfa Laval offers alternative plate set configurations which can be selected according to use.

  • M37 plate set
    For highly viscous liquids
  • M38H plate set
    High channel, for medium viscous liquids
  • M38L plate set
    Low channel, for low viscous liquids

运行原理

阿法拉伐的板框式模块设计有横跨膜表面的开放通道。进料流/滞留物流过这些开放通道。

膜本身由带有许多槽的中空板支撑,这些槽可收集渗透液,并通过渗透液收集管从模块中排出。

v板框式模块在锁环或锁条的帮助下使用膜本身将进料/滞留物密封,防止其混入渗透通道。这也避免了板组(plate stack)本身的任何泄漏风险。
