PilotUnit Multi

The Alfa Laval PilotUnit Multi is a multipurpose system with a broad selection of options that makes it possible to test all different kinds of membrane filtration products for microfiltration, ultrafiltration, nanofiltration and reverse osmosis in batch or semi-batch mode. It is an ideal tool for easy and reliable scale-up of processes or even small-scale production.

Fully integrated, space-saving and state-of-the-art filtration system with broad selection of options

Easy to use – fully integrated system on a wheeled stainless steel structure. Data logging included and easy access via USB
Compact and robust – comprises housing for single 3.8" spiral membrane, 40 l tank, pump, heat exchanger, valves, instruments and control system
Low hold-up volume for high product concentration and minimal test media amount
Flexible – pump system can handle low to high viscosity solutions and operates with the whole range of feed spacers (30-80 mil).
Adaptable – suitable for pHt™ membranes with high temperature and pH tolerance

Alfa Laval PilotUnit Multi has a flexible membrane area (3–15 m²) and can handle volumes between 50 and 1000 l. The basic unit is available with a number of options, including online monitoring and data collection, to enhance the performance of your membrane filtration process. You can double the spiral membrane area by adding another housing, while the addition of an Alfa Laval LabStak™ M39H module enables you to simultaneously test different MF/UF flat sheet membranes (up to 2 m²). If you want to test our membrane filtration products for nanofiltration and reverse osmosis you will find an option for this as well.

動作原理

The Alfa Laval PilotUnit Multi comes as a skid-mounted unit and includes all necessary instruments, equipment and prefabricated piping ready for operation. All you need to do is to install and connect to the product feed, utilities and the power supply.

The product enters the tank via the feed valve (with level control). It is then pumped to the membrane filtration stage where the system automatically adjusts the pump speed and maintains the required cross-flow rate to reduce fouling and ensure the smooth concentration of your product.

The operator can adjust the controllers from the MemProC^®PLC-based control system which includes a data logging system for the unit transmitters. The data can be downloaded to a USB.

膜ろ過の基本的な技術は、半透膜を使用して液体を二つの異なる流れに分けることに関わっています。

この液体を膜の表面を横切ってポンプすると、膜の細孔よりも小さい成分が通過できるように、正の膜を介した圧力が生じます。これにより、透過液が形成されます。

細孔サイズよりも大きい成分は通過できず、リテンテートと呼ばれるものに残ります。膜の表面は、膜表面に平行に移動する液体の流れの力によって、閉塞がない状態に保たれます。
