AL-Mem

Applications

The Alfa Laval Membrane-UF system (AL-mem UF) is normally used as a concentration and purification stage within other processes, reducing the volume of a liquid by removing water and other low-molecular substances.

The AL-mem UF system can be used for cost-effective concentration of proteins, gums and other feeds prior to further evaporation. Units of this type are widely used for installations processing blood plasma, gelatine, egg, pectin extract, carrageenan and chitosane. Also for the production of natural colours and for the recovery of protein from waste streams these units are the ideal choice.

The actual process temperature is related to the particular feed product being treated. Typical temperatures lie in the range of 5 to 90^°C (41 to 194^°F).

Design

The Alfa Laval Membrane-UF system is supplied as a frame-mounted plant with pre-assembled components and prefabricated piping. It is ready for operation as soon as it is installed and connected to external supply systems.

The system offers easy, reliable operation along with straightforward maintenance thanks to its pre-assembled and frame-mounted setup. This helps keep downtime to a minimum.

The piping, pumps, strainers, valves and fittings as well as the control panel are all manufactured by Alfa Laval. This provides significant advantages in terms of effective service and reduced spare parts inventory.

All piping and equipment in contact with the product or cleaning liquids are of sanitary-level design, as are also the spiral membranes. Steel parts are made of AISI 316L stainless steel.

The AL-mem UF system is controlled and monitored via a PLC operator panel which includes a motor control centre equipped with frequency drivers on pumps to keep down energy consumption.

Product concentration and purification are conducted in continuous mode which is automatically controlled. Cleaning is based on operator controlled and monitored CIP procedures.
