Alfa Laval PP spiral membranes

Alfa Laval's range of membrane filtration equipment includes its PP spiral membranes. The compact membranes offer a large filtration area, which is said to give the user better performance and the possibility to produce a wider product range. Benefits include reduced water and chemical use as well as longer service life, meaning less maintenance and less downtime.

Membrane filtration is a clean technology. The separation process is carried out solely on the basis of molecular size, making the use of additives unnecessary. This results in an end product of high quality and makes it easier to comply with the many stringent requirements from both consumers and public authorities. The spiral membranes are said to be more hygienic than conventional membranes as they withstand high numbers of cleaning-in-place (CIP) cycles, hot cleaning temperatures and high pH levels.

Membrane filtration can be used for products with a wide range of different viscosities, including high-viscosity products that can be difficult to process. The company's membrane filtration equipment is designed on a modular basis that gives a high degree of flexibility. The design of a system can be customised to meet any process needs and is easy to expand if production requirements increase.
