Alfa Laval’s PP spiral membranes are compact, allowing a larger filtration area for better performance and the ability to produce a wider product range. These membranes offer sustainable benefits such as reduction of water and chemical use and a longer service life, meaning less maintenance and less downtime. Membrane filtration is a clean technology. The PP spiral membranes are more hygienic than conventional membranes as they withstand high numbers of Cleaning-in-Place (CIP) cycles, hot cleaning temperatures and high pH levels.
