This company’s polypropylene (PP) spiral membranes (photo) are said to be more compact than alternatives, and thus provide a larger filtration area for a better performance and the possibility to produce a wider product range. These membranes deliver sustainable benefits, such as reduced water and chemical consumption, as well as longer service life, which means less maintenance and downtime. The PP spiral membranes are even more hygienic than conventional membranes, as they withstand high numbers of cleaning-in-place (CIP) cycles, hot cleaning temperatures and high pH levels. — Alfa Laval AB, Lund, Sweden
