PRESERVOL™ P – 45 LB. Pail – Membrane Preservative and Winterization chemical




PreservolTM P is a powdered membrane preservative for MF/UF and NF/RO systems. PreservolTM P provides a safe and effective solution for the storage of membrane elements for extended periods without loss of performance. Store membranes in-situ to avoid shipping, offsite preservation and storage costs, while also reducing the potential for biological growth in the ancillary tanks and piping of the system. Best suited to membrane systems intending to be offline for more than a few days. PWT highly recommends a full system cleaning (such as OptiCleanTM B and OptiCleanTM A) prior to preservation with PreservolTM P.
