FAQ

Q1: How often does the HYDRAcap®MAX60 membrane need to be cleaned?

A1: Cleaning frequency depends on feedwater quality and system design. Typically, a CIP (Clean-In-Place) is recommended when transmembrane pressure increases by 30% or more. Preventive cleaning every 1–2 weeks is common in high-purity applications.

Q2: What pretreatment is necessary before the HYDRAcap®MAX60 membrane?

A2: Pre-filtration using cartridge filters (e.g., 5-micron melt-blown filters) is recommended to protect the membrane from abrasion and fouling. Proper control of SDI (Silt Density Index) and turbidity ensures optimal membrane performance and extended service life.
