Sanitary Reverse Osmosis Membrane
Element Introduction
- Streamlined internal flow channel accelerates waste discharge during CIP, shortens cleaning duration and reduces chemical consumption with zero material residue.
- Particular focus goes toward preserving product integrity, keeping processed fluid separated from potential contaminants during running and servicing cycles.
- It is well‑adapted for incorporation into sanitary process setups requiring robust operational stability, low fouling‑contamination risk and consistent long‑duration performance.
Principal Product Advantages
- Built upon a hygiene‑centric engineering principle, the membrane element aims to bring down contamination hazards along the complete fluid‑touching flow channel.
- Its inner wetted surfaces are optimized to mitigate material retention and prevent zones where product residuals could gather during running or system shutdown.
- Fully adaptable to mainstream industrial cleaning routines, the element can thoroughly strip organic, inorganic and bio‑based residues without taking the system apart.
- Engineered for tough process conditions, this sanitary membrane delivers steady hygienic performance throughout extended continuous running cycles.

FAQ
Q1: What is the maximum operating pressure?
A: Max operating pressure ≤50 bar. Allowable pressure for cleaning cycles:75‑100psi(5.2‑6.9bar). Overpressure operation is forbidden.
Q2: What is the pH working range?
A: Nominal operating pH:2‑10. Sanitation‑cycle pH:1‑13. High‑pH cleaning mode cannot be used for long‑term production.
Q3: Can you provide non‑standard sizes?
A: Yes. Available sizes include 1812,4040,8038,8040. Please contact us to evaluate your custom requirement.
Q4: What about residual chlorine tolerance?
A: Tolerable residual chlorine ≤0.1 ppm. Feed water dechlorination is required to prevent membrane oxidation damage.
