🔧 How to install
- Fix the housing securely on the RO skid or frame
- Insert the 4040 membrane element carefully
- Fit the head assembly with proper sealing
- Tighten the locking ring securely
- Connect feed, permeate, and reject lines
- Start the system gradually and check for leaks
❓ How it works
The membrane housing functions as a pressure vessel:
- Feed water enters under pressure
- The RO membrane separates clean water (permeate)
- Dissolved salts and impurities are rejected
- Purified water flows out while waste is discharged
This ensures efficient filtration while maintaining system safety and performance.
