Municipal RO drinking-water treatment train
Reverse osmosis membrane changeout

- Facility type
- Municipal RO drinking-water treatment train
- Project scale
- 820 membrane elements handled (400 removed, 420 installed)
- Membrane elements
- FilmTec 440i elements (removed)
- FilmTec Eco Platinum 440i elements (installed)
The challenge
A municipal reverse osmosis treatment train required a complete membrane changeout to restore performance, executed within a tight six-day shutdown window under strict contamination control.
Outcome
The RO train was returned to service on schedule with all 420 replacement elements installed and verified vessel-by-vessel, supported by documented QA/QC at each hold point.
Scope of work
- Shutdown, isolation, depressurization, and zero-pressure verification
- Controlled removal and staging of 400 spent FilmTec 440i elements
- Pressure-vessel inspection of closures, adapters, seals, and O-rings
- Installation of 420 FilmTec Eco Platinum 440i elements to approved loading
- Vessel reassembly to manufacturer torque and closure requirements
- Flushing, leak-check, and startup support with QA/QC hold points
