Services & Maintenance
AMC, membrane cleaning, dosing setup, retrofits and emergency support — lifecycle care that keeps plants running.

Overview
What this service covers.
Maintenance is planned work: inspections, CIP, dosing calibration and upgrades carried out so the plant is less likely to stop without warning. Crown structures this around the equipment in operation — RO, UF, softening and utility trains.
Problems solved
Typical site issues we take on.
- Maintenance done only when something fails.
- Rising ΔP and falling permeate quality with no CIP programme.
- Dosing that wastes chemical or leaves membranes unprotected.
Scope of service
What is included.
- 01Annual maintenance contracts with scheduled inspections
- 02Membrane CIP matched to foulant type
- 03Chemical dosing setup and calibration
- 04Retrofits, upgrades and emergency attendance
Process
How the work typically runs.
01
Agree the interval
Define what will be checked, cleaned and recorded on each visit.
02
Service the plant
Carry out inspections, CIP or upgrades with as little disruption as the site allows.
03
Record the next step

Benefits
Why sites use this service.
- Predictable cost and fewer unplanned stoppages.
- Flux and rejection restored without unnecessary element replacement.
- The same team on AMC, chemistry and emergency response.
