Membrane Cleaning
CIP programmes that restore membrane flux and rejection without unnecessary element replacement.
Overview
What this covers.
Diagnose foulants, apply a tailored clean chemistry, then verify recovery of ΔP and permeate quality. Used on RO, UF and other membrane systems with progressive fouling or rising OPEX.
Applications
Where this is typically used.
- RO, UF and other membrane systems
- Progressive fouling or rising operating cost
What we deliver
Scope on this offering.
- 01Foulant diagnosis
- 02Tailored CIP chemistry

Process
How the work typically runs.
01
Diagnose foulants
Read ΔP, permeate quality and operating history.
02
Clean to the foulant
Apply chemistry matched to scale, organics or biofilm.
03
Verify recovery
Confirm ΔP and permeate quality before leaving site.
Benefits
Why this specification.
- Restore flux and rejection before replacing elements
- Flux restored without unnecessary element replacement
- CIP chemistry that protects membrane polymer
Questions
Asked before we start work.
When is cleaning better than replacing membranes?
- When flux and ΔP have drifted from fouling, not from irreversible damage. We diagnose first so you are not replacing elements that a CIP can recover.
Do you supply the cleaning chemicals?
- Yes. Cleaners are matched to organic, inorganic or bio foulants, and we protect membrane polymer and elastomers during the cycle.
