UF & RO Performance Assessment

Understand membrane performance. Plan the next step.

Independent assessment of ultrafiltration and reverse osmosis systems to investigate deterioration, assess cleaning results and prioritise improvements.

Discuss your membrane system

Put performance changes in context.

We review operating trends alongside feed conditions, pretreatment and cleaning history to assess likely causes and identify further checks.

A focused assessment for each membrane process

Ultrafiltration (UF)

  • Temperature-corrected permeability and TMP
  • Flux, filtration cycles and net recovery
  • Backwash, CEB and CIP performance
  • Filtrate quality and integrity-test records

Reverse osmosis (RO)

  • Normalised permeate flow and salt passage
  • Differential pressure and train comparisons
  • Recovery, flux and specific energy use
  • Cleaning response and feedwater conditions

Assessment methods and reference conditions depend on the membrane system and available data.

What our assessment covers

  1. 01

    Performance trends and baselines

    Check data quality and establish suitable comparisons.

  2. 02

    Fouling, scaling and integrity concerns

    Assess likely causes and identify evidence needed to confirm them.

  3. 03

    Pretreatment and feed conditions

    Review upstream performance and membrane compatibility.

  4. 04

    Cleaning effectiveness

    Compare performance before and after cleaning.

  5. 05

    Recovery and resource use

    Review water losses, energy demand and operating constraints.

  6. 06

    Further investigation

    Define targeted checks to confirm likely causes and close evidence gaps.

What you receive

An evidence-based assessment with prioritised recommendations.

  • UF and RO performance findings
  • Suitable baselines, where data supports them
  • Likely causes and remaining uncertainties
  • Cleaning and operational recommendations
  • Further testing requirements
  • Replacement considerations, where justified
