Membrane replacement is the most decisive maintenance job on an RO system. Whatever brand the system is, if the replacement and the commissioning that follows are not done correctly, the expected capacity is never reached.

We work brand-independently: we supply the membranes for your existing system, replace them and recommission the unit. On our active project in Alaşehir we are carrying out the replacement of 48 × 8" membranes and the commissioning of the system.

Membrane Replacement
How it works

Stages

  1. 01

    Diagnosis

    The measurement points are read and the stage where the loss occurs is identified.

  2. 02

    Supply

    A suitable membrane is selected; lead times and alternatives are shared.

  3. 03

    Replacement

    The vessels are opened, the membranes replaced and the seals checked.

  4. 04

    Commissioning

    The system is started up and pressure and permeate quality are measured.

Where it is used

Typical applications

  • Capacity loss

    When the permeate flow rate drops below what is expected.

  • Quality loss

    When permeate conductivity starts to rise.

  • Rising pressure

    When the pressure needed for the same flow keeps climbing.

  • Planned maintenance

    When periodic inspection data shows the replacement window.

Find the cause before replacing

Replacing a membrane sometimes amounts to nothing more than postponing the problem. If the cause of the capacity loss lies in the pretreatment, the new membrane will foul just as fast. That is why we assess the pretreatment and softening stages together before any replacement.

Brands

Brand-independent selection

We select the most suitable product according to the raw water analysis; a brand change is possible on existing systems.

  • Veolia
  • Pentair

Frequently asked questions

Can we change the membrane brand?

Yes; once suitability for the existing vessels and the raw water has been assessed, a different brand of membrane can be used.

How long does the replacement take?

It depends on the number of membranes in the system and the access conditions on site; we share the plan before starting work.
