Reverse osmosis pushes raw water through a semi-permeable membrane under pressure and splits it in two: permeate and concentrate. It is used in every industrial process that needs water of low conductivity.

We engineer the system around your raw water analysis, manufacture it, commission it and inspect it periodically. Our active projects run units in the 9–60 m³/h range.

How it works

Stages

  1. 01

    Raw water

    Well, mains or returned process water is taken into the system.

  2. 02

    Pretreatment

    Suspended solids and chlorine are removed; this is the stage that determines membrane life.

  3. 03

    High-pressure pump

    Provides the pressure the membrane needs. The largest energy item in the system.

  4. 04

    Membrane vessels

    Permeate goes to the process; concentrate is routed to discharge or to recovery.

Where it is used

Typical applications

  • Process water

    Low-conductivity water for production lines.

  • Boiler feedwater

    Feedwater that reduces the risk of scaling and corrosion.

  • Cooling water make-up

    Make-up water that raises the cooling tower’s cycles of concentration.

  • Water recovery

    Reuse of treated water within the plant.

Pretreatment determines membrane life

The most common mistake in reverse osmosis projects is underestimating the pretreatment. When suspended solids, hardness and chlorine reach the membrane directly, capacity falls quickly and membrane life is cut short.

That is why we never engineer an RO unit on its own; we design it as a line, together with filtration and, where needed, softening.

Frequently asked questions

When should the membrane be replaced?

When the recovery rate and the permeate quality begin to fall. Periodic inspection data indicates the replacement window in advance.

What does the recovery rate depend on?

On the raw water analysis, the membrane array and the pretreatment. Our efficiency calculation weighs all three together.

Will you work on our existing RO system?

Yes. We work brand-independently; membrane replacement and recommissioning are carried out on your existing system.
