Planted beds for salty wastewater.
A planted bed for salty wastewater.

Wastewater near the coast or from a factory is too salty for ordinary plants. Plants that like salt grow in a special bed that also makes a small electric current, which speeds up the cleaning.

    The problem

    Wastewater near the coast or from a factory is too salty for ordinary plants.

    How it is fixed

    Plants that like salt grow in a special bed that also makes a small electric current, which speeds up the cleaning.

How it works

Step by step.

  1. 1

    Flow

    Wastewater flows into a planted bed.

  2. 2

    Boost

    The bed makes a small electric current that speeds up cleaning.

  3. 3

    Clean

    Salt-loving plants and bacteria remove pollution and germs.

Key features

Why it works well.

Cleans wastewater up to 5 grams of salt per litre, with less sludge.

  • Salty water OKWorks where ordinary plants die.
  • Removes germsHigh pathogen removal.
  • Lasts longerLess clogging than normal wetlands.
  • Meets irrigation normsWater is fit for farms.

Questions

Frequently asked questions.

Is this technology proven?

Yes. It is at ready level 8 of 9, which means: finished and proven. Cleans wastewater up to 5 grams of salt per litre, with less sludge.

Can we try it on our own water first?

Yes. We test a sample in our NABL-accredited lab and, where it helps, run a small trial on your site before you invest in a full plant.

Do you supply and install it?

Yes. We design, supply, install and start up the system, train your staff, and our lab checks the treated water.
