Ready: level 7 of 9Tested in the fieldTrial

Bacteria that clean up perchlorate.
Clean up perchlorate in wells and soil.

Water or soil near firework or rocket fuel units has perchlorate in it. Selected bacteria, working without air, turn perchlorate into harmless salt and oxygen.

Problem and fix

The problem this solves.

  1. 01
    The problem

    Water or soil near firework or rocket fuel units has perchlorate in it.

    How it is fixed

    Selected bacteria, working without air, turn perchlorate into harmless salt and oxygen.

How it works

Step by step.

  1. 1

    Seal

    Contaminated water or soil goes into a closed unit.

  2. 2

    Treat

    Selected bacteria, without air, break down the perchlorate.

  3. 3

    Release

    Only harmless salt and oxygen remain.

Key features

Why it works well.

Tested at trial size.

  • Purely biologicalNo chemicals needed.
  • Zero dischargeNothing harmful leaves the unit.
  • MobileCan move from well to well.

Questions

Frequently asked questions.

Is this technology proven?

Yes. It is at ready level 7 of 9, which means: tested in the field. Tested at trial size.

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.

Here is what works instead.
