Questions

Frequently asked questions.

Is this technology proven?

Yes. It is at ready level 7 to 8 of 9, which means: finished and proven. Nothing is wasted in the process.

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.

THE NEXT STEP

Fix it on
your own site.

Send us a water sample or a test report. We will check it, confirm this method fits and tell you what it costs to run.
