Questions
Frequently asked questions.
Is this technology proven?
Yes. It is at ready level 9 of 9, which means: already in use. Low-cost drinking water from water that was being thrown away.
What does it cost to run?
About under 20 paise a litre. The exact figure depends on your water and the size of the plant. We confirm it after testing a sample.
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.
