SAFE DRINKING WATER / 06
One plant for fluoride, arsenic and iron.
One plant for water with more than one problem.
The water has two or three problems at once, for example fluoride and iron. The water is cleaned in stages.

Problem and fix
The problem this solves.
- 01The problem
The water has two or three problems at once, for example fluoride and iron.
How it is fixedThe water is cleaned in stages. First the iron is turned into rust and settles out. Then filter cartridges remove fluoride and arsenic. There is no RO membrane, so almost no water is wasted.
How it works
Step by step.
- 1
Oxidise
Iron in the water is turned into rust.
- 2
Settle
The rust settles out in the first tank.
- 3
Filter
Replaceable cartridges remove fluoride and arsenic.
- 4
Store
Safe water goes to a storage tank of up to 1,200 litres.
Key features
Why it works well.
Arsenic below 10 µg/L, iron below 0.3 mg/L and fluoride below 1.5 mg/L. Sizes from 450 to 10,000 litres an hour.
- No membraneAlmost no water is wasted, unlike RO.
- Small footprintNeeds little space to install.
- Replaceable cartridgesCartridges last about 6 to 7 months in normal use.
- Gravity basedLow running and upkeep costs.

Questions
Frequently asked questions.
Is this technology proven?
Yes. It is at ready level 6 of 9, which means: working model tested in real conditions. Arsenic below 10 µg/L, iron below 0.3 mg/L and fluoride below 1.5 mg/L. Sizes from 450 to 10,000 litres an hour.
What does it cost to run?
About 1 to 4 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.
