SALTY WATER, RO AND MEMBRANES / 03
UF plant that wastes almost no water.
Safe water from germ-laden sources, with almost no waste.
The water is not salty but has germs or mud. An RO plant would only waste water here. UF (ultrafiltration) membranes have holes so small that germs and mud cannot pass, but salts and minerals can.

What it achieves
The key numbers.
of water used.
of bacteria removed.
of viruses removed.
Problem and fix
The problem this solves.
- 01The problem
The water is not salty but has germs or mud. An RO plant would only waste water here.
How it is fixedUF (ultrafiltration) membranes have holes so small that germs and mud cannot pass, but salts and minerals can. The membranes are made in India.
How it works
Step by step.
- 1
Pre-filter
Large particles are removed.
- 2
UF membrane
Water passes through hollow fibres with holes too small for germs.
- 3
Supply
Safe water goes to taps, minerals intact.
Key features
Why it works well.
Uses over 95% of the water. Removes 99.9999% of bacteria and 99.99% of viruses.
- Almost no wasteOver 95% of the water is used.
- Germ barrierStops bacteria, viruses and mud.
- Low energyNeeds far less pressure than RO.
- Made in IndiaMembranes are manufactured locally.

Questions
Frequently asked questions.
Is this technology proven?
Yes. It is at ready level 7 to 9 of 9, which means: already in use. Uses over 95% of the water. Removes 99.9999% of bacteria and 99.99% of viruses.
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.
