Problem and fix

The problem this solves.

  1. 01
    The problem

    A family drinks borewell water with arsenic or fluoride, and power cuts are common.

    How it is fixed

    Water drips through a cartridge filled with a fine alumina powder. The powder holds on to arsenic and fluoride and lets clean water pass. Good minerals stay in the water and no water is thrown away.

How it works

Step by step.

  1. 1

    Fill

    Pour borewell water into the top chamber.

  2. 2

    Filter

    Water drips through a cartridge of very fine alumina powder that holds on to arsenic and fluoride.

  3. 3

    Drink

    Clean water collects in the lower chamber, with its good minerals still in it.

  4. 4

    Replace

    When the cartridge is used up, swap it for a new one.

Questions

Frequently asked questions.

Is this technology proven?

Yes. It is at ready level 6 to 9 of 9, which means: already in use. Gives 5 to 6 litres of safe water an hour. You only replace the cartridge.

What does it cost to run?

About a cartridge at INR 200 to 250. 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.
