"AMRIT" Water Purifier Provides Low Cost Arsenic Free Water



Introduction

AMRIT – Arsenic and Metal Removal by Indian Technology is a customisable nanotechnology based water purifier developed at the Chemistry Department of IIT Madras.

Product or concept

Developed affordable nano-technology based water purifier to dispense safe drinking water.

Problem being solved

Provide safe and arsenic free water at affordable prices.

Process or technology involved

 

The purification process takes place in two stages:

  • First the microbial impurities are removed by killing them with very small concentrations of silver ions released from silver nanoparticles.
  • After this, the chemical impurities like arsenic, lead, iron etc. are removed with the help of different nanomaterials that remove the chemicals one by one, in a selective manner.

There are two versions of the water purifier based on volume – commercial and domestic purpose.

Sustainability benefits

  • Provides water at a cost of less than 5 paisa/litre.
  • The purifier is adaptable to local conditions and the type of contamination.
  • Reduces the arsenic content in water to less than 2 parts per billion.

User segments that will benefit

  • Municipal Corporations
  • Hospitals
  • Residential Communities
