Project : Pilot scale in-situ application for arsenic and fluoride removal from the groundwater: A safe drinking water production perspective 

Project Leader: Prof. Manish Kumar, IIT Gandhinagar

The research study aims at developing a potential system by coupling nano technology with bio technology for removal of geogenic contaminants from water at in-situ conditions. In this case, the projects aims at development of Janus particle, capable of removing both Arsenic and Fluoride from water, and then embed these particles with chosen biopolymer for eventual fabrication of nano-polymer system for safe water production. The research systematically investigates how geogenic contaminants are transported and retained in porous media (Biopolymer).

Objectives and Deliverables:

  • Generation of Janus particles capable of removal of multi-contaminants of geogenic origin, in this case the Arsenic and Fluoride ions.
  • Choose a biopolymer in which the Janus particle can be embedded
  • Pilot scale development of in-situ decentralized safe water production system integrated in groundwater-well system.
  • Pilot scale application and demonstration of the new system.
  • Cost-benefit and life cycle assessment pertaining to the new developed system.
