Water purification in remote locations

Invention Number: 
A solar powered, scalable solution to address water decontamination and purification primarily for developing countries.

Many countries have inadequate or non-existent water decontamination facilities, particularly in remote locations that lack electricity. 

The Technology 

The present research program addresses these challenges through the design, construction, and field trials of a modular, scalable, simple, and robust water purification system. It is designed to decontaminate all forms of wastewater, including groundwater, sewerage, and industrial wastewater.

Key Benefits

  • Integration of a photovoltaic power system with a water decontamination system

  • Self-contained, portable, targeted, and economical water decontamination system
  • Decontamination of: 
    - Particulates (Screening)
    - Suspended solids and Iron (Sand-bed filter)
    - Fluorine, heavy metal and salinity (Zeolite ion exchange)
    - Arsenic (Precipitation)
    - Organics, Bacteria and Parasites (Photocatalytic reactor)
    - Nitrogen, Phosphorus, Sulphur (Bioreactor)
    - Residues (Membrane filter)


  • Wastewater purification
  • Domestic and Municpal groundwater purification
  • Sewerage processing
  • Industrial water processing
  • Photovoltaics manufacturing
  • Ceramic manufacturing
  • Membrane manufacturing
