Domestic filter for defluoridation of water

Type:  Equipment
IPR Status:  Patent
Application/uses: 

Filtration of fluoride contaminated water for drinking purpose

Salient Technical Competing Features: 
  • Domestic type adsorption based multi-stage water filtration unit
  • Comprised of AA+FIA+SIAC adsorbents
  • Effective reduction of F- concentration from ~ 5 ppm to below permissible limit (~1.5 ppm)
  • Simultaneously useful for bacterial remediation since standard SIAC is used
  • No electricity
  • Flow rate: ~ 5-6 L / hour
  • Adsorbent life (average): ~2000 L
  • Storage capacity: ~15 L
Content Details: 

IPR Details :

Patent: “A spinel alkaline earth metal ferrite impregnated activated alumina adsorbent and a process thereof” Filed on April, 2016

Implementation Status and Scale of Implementation :
The developed defluoridation unit will be deployed among the fluoride affected areas of Birbhum, West Bengal for the necessary feedback from the users 

Level/Scale of Development:  May be considered TRL-5 since the prototype (integrated system) is verified in the laboratory
