Specifications

Specifications

  • Filter all particles above 5 Microns

  • Production cost of <$20

  • Reduce Turbidity by 50-75 %

  • Life Cycle of 6000 Hours (2-5 years)

  • Flow rate of 1 L/min

  • Little to no upkeep, consumables needed should be locally available

  • Reduce fluoride content by 50-70%

Fluoride Removal

Particle Removal


Fluoride removal

Fluoride Removal

  • Electro dialysis

  • Adsorption – locally available sources

    • Fixed bed adsorption in a packed column

      • Bone Char – charred at 500 degrees C or optimal adsorption

      • Egg Shells


Fluoride removal concerns

Fluoride Removal Concerns

  • Assuming starting concentration of 20 mg/L, A life expectancy of 6000hrs with a flow rater of 1 L/min

  • 5.5 milligrams of fluorine adsorbed per gram of adsorbent required

    Adsorption of Fluoride from Water Solution on Bone Char

    Rosa M. Guerrero-Coronado,† and Laura Fuentes-Rubio†

  • To achieve a 50% reduction in fluoride concentration over the life of the filter 654.545 kg (1443.02 lbs) of bone char would be required
