Effective Fluoride and Arsenic Removal Using Electrochlorination Technology
Arsenic or Fluoride in drinking water cause various health problems.There are many ways to remove the same from drinking water.
Pristine Water and NEERI (National Environmental Research Institute, Government of India) have developed a technique which can easily remove contaminants in drinking water using the process of Electrocoagulation
Pristine Water's E-Coagulation Electrolytic Arsenic or Fluoride removal systems are very easy to operate and maintain. It follows a simple electrolytic process to filter out the impurities from water
The AC is converted to DC by the rectifier provided in our panel. In remote areas where power supply is not available or not continuous, we offer a Solar Energy based system as well.
System designA Batch Arsenic / Fluoride Removal System treats the inlet water / wastewater in one or several 'batch' tanks of various sizes.
Continuous Arsenic / Fluoride Removal System are usually used to treat larger flow rates of water / wastewater
We also offer the solar powered variant for the arsenic and fluoride removal system with Photovoltaic Panels and Battery.
This has been especially designed for use in remote areas where electricity is either unavailable or is not continuously available.
In the process of Electrocoagulation, oxidation reaction occurs which causes dissolution of the anode. Aqueous Al3+ species are formed. The electrode reactions are outlined below:
Anodes: Al(s) → Al3+ +3e-
Cathodes: 2H2O +2e- → H2(g) +2OH-
The H2 bubbles float and hence drive the flotation process. The Al3+ ions further react to form a solid Al(OH)3 precipitate:
Al3+ + 3H2O <-> Al(OH)3(s) + 3H+
The basic principle of the process is adsorption of Arsenic and fluoride at precipitated Al.
Al(OH)3 as depicted in reaction:
Al(OH)3 + xF- → Al(OH)3- xFx + xOH-
