Electrolytic Defluoridation Process

Introduction

 

Electrolytic defluoridation (EDF) system uses totally new concept for treatment of safe potable water supply in fluoride affected areas, particularly in the villages which have no electric supply and do not have alternate safe water source for potable water supply.

 

Advantages:

 

• •  Simple to fabricate, easy to operate with  minimum maintenance

  •  Suitable for treatment of raw water with fluoride concentration upto 10mg/L

  •  Produces potable water with palatable taste as against the other  available chemical treatment methods

  •  Quantity of sludge produced is much less (60-70%) than conventional treatment methods

  •  Simultaneous  reduction in hardness and bacterial contamination in treated water

  •  Treatment cost upto Rs. 20 per 1000 L

  •  Can be operated using Solar Energy

  •  Can be configured to any design capacity

  •  Operation and maintenance by unskilled operator

  •  Successfully implemented in the field and nearly 100  plants being operated in fluorosis endemic areas supplying safe drinking water to nearly 2 lakh people
