DEFLUORIDATION OF GROUNDWATER BY USING MODIFIED MORINGA SEEDS POWDER Mrs. Ramya H.N.1, Mr. Kiran B2, Mr. SAJJAN K.S.3, Ms. AMBIKA N.S.4, Ms. BHOOMIKA T5 B.E., Department of Civil Engineering, Channabasaveshvara Institute of Technology, Tumkur, India ---------------------------------------------------------------------***--------------------------------------------------------------------2.1 Collection of moringa oleifera Seeds Abstract - De-fluoridation of ground water is necessary to eliminate the fluoride content in water. The maximum fluoride content was found to be 3.07mg/L, which was recorded from the tube wells of Jajurayanahalli village in Pavagada taluk, Tumkur district [May 2022]. The permissible range of Fluoride in potable water is 0.6-1.2mg/L according to Bureau of Indian Standard. Excess fluoride in potable water causes tooth and bone fluorosis also whole part of the body. Hence, it is necessary to reduce the fluoride content in ground water. There are different techniques for fluoride like precipitation method, exchange method, electro-coagulation method etc. where the adsorption technique was found to be efficient & effective for the fluoride elimination. The efficient adsorbent was found in Moringa Oleifera seeds powder which is having 90-95% percent fluoride elimination potency.
Moringa oleifera seed powders are used in this project were collected from drumstick trees from Tumkur. The seeds shells were removed manually by hands and de-husk the seeds kernels, then washed with distilled water and dried in solar until 7 days. The dried sample powdered in a grinder at home, then sieve the sample to get a particle length of 300µm.
Key Words:
Moringa Oleifera, Adsorption, Fluoride elimination potency. Fig-1: Moringa oleifera with pods
1. INTRODUCTION Fluoride content in water is required for all forms of life. Day by day quality of water is decreasing by human activities. Fluorines are generally found in rocks and minerals. Fluoride has dual significance it is advantage, when it is in permissible limit when limit exceeds it causes many problems. Excess fluoride content in water causes skeletal and dental fluorosis. Fluorine is the chemical element having the atomic number 9 and found in a periodic table it is a P block element having a melting point of 53.48K and boiling point 85.03K. The permissible limit of fluoride varies from 0.6-1mg/L according to IS 10500:2012. One of the most successible methods for decreasing fluoride content in drinking water is adsorption.

Collection of water samples
For this project water samples are collected from tube-wells of the Pavagada Taluk, Tumkur district, during May 2022. About 5 liters of water are collected and then basic tests like pH, fluoride ion concentration, turbidity, total hardness is examined by Environmental laboratory, (C.I.T. Gubbi)
