Desalination Technology of Water by using Rice Husk Ash

Abstract

Rice husk ash produced by burning raw rice husk at 500 °C was used atvolume of 100, 150, 300 and 450 cm3 and treated with saline water with electricalconductivity 23 dS m-1 with two volumes 200 and 300 cm3 . Saline water was passedthrough rice husk ash for 30 minutes. After that some of chemical properties of salinewater were determined such as electrical conductivity (EC) , sodium adsorption ratio(SAR) and soluble ions concentration ( Ca+2 , Mg+2 , Na+ , K+ , Cl- , SO4-2 and HCO3- ).Rice husk ash was showing high ability in reducing all of studying properties withpercentage 90.04 % , 82.90% , 83.00% 98.99% , 96.94 % , 86.11% , 96.94% , 91.30%and 88.61 % respectively. The volumes of rice husk ash 300 and 450 cm3 were showedhigh significant effect compared with other treatments in reducing all values of studiedproperties.
