Study of Low-Cost Household Water Filter using Activated Rice Husk as Adsorbent

Abstract: This project demonstrates the study of water purification. Water samples are collected from four different location namely Padumpukhuri (Hojai district of Assam), Komorakata (Hojai district), Dekargaon (Sonitpur district of Assam), and GIMT, Tezpur campus(Sonitpur district). These water samples are tested for different physical and chemical parameter in our college Environmental Engineering laboratory and Tezpur (PHE) Division. Moreover our main aim is to design a low cost filter with Rice Husk Activated Carbon as the adsorbing material for purifying water. The main focus of our project is to deal with the quality of water and recover as much as clean and fresh water. Filtered water after passing layer of different proportion of activated carbon are tested for different physical and chemical parameter and compare with that of raw water. Comparison result shows that our low cost designed filter perform well to remove certain amount of chemical-physical parameter and gives good quality water.
