Students were given the task of exploring and design of the low cost water treatment technology .Students selected the locally available adsorbents as filter media and tried to explore the possibilities of low cost water treatment for rural areas with less investment without the use of power requirement.

Title of the work: Comparative Analysis of Locally Available Adsorbents for Purification of Water

It is well known fact that clean water is absolutely essential for healthy living. Adequate Supply of fresh and clean drinking water is essential for all human beings on the earth, yet it has been observed that millions of people worldwide are still drinking water that is contaminated by bacteria, toxic chemicals and other pollutants. Hence there is a need for purification of water. In the present study a low cost water filter is designed for 7 litre capacity. The filter media consists of layers pebbles, sand, corncob, and adsorbents (sugarcane bagasse, rice husk, fly ash, activated carbon, and blended activated carbon & fly ash) 4cm each. The main focus in this project is the removal of fluoride from water by using adsorption technique. The water is also tested for various parameters like acidity, alkalinity, turbidity, total dissolved solids, Hardness and pH. From this study it can be concluded that Sugarcane Bagasse is an effective adsorbent. The removal efficiencies of Sugarcane Bagasse for Acidity, Alkalinity, Turbidity, and Fluoride are 40%, 2.5%, 94.84%, and 31.42% respectively. Rice Husk has removed hardness upto 18.18%.

In this project work students learnt the idea of utilizing locally available adsorbents for purification of water in rural areas and small communities without the use of power requirements to get the purified water. Students also published this work in the International Journal (IJSART) ISSN [ONLINE]: 2395-1052, IJSART - Volume 3 Issue 6–JUNE 2017.
