BIT STUDENTS DESIGN WATER PURIFIER DEVICE

In developing countries like India, the major problem faced is the impurities in the drinking water. To overcome this, many solutions are suggested. But they are all unsustainable and not cost-efficient. The water causes in developing countries include scarcity of potable -water, floods, the siltation of river systems, contamination of rivers and large dams and polluting water by various other means. Nearly 1.1 billion people have inadequate access to fresh water. A study says that 1.8 million children die each year from diarrhoea and water-borne diseases.

A 5-member team comprising of four students from the Department of Electronics and Communication Engineering and one student from the Department of Information Technology of our Bannari Amman Institute of Technology has developed water purifying device, NeerAathar, which is capable to detect the presence of contaminants and measures the concentration of the same.The main aim of NeerAathar is to use in public tanks and reservoirs.

The student’s team named as,¨HACK O´ HOLICS¨ has constructed such an inestimable device. This team has taken the step to solve water crises and related problems by purifying it efficiently. The technology of  ‘Image processing’ plays a major role in the analysis.

When a specific reagent is added to the sample collected from the tank, then the colour of the sample changes in accordance with the concentration of the pollutants present. This principle is scientifically referred to as ‘Colorimetry’ in which the concentration of the reagent present is calculated by measuring the intensity of the colour of the solution. This device also analyses the mass of heavy metals present and some other adulterations that are harmful to human health and removes the contaminants.

This device also analyses the mass of heavy metals present and some other adulterations that are harmful to human health and removes the contaminants. Normally, the contaminants are chemically compensated or removed. Here, our students use Bio-products for the removal of the contaminants. These products are completely natural, extracted from the seeds and roots of the certain plants.

SOCH HACKATHON

Our institution takes many steps to galvanize students to involve in the research field. Also, our institution has supported the students initiative by sponsoring the total estimated cost for the project. Our students of HACK O´ HOLICS have participated in Sunrise Open Contest Hackathon conducted by India and Israel organized by Innovation Valley, Government of Andhra Pradesh on February 2&3 at Visakhapatnam. The students have won a cash prize of 1.5 lakh in this international contest. Additionally, as a wonderful opportunity, they are going to get the funding from Israel to develop their project into a commercial product in collaboration with Innovation Valley, Andhra Pradesh.
