Clay pot filters for rural to purify water by NJIT students

Now when the entire world in getting into the check for the reason of development, the invention and innovation is making it possible. Talking about India’s scenario rural development has always been in prime focus. The development has been confined to agriculture, education, health, sanitation and infrastructural. Making it possible government as well as non government bodies work and bring innovation bring a new facet.

Under the same impression nearly 40 students – from biologists to engineers – are working on various aspects of the project, from the design of the clay pot filters individual families would use to purify their water each day, to the development of prototype tests that will simulate local conditions, to research into government policies that encourage the use of fertilizers that contain toxic levels of cadmium and arsenic. Their goal is to produce a prototype by the end of August.

"We’re developing a filter that will absorb both heavy metals and disease-causing pathogens," said Janitha Hewa Batagoda, a doctoral student and Sri Lankan native who is leading the team of undergraduates, primarily from NJIT’s chapter of Engineers Without Borders (EWB). "The idea is to make it easy and inexpensive to manufacture, using locally available materials, and also ensure it is simple to use. Each system would cost the equivalent of about $5 and enable families to filter 10 gallons of water a day."

The filter, which will sit inside a five-pound bucket, will be made of locally available clay mixed with hematite, a mineral containing iron oxide that binds with heavy metals. Colloidal silver, a suspension containing silver particles that captures biological pathogens such as e-coli and cholera, will be added to the filter.

The NJIT team won $15,000 to develop the idea through the EPA’s P3 – People, Prosperity and the Planet–Program, an annual competition intended to inspire college students to "design solutions for a sustainable future." In April, the team will display its project at the USA Science and Engineering Festival in Washington, D.C., where it will compete against other Phase 1 winners for the P3 Award and a grant of $75,000 to develop it as a real world application.
