Development of affordable, robust disinfection system for rural India
The “Development of affordable, robust disinfection system for rural India” Department of Science and Technology Project ((DST/TM/WTI/2K14/228)) initiated by Dr. S.M. Maliyekkal, Professor – School of Mechanical and Building Sciences and Dr. P.C. Sabumon, Professor – School of Mechanical and Building Sciences aims at providing sustained access to clean drinking water at the Point of Use (POU) is the mammoth task and it has been identified as the key challenges in the Millennium development goals of United Nations. World Health Organization (WHO) reports that there are about 3.275 million deaths occurred over the world due to drinking water related infections. The present work is focused on developing a film with antibacterial property consists of biopolymer template with reinforcing agent decorated with silver nanoparticles through an eco-friendly method. The nanocomposite showed excellent antibacterial property against gram positive and negative bacteria. The significant 99.9999% disinfection of E.coli for multiple cycles and the sustained, controlled release of silver ions makes this nanocomposite material a promising candidate for the disinfection of drinking water.
