Description: "Access to clean water is a major international issue that must not be ignored. Our research is finding a new method for the disinfection of drinking water. Even so, chlorination is the most common treatment for the disinfection of drinking water, but has a lot of disadvantages. Disinfectant by-products (DBP’s) produced by the chlorine disinfection process can cause health problems such as cancer to humans that drink water or inhale vapor. Also some bacteria are able to adapt to this chemical treatment. This is why we are proposing a physical treatment using Ultra Dispersed Diamond (UDD) for the disinfection of drinking water. The UDD is a nanodiamond powder, which has bactericidal properties and is biocompatible. After applying the UDD material to the contaminated water we have promising results. There was a reduction of fecal E. coli colonies as time passed and the density of the material increasesThis process will be healthier, cheaper, and more environmentally friendly since it is reusable."
