Toronto, Nov 15, 2016: Indian-origin researchers at York University in Toronto have developed a solution for water treatment that uses only naturally available antimicrobial substances and sugar.

The paper strip solution called “DipTreat” is laced with sugar to kill E. coli bacteria in contaminated water.

“We were able to efficiently remove almost 90 percent of bacteria by dipping the special paper strip, DipTreat, in contaminated water samples,” said one of the researchers Sushanta Mitra.

The discovery will be key to developing a new generation of inexpensive and portable water treatment devices, with human health benefits around the world – from the far north of Canada to the remote villages of India, Mitra said.

“Now with DipTreat, we have learned it will take less than two hours to fish, trap and kill E. coli in water,” Mitra, Professor at York University’s Lassonde School of Engineering.

While using porous paper strips to trap the bacterial cells, for killing, the researchers used an antimicrobial agent extracted from the seeds of moringa — commonly known as drumstick or horseradish tree.

As a result, the DipTreat solution for water treatment uses only naturally available antimicrobial substances and sugar, with minimal environmental and health impact.

Currently, popular water treatment systems use silver nanoparticles and clays, whose long term impact on human health is yet to be fully understood, according Mitra.

So far, DipTreat is effective for small quantities of water. For example, someone who is hiking can collect a glass of water and then dip the paper strips to purify it before drinking.

The researchers believe that the invention could lead to a much greater impact.

Google Takes Initiative To Clean And Make Our Planet Healthy

The tool suggests simple changes-like installing a low-flow showerhead and fixing common household leaks-that can help you be more water smart.

Google has teamed up with the California Academy of Sciences to launch an interactive new tool that will help reduce environmental footprint by informing the amount of water your shower uses or the impact of throwing away food or turning down the water heater by a few degrees.

The tool called Your Plan, Your Planet is an interactive way to understand your environmental impact and learn simple, science-based ways to improve it.

“We all want a healthy planet. The small choices we make each day can help us get there. Learn simple tips from Google and the California Academy of Sciences to leave the earth in better shape,” Google said in a blog post late on Friday.

“Our greatest impact on the planet comes from just three things: our food, water, and energy usage. And if we each made a few small changes, we could all make a big difference,” wrote Jill Puente, Planet Earth Advocate, in the blog post.

Food production accounts for more than two-thirds of the world’s water use, and over a quarter of carbon dioxide emissions.

Your Plan, Your Planet, shows the water and carbon impact of what people eat and gives them smart ways to store it so that less food ends up in the trash.

The tool also suggests simple changes-like installing a low-flow showerhead and fixing common household leaks-that can help you be more water smart.

Much of the energy we use comes from burning natural resources, which in turn releases CO2 into the air. But easy tweaks, like washing laundry on a cold and adjusting the thermostat just a few degrees, can reduce the impact in a big way, Puente noted. (IANS)
