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.

It is that time of the year and swimming pools are filled with people who wish to escape the heat. Before you step out this summer, ensure you have some skin protection, say experts.

Omkar Kulkarni, Head of R&D department, Netsurf Network and Austin, Head – Research and Development, Cholayil Private Limited, lists some tips.

* An earthy touch: A dip in the pool can beat the summer heat but it can leave a severe tan on the skin for months. Try a mixture of Multani Mitti (mineral-rich clay) along with few drops of lemon and rose water.

If you cannot organise a fresh extract every day, pick body cleansing products that have "neem" or "tea tree oil" as their main ingredient.

After your time in the sun, mix the ingredients and apply on exposed areas. The paste calms the skin with a cooling effect. Also apply coconut or olive oil liberally over body parts that are exposed to chlorinated water.

* Spice up your life: Water in swimming pools contains disinfectants like iodide and chlorine, which cause skin problems like acne flare-ups, rashes and red patches. Cinnamon has great anti-microbial properties. Add a few drops of honey and Aloe Vera gel to cinnamon powder to fight bacteria-causing acne. The mixture also keeps the skin moist.

* For a golden glow: Turmeric is known for its anti-inflammatory properties and cleanses pores from within. Grind neem leaves with water and mix it with one tablespoon of turmeric powder. Apply the paste on the face with few drops of rose water to clear up skin after acne break-outs and also to reduce scars naturally.

* The secret mantra: To avoid the contagious skin diseases and allergies caused by swimming in public pools, Ayurveda recommends adding neem leaf extract to bathing water. If you cannot organise a fresh extract every day, pick body cleansing products that have “neem” or “tea tree oil” as their main ingredient. (IANS)
