💦A duo from DTU aims to make India’s water supply safer. They are behind an invention that purifies water directly in rooftop collection tanks using just a small amount of electricity. In many countries, such as Denmark, we are used to having clean water flow steadily when we turn on our taps. In stark contrast, a huge proportion of the population in the world’s most populous country, India, gets their water from rooftop collection tanks. These tanks are highly vulnerable to contamination from disease-causing microorganisms, and the water therefore requires purification before it is safe to use. With their product NJORD aqua, a DTU start-up, has set out to ensure people have access to potable water from such tanks. The idea is to use electricity to convert naturally occurring salt in the tank water into chlorine. This makes the water suitable for drinking, cooking and washing. “When you see these water installations, you sometimes can’t believe your own eyes, because they’re at optimal temperatures for microbial growth, and some of them are partially uncovered or have holes in them. One of our test users even told us that he had problems with monkeys opening the tank and swimming around in it,” says co-founder Andreas Sixten Hallstein Rygaard. On a reconnaissance trip to India with his business partner Viktor Ryle Tamstorf, he witnessed firsthand the challenges with the water supply there.
