The Scientist’s of Bengaluru made a new invention which makes drinking water from sewage a reality. As the drinking water crisis becoming more severe, the world is looking at recovering used water. The invention by a Bengaluru-based scientist has seen his campus recover 10,000 liters of water from sewage every day which can also be used for drinking too.
The Boom Tube Resonator which is invented by Dr Rajah Vijay Kumar recovers water fit for drinking and gives high-value fertilizer as a byproduct. It doesn’t use any chemicals or microorganisms.
His team has received queries from Doha and Oman to recover 3 lakh liters per day, and from Malaysia to salvage 10 lakh liters. He said that “Singapore is interested in a large-scale project. We have excess water today and he sipped the recovered water. “It meets the drinking water standard (ISI 505),” he added.
As India is facing worst drinking water crisis, recovering water from sewage may become helpful and can be considered better for the future. These days the groundwater is depleting and on the other hand, surface water undrinkable. India consumes 693 billion cubic meters of water a year and it might increase to 942 billion cubic meters by 2025 and 1,422 billion cubic meters by 2050. India discharges 38,400 million cubic meters of sewage annually, which is enough for the country if recovered.
Water turns sewage when mixed with excreta, urine, soaps or detergents. Some of these dissolve and the rest remain suspended. Very fine particles in sewage remain in motion due to electrostatic charge (often negative), which causes them to repel each other. Once their charge is neutralized, the particles collide and combine together.
The Boom Tube Resonator applies this principle. It uses high-intensity shortwave to neutralize the fine particles present in sewage.
