In Switzerland, a team of Indian Institute of Science engineers developed an innovative wastewater filtration system that was recently awarded the first prize at the Google Pitch Fest. The device was developed specifically for remote, disaster-affected areas, and it does so without using water, membranes, or chemicals. It even generates its own ozone, which can combat microbes and other bacteria.
Another innovation is a better way to store and distribute wastewater. The company calls it a “retentate tank,” which includes a retentate tank. The system also includes a permeate tank. The retentate tank 200 is equipped with control floats that can activate electrical transmissions as water levels in the retentate tank reach a certain level.
