A smart water-recycling system for kitchen sink designed by science and engineering students of GITAM (Deemed to be University) to reduce water crisis in Indian cities has won the grand finale of SMART. India Hackathon at the Nodal Center BS Abdur Rahman Crescent Institute of Science and Technology, Tamil Nadu, Hardware Edition. The team working on Project Hydrogravity was declared the winner in their problem description category among five other teams competing from different parts of India.
The students designed an eco-friendly and smart grey-water filtration system called HydroGravity, which is capable of catalyzing biogas. It recycles the dark gray water that comes out of the kitchen sink after dishwashing.
Smart India Hackathon (SIH) 2022 is an initiative of the Central Government to provide a platform to the students to solve their day to day problems, thereby inculcating a culture of product innovation and problem-solving mindset. The event was organized by the Ministry of Education, Ministry of education Innovation Council, and All India Council for Technical Education, among other partners.
The students of GITAM (Deemed to be University) were working on a problem statement in the field of Water Harvesting given by the Department of Science and Technology. He took home the prize money of Rs 1 lakh for his innovation.
The team’s students including Anik Panja, Prithvi Tripathi, Jesswin GN and Shivani Narsina are pursuing B.Tech courses at GITAM’s Visakhapatnam campus.
Team coach Vikas Kumar Srivastava said, “Facing Chennai’s water crisis, the students decided to throw the kitchen sink at the problem. As part of the core technical team at GITAM’s IEEE student branch in 2019, he was required to innovate a group project related to water conservation. Incidentally, with the acute shortage of water for daily use, the water crisis in Chennai was at its peak. The event became the key catalytic event for the team to embark on the project of recycling kitchen sink water after dishwashing. It took the students 2.5 years to take the concept to the prototype stage through multiple designs and iterations. ,
Team coach Bolem Raja Kumar said, “The students have designed a self-maintaining, smart and retrofitable rainwater and greywater filtration system. It has multiple stages equipped with filters and sedimentation tanks with grease traps. Sand and charcoal filter water. The built-in sensors provide real-time data on water quality and parameters such as pH, turbidity, TDS and water content. Filtered water can be used for irrigation, cleaning and flushing toilets Individually the science behind every step exists in the real world in pieces and pieces. Students integrate all of these systems and engineer them to fit in a confined space.”
Student Anik Panja, one of the team leaders, says, “An average household is estimated to generate around 356 liters of gray water per day. This is a huge amount if multiplied by the thousands of restaurants and millions of homes in a city. This water currently goes into the sewer. Its recycling can go a long way in meeting the chronic water shortage. We’ve built a plug-and-play graywater recycling system that can be retrofitted to existing kitchen pipes. We have integrated multiple sensors into the system, allowing it to adjust the self-maintenance cycle and generate a live report for the user to monitor water usage and output quality.
Another student, Prithvi Tripathi, said: “We have been allocated funds and space by GITAM to build and test our prototypes, giving us the ability to rapidly fine-tune the product. This will be our pilot project.”
