MIT's brainchild Gradiant is making waves by tackling the colossal water footprint left by industrial practices. The company, started by MIT alumni, Anurag Bajpayee and Prakash Govindan, is an end-to-end water technology provider pushing the envelope in water recycling, treatment, and purification for behemoths such as Coca Cola, Tesla, and the Taiwan Semiconductor Manufacturing Company. According to an article by MIT News, Gradiant's technology is helping reuse 2 billion gallons of water daily, reducing fresh water consumption significantly and cushioning the blow to our ever-strained water resources.
Industrial processes devour vast quantities of water, for instance, the production of a single iPhone may guzzle over 3,000 gallons. Gradiant's founders are all too familiar with water scarcity. Govindan grew up in a drought-stricken part of India, his personal experience birthing a respect for this precious resource. After meeting at MIT and developing their water treatment technologies, the duo took their innovations from academia to the real world, with Gradiant's proprietary carrier gas extraction technology at the forefront of their suite of solutions. As Bajpayee told MIT News, "Our customers aren’t water companies; they are industrial clients like semiconductor manufacturers, drug companies, and food and beverage companies. They aren’t about to start operating a water treatment plant. They look at us as their water partner who can take care of the whole water problem."
The scalability of Gradiant's innovations is evident in its global reach, with more than 2,500 customized water treatment systems established worldwide. The company's technological arsenal includes advanced techniques like reverse osmosis, selective contaminant extraction, and free radical oxidation, all patented. Moreover, Gradiant has embraced digitalization, wielding AI to optimize the management of water treatment facilities. Gradiant's pursuit to refine and diversify its technology stack reflects its commitment to sustainability and industrial efficiency. It's not just about water conservation but also about resource recovery, as Gradiant has developed a method to extract valuable minerals such as lithium and nickel from wastewater, pointed out by Bajpayee as a potential game-changer for meeting domestic lithium demands in the U.S.
Addressing the persistent challenge of toxic 'forever chemicals' like PFAS, Gradiant has illustrated success in a pilot project with a U.S. semiconductor manufacturer to eradicate these substances from water. This breakthrough could soon safeguard municipal water supplies, hinting at broader community-level benefits. At the core of Gradiant's drive is the philosophy that industry need not drain our natural reserves dry. Bajpayee emphasized to MIT News, "By treating and recycling water, by reducing water consumption and making industry highly water efficient, we have this unique opportunity to turn the clock back and give nature water back."
