Wastewater, the world’s dirty (not so little) secret, consumes nearly 3 percent of the global electricity demand. It’s a staggering statistic, and yet much of what actually happens with wastewater remains a mystery. Treatment plants typically purify water by infusing it with oxygen, creating an environment where bacteria can break down waste. But without proper sensors or data, the method is incredibly energy-intensive. Plus with an influx of unregulated chemicals, our waste streams are becoming more toxic and harder to clean. In this episode of Solve for X, environmental microbiologist Patrick Kiely shares his unusual solution that harnesses the power of bacteria to help solve our wastewater problem. Unpleasant yet fascinating, Kiely’s work offers a glimpse into what it takes to clean our water and why treating wastewater is the next big climate problem.

Featured in this episode:

• Patrick Kiely is the CEO and founder of SENTRY, a real-time monitoring biosensor system for wastewater treatment. With extensive training in environmental microbiology, his unique knowledge of bacterial growth across diverse environments forms the basis for advanced decision-making in water and wastewater technologies.
