303 The Future of Wastewater
Welcome to Scaling UP! H2O, the podcast where we're passionate about water treatment, and we're committed to sharing that passion with you. Without water, we do not have a job. Without water, our planet cannot sustain life. That's why we're excited to introduce our guest today, Dr. Rakesh Govind.
Dr. Rakesh is a professor at the Chemical & Materials Engineering Department at the University of Cincinnati, and the president of NextGen Septic, a company that provides technical expertise on biological treatment processes for soil, air, groundwater, and wastewater clean-up applications.
Dr. Rakesh knows that if we don't change our water consumption and wastewater processing, some countries will run out of fresh water in the next 12 years. In this episode, he challenges the way we process wastewater and gives the biggest call to action we've EVER had on this podcast.
Dr. Rakesh answers many questions related to wastewater processing, including why we're doing it wrong and what we should be doing instead, why septic tanks aren't a good alternative to centralized treatments, and what the ideal decentralized system looks like. He also explains where aeration fits in, how we can retrofit systems to make them more efficient, and whether the size of the bubble matters when picking the right bubble for your wastewater system.
Furthermore, Dr. Rakesh shares insights into the ideal wastewater system design based on science, the ROI for industries switching from centralized to decentralized wastewater systems, and the language we should use when trying to persuade and inspire others to move away from centralized wastewater treatment.
Bottom line:
We must make swift and effective changes to the way we treat wastewater. If we don't change how we do wastewater today, we won't have any water to waste in the future. So, join us for this thought-provoking episode with Dr. Rakesh Govind, and let's explore the challenges and solutions in wastewater processing.

Quotes
"We are depriving the land of the groundwater that is being used to make wastewater." - Dr. Rakesh Govind
"The future of wastewater is decentralized treatment." - Dr. Rakesh Govind
"We have to remember that fresh water on this planet is running out. It's not going to happen in 100 years, it's going to happen in the next 10 years. By treating the water locally, industries can reuse the water, and that reduces their net consumption of water." - Dr. Rakesh Govind
"Water doesn't have to go in the sewer line, save money on utilities, reuse the water." - Dr. Rakesh Govind
"Microbubbles benefits: 1. They don't stay in the water long enough to become nitrogen bubbles 2. They coalesce, they do combine and do not repel each other which allows the nitrogen to escape 3. High efficiency of oxygen transfer." - Dr. Rakesh Govind
