How nanobubbles solve tough problems at Water Resource Recovery Facilities

Water Resource Recovery Facility (WRRF) operators are seeing new problems that previously had no solution until now.
Over the last couple of decades, there have been two major shifts in municipal #wastewater characteristics. First, water conservation and low flow appliances necessitated by water scarcity and drought have concentrated wastewater contaminants over time. Second, the increased use of surfactant-based products like surface cleaners and liquid soaps and detergents, especially after the pandemic, paired with fats, oils, and grease (FOG), interfere with nearly all #wastewatertreatment processes because they impede solids separation, oxygen transfer, and nutrient removal, and consume disinfection chemicals. These changes in wastewater characteristics have created new operational challenges and have increased the cost-to-treat wastewater.
Moleaer’s technology uses air and water to generate in-situ chemistry in the form of nanobubbles that selectively target contaminants that cause inefficiencies and odors in wastewater treatment. Nanobubbles enable process intensification by breaking down slowly biodegradable contaminants like #surfactants and FOG to more readily biodegradable compounds, making the wastewater easier to treat.
In this webinar, Dr. Ragy Ragheb, Malvern Panalytical’s Application Scientist, talks about how #nanoparticle tracking analysis with the NanoSight product range is used to measure, view and study nanobubbles that are used by Moleaer’s R&D team. Dr. Laureanne Parizot, R&D Scientist at Moleaer, discusses and shares data on how Malvern Panalytical’s equipment was used to study nanobubble/surfactant interactions that supported Moleaer’s findings and helped with application development. Lastly, Andrea White, P.E., Moleaer’s Global Director of Water Process Engineering, covers the findings of a case study on the Goleta Sanitation District WRRF where nanobubbles were used to treat 4.2 million gallons per day of municipal wastewater.

About Moleaer
Moleaer is an American-based nanobubble technology company with a mission to unlock nanobubbles’ full potential to enhance and protect water, food, and natural resources. Moleaer has established the nanobubble industry in the U.S. by developing the first nanobubble generator that can perform cost-effectively at municipal and industrial scale. Moleaer’s patented nanobubble technology provides the highest proven oxygen transfer rate in the aeration and gas infusion industry, with an efficiency of over 85 percent per foot of water (Michael Stenstrom, UCLA, 2017). Through partnerships with universities, Moleaer has proven that nanobubbles are a chemical-free and cost-effective solution to increasing sustainable food production, restoring aquatic ecosystems, and improving natural resource recovery. Moleaer has deployed more than 2200 nanobubble generators worldwide since 2016. To learn more, visit: www.Moleaer.com
About nanobubbles
Nanobubbles are tiny bubbles, invisible to the naked eye and 2500 times smaller than a single grain of table salt. Bubbles at this scale remain suspended in water for long periods, enabling highly efficient oxygen transfer and supersaturation of dissolved gas in liquids. Nanobubbles also treat and eliminate pathogens and contaminants of emerging concern as well as scour surfaces to break apart biofilm matrices, creating a powerful, sustainable, and chemical-free disinfectant (Shiroodi, S., Schwarz, M.H., Nitin, N. et al., Food Bioprocess Technol, 2021).
