- Nanobubble Technology
Leverage the unique properties of nanobubbles to deliver a proven, multi-pronged approach to improve wastewater treatment. From enhanced aeration efficiency and physical separation to chemical-free oxidation, these nanoscopic bubbles can improve the performance of existing aeration systes, eliminate sustained periods of low dissolved oxygen (DO), and penetrate flocs to sustain a more aerobic biomass that increases treatment capacity and improves biological oxygen demand (BOD), chemical oxygen demand (COD), and ammonia removal rates.
Nanobubbles effectively eliminate some of the most challenging wastewater treatment issues via nanobubble oxidation, hyper-efficient gas transfer, surfactant removal, and the deep delivery of oxygen to the biological floc or film. It is this combination that enables Moleaer nanobubble generators to increase dissolved oxygen levels, eliminating the anaerobic conditions that cause process upsets, degrade process performance, and generate odor and corrosion compounds like hydrogen sulfide (H2S).
In addition to improving biological and chemical oxidation processes, nanobubbles also enhance physical separation. Their neutral buoyancy, hydrophobic nature, and strong negative surface charge attracts them to water contaminants like fats, oils, grease, surfactants, colloids, and solids. As more and more nanobubbles surround the contaminant, the entrained contaminant separates from solution enabling it to be easily removed by flotation or filtration.
From New Zealand to California, from creamery DAFs to municipal oxidation ditches, Moleaer nanobubble generators are a trusted solution for overcoming some of the biggest challenges in wastewater treatment. One meat processing plant struggled with the limitations of its DAF system, seeing reduced recovery of fat: nanobubbles generated a 71% oil and grease reduction. A California craft brewery struggled with its membrane bioreactor, combatting foaming with chemicals, until Moleaer’s systems eliminated those challenges and delivered significant improvements to dissolved oxygen, treatment capacity, and removal rates. These case studies, combined with a wealth of third-party validation from universities like the University of California Los Angeles and Arizona State University, demonstrate why nanobubbles are a leading wastewater treatment technology.
