Moleaer Nanobubble Generators for Water Treatment

Moleaer is a nanobubble technology company founded in 2016 by Warren Russell and Bruce Scholten and headquartered in Hawthorne, California. It addresses the low efficiency of conventional aeration and chemical dosing in wastewater, lakes, aquaculture and irrigation, where much of the injected gas escapes before it can be used.

Its generators inject air, oxygen, ozone or other gases into water to create bubbles smaller than 200 nanometres. These bubbles stay suspended instead of rising, carry a negative surface charge and can capture fine particles and droplets, which speeds up chemical, physical and biological processes. Product lines such as Neo, Titan, Trinity, Clear, Indalo, NOVO3 and Freya are sized from small ponds to large treatment plants, and a Nanobubbles-as-a-Service rental model covers 500 to 5,000 GPM. Customers include municipal wastewater plants, lake managers, salmon and shrimp farms, greenhouses, food processors and mining and oil companies, with more than 10,000 installations in over 55 countries.

• Sub-200 nm bubbles: long-lasting, negatively charged nanobubbles that remain suspended in water.
• Multi-gas injection: works with air, oxygen, ozone and other gases depending on the application.
• Wastewater upgrades: higher treatment capacity, process stability and patented processes for anaerobic digestion and polymer activation.
• Lake restoration: chemical-free oxygenation to control algal blooms and improve water quality.
• Aquaculture and agriculture: oxygenation for fish and shrimp farms and cleaner irrigation water for higher crop yields.
• Nanobubbles-as-a-Service: rental systems from 500 to 5,000 GPM for trials and temporary needs.

Urban drainage companies in Hanoi and Ho Chi Minh City can oxygenate polluted lakes and canals without chemicals. Intensive shrimp farms in the Mekong Delta can cut oxygen and energy costs. Industrial and municipal wastewater plants can add capacity by boosting aeration with nanobubbles instead of building new basins.

Gas transfer efficiency above 85%, which the company says exceeds other aeration technologies. In wastewater, nanobubbles can add up to 20% treatment capacity while cutting energy and chemical demand by up to 40%. In aquaculture, oxygen costs fall by up to 60%. A rental model lets operators trial or deploy the technology without capital expenditure.

Urban lakes and canals in Southeast Asia suffer from eutrophication and algal blooms, wastewater plants face rising electricity costs, and intensive shrimp and fish farming in Vietnam depends on reliable dissolved oxygen. Chemical-free oxygenation and aeration technologies that cut energy use are gaining attention as discharge standards and climate targets tighten.

Founded in 2016 by Warren Russell and Bruce Scholten, headquartered in Hawthorne, California, with manufacturing in the USA and Spain and regional sites in Chile and Norway. Reports more than 10,000 installations in 55+ countries and over 550 waterbodies treated. In 2026 it received patents for nanobubble polymer activation and anaerobic treatment, signed agreements with Solenis and Xylem and was selected for the 100+ Accelerator Cohort 7.
