    When installed on aerobic lagoons, Moleaer’s nanobubble systems pump wastewater into the container housing the nanobubble generator using an industrial pump. The wastewater goes through the nanobubble generators and back into the wastewater, injecting nanobubbles and transferring high concentrations of oxygen gas into the lagoon.
