A A Micro-Nano Bubble Oxygenation System generates ultra-fine oxygen bubbles with diameters ranging from 0.1 to 10 micrometers, compared to about 300 micrometers for ordinary bubbles. These micro and nano-sized bubbles remain suspended in water much longer, greatly enhancing oxygen dissolution efficiency and improving overall water quality. It is widely used in aquaculture to maintain high dissolved oxygen levels and support healthy fish growth.
