Nanobubbles generate high concentrations of reactive oxidants that support oxidative degradation processes. This helps reduce BOD, COD, ammonia, nitrate, and fecal coliform levels—significantly improving key water quality indicators, such as dissolved oxygen. At the same time, organic silt is oxidized and broken down, helping eliminate odors, enhance water clarity and color, and restore overall water quality. Nanobubbles also supply oxygen to various aquatic organisms, supporting respiration and promoting the restoration and rebuilding of healthy aquatic ecosystems. Ultimately, nanobubble technology enhances the water body’s natural self-purification ability and long-term sustainability by effectively reducing total pollutants.
