After ozone dissolves in water, ozone has strong oxidation ability to quickly kill the bacteria, fungi, escherichia coli, viruses and other microbes in the water, and completely oxidize the organic matter. Ozone can oxidize the metal ions in the water, decompose small organisms that scatter light in the water, improve water quality and clarity. Ozone has the ability of rapid decomposition without any pollution and residue, convenient use, safety and environmental protection.
