How it works: In the electrostatic field, due to the polarization of water molecules caused by biological potential changes, changes in cell surface charge, promote bacterial aggregation, impede the normal metabolism of the bacterial cells, leading to the death of bacteria and algae. Also, because the dissolved oxygen in the water mediated by the electrostatic field, such as the release of activated oxygen radicals on the cell membrane, the cell damaging effects of a variety of enzymes, leading to the death of bacteria and algae.
