ECO solar aerator is composed of photovoltaic panel components, battery packs, surface aerators, floating bodies, brackets and other main components. The photovoltaic drives the surface aerator impeller to operate. The rotating impeller stirs the water body to form splashes and water films, and expand the water. The contact surface with the air allows oxygen, surface aerobic substances and algae to quickly merge into the bottom of the water, so that the surface and lower water quality can be exchanged quickly, and the bottom exhaust gas is eliminated, and the ecological balance of the water body has been maintained. Scope of application: Reservoirs, rivers, lakes, rivers and other relatively deep waters, where the bottom and surface water interact, achieve quick results in the treatment of algae.
