  • Process for microaquaculture and pollution control
    Patent number: 4935148
    Abstract: Method for producing and removing dissolved and particulate matter from natural bodies of water and wastewater in situ for the production of organic biomass such as feedstocks, for the removal of pollutants, nutrients, toxins and other substances, and for other purposes. A gas is introduced through a diffuser into a body of water to form bubbles. The bubbles rise within a lifting tube, gathering dissolved and particulate matter on their surfaces. The bubbles produce a foam at the surface of the body of water, the foam being collected in a reservoir, concentrated and drawn off.
