Abstract
The method and apparatus of the invention are directed to the removal of pollutants from ponds, lagoons, streams, and similar waters. Floating apparatus is designed to house, nurture, and support colonies of fixed-film bacteria and/or more complex microorganisms specifically appropriate for consuming the particular contaminants present in the pond being treated. The colonies of microorganisms are first grown as bio-films in a relatively large bio-chamber that is filled with bio-suspension forms. Then, only after the colonies become large and stable, is pond water circulated through the bio-chamber, such circulation being gentle and without agitation. The apparatus also includes (a) a pond-water intake; (b) a water mixing chamber; and (c) an equipment pod which houses water and air pumps, a water heater, a weather station, water-condition monitoring devices, and a microprocessor. Also, special methodology and apparatus make it possible to establish such large and stable colonies of appropriate microorganisms in cold water.
