Incubator for biological cleaning of fluids

An apparatus for cleaning polluted fluids by providing an environment for microorganisms to biologically degrade pollutants, said apparatus comprising:

• a housing having one or more sidewalls defining an elongated chamber and two ends, said one or more sidewalls being substantially fluid impermeable and having at least one area which is light transmissive, said area being light transmissive defining a section of the housing for orientation towards sunlight, with the ends of said elongated chamber laterally disposed with respect to each other, said light transmissive area for permitting sunlight to enter said chamber to provide energy for photosynthesis and to provide soar heating of the chamber;
• bouyancy means secured to the housing providing bouyancy to float the housing above or below fluids in which said housing is placed, to maintain the area which is light transmissive oriented towards the sunlight when the apparatus is placed in polluted fluids and to maintain said ends of said chamber laterally disposed with respect to each other;
• a matrix held within said chamber of said housing to provide a support for microorganisms which are capable of acting on the polluted fluids;
• and
• circulation means in fluid communication with said chamber for propelling growth media and polluted fluids laterally through the said matrix from end to end to provide microorganisms carried on the matrix with growth conditions for acting on polluted fluids,
• said housing for placement in a body of polluted fluids with said area which is light transmissive oriented towards sunlight to allow microorganisms held on said matrix to perform a photosynthesis and to provide heat to said chamber, and said circulation means providing a substantially horizontal flow of growth media and polluted fluid to maximize oxygen contact with the microorganisms carried on said matrix and to allow the microorganisms to act on said polluted fluid.
