NOVELTY - Microbial generator(s)/bio-generator(s)/bioreactors for bioaugmenting wastewater streams, wastewater bodies, ground-waters, and any other aqueous discharges, comprises two chambers. The first chamber has inlet(s) for water, source of nutrients/food, source of microbes and source of air or oxygen, overflow, vent, and outlet. The microbes are introduced in an active state.    USE - The generators are useful for bioaugmenting wastewater streams, wastewater bodies, ground-waters, and any other aqueous discharges.    ADVANTAGE - The microbial generator optimizes and improves the efficiency of bioaugmentation, i.e. the increased concentration, and rate of bacteria added to the wastewater, of wastewater streams, wastewater bodies, ground-waters, and any other aqueous discharges.    DETAILED DESCRIPTION - Microbial generator(s)/bio-generator(s)/bioreactors for bioaugmenting wastewater streams, wastewater bodies, ground-waters, and any other aqueous discharges, comprises two chambers (1, 15). The first chamber(s) has inlet(s) for water or liquid (2) utilizing a method to control the fill level of the chamber(s), source of nutrients/food, source of microbes (7) and source of air or oxygen (10), overflow, vent, and outlet. The second chamber(s) has inlet(s) to receive liquid from the first chamber(s), source of air or oxygen, overflow, vent and outlet attached to a metering device to control the bioaugmentation of wastewater streams, wastewater bodies, ground-waters and any other aqueous discharges. The microbes are introduced in an active state.    An INDEPENDENT CLAIM is also included for a method for performing bioaugmentation of a site (20), comprising filling a container with an aqueous liquid, preferably water; adding microbes; adding nutrients/food; aerating the liquid to achieve desired level of dissolved oxygen; and metering the liquid into a bioaugmentation site.    DESCRIPTION OF DRAWING(S) - The figure is a view of the microbial generator utilizing two chambers.
