Abstract: An aerobic bacterial generator and related methods are disclosed. The generator has a bottom base portion, an aeration ring, and a body column extending from the bottom base portion. The body column has tapered side walls that terminate in a discharge orifice. The tapered body column is wider at its bottom than at its discharge orifice. The aerobic generator generates an improved plume by the upward flow of waste liquid through the generator, thereby creating an improved turnover of oxygen-enriched liquid in a laminar fashion.

Abstract: The invention described herein provides a novel modification of an aerobic bacterial generator, typically used for sewage wastewater treatment. By providing a pre-filter one creates the equivalent of a “sub-gravel filter” known to the aquarium trade. In such fashion the device is portable and can be placed at the bottom of any pond, lake or other body of water to act as an aeration and biological filtration device. Further the unit incorporates a means of inoculation and maintenance of cultures of beneficial bacteria within the device to improve digestion of organic residues as well as to compete with algae for mineral nutrients, thereby preventing noxious blooms of plant material.

Abstract: A soil-based disposal trench that has failed from a biomat slime is recovered by adding a facultative anaerobic bacteria to an effluent that flows into the disposal trench. The facultative anaerobic bacteria consumes the biomat slime and, in one embodiment, supplants a strictly aerobic bacteria in the soil that converts nitrites to nitrates. As a result, the facultative anaerobic bacteria interrupt the conventional process of nitrification, changing the nitrites to nitrogen gas.
