Abstract
This invention provides a methodology for rapid biofilm formation in a pilot drain system. In a typical embodiment, aqueous nutrient medium and an inoculum comprising both Sphaerotilus natans and natural biofilm bacteria is utilized to promote growth of a biofilm mass which occupies at least about 20 percent of the conduit volume of a pilot drain system within a time period of about two weeks under simulated drain usage conditions.
