Abstract

A method of treating wastewater prior to being processed within a wastewater treatment facility is provided, wherein the wastewater is delivered to the wastewater treatment facility by a collection piping system having an interior surface, and wherein the wastewater includes a predominant waste material, the method comprising: introducing select microbes into the piping system in an amount proportional to the surface area of the interior surface of the piping system, wherein the select microbes are capable of completely consuming the predominant waste material in the wastewater, until a biomass comprising almost entirely the select microbes is formed along the interior surface of the piping system; monitoring the biological oxygen demand (BOD) level of the wastewater at a downstream location immediately prior to the wastewater treatment facility in comparison to a desired BOD level; and adjusting the introduction of the select microbes into the piping system in proportion to the average downstream flowrate of the wastewater through the piping system to minimize the difference between the monitored BOD level and the desired BOD level.
