Wastewater gas reduction method

Abstract

A method of reducing undesirable gases in a wastewater collection piping system is provided, comprising the introduction of select microbes into the piping system at a frequency corresponding to the pumping activity of the pumping stations, and 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; and wherein an anaerobic biomass comprising almost entirely the select microbes is formed along the interior surface of the piping system. In the foregoing method, the select microbes are preferably non-pathenogenic and may be introduced in an initially non-active state. Furthermore, the select microbes may also be capable of functioning in either an aerobic or an anaerobic manner. In a more preferred embodiment, the level of nitrogen in the piping system is monitored, and the introduction of the select microbes is adjusted to maintain at least 0.1 mg/l of total nitrogen in the wastewater. Optionally, a predetermined quantity of ozone may be introduced into the piping system at selected locations to further reduce the presence of the undesirable gases.
