Abstract
Bioremediation of waste water traveling through a sewer system is accomplished by suspending in selected manholes a self-powered feeder device for delivering a desired amount of a solid microbial wastewater treatment preparation. The feeder device is preferably a) sealed to prevent moisture from causing caking or clumping of the solid microbial treatment preparation, b) controlled by a programable microprocessor and c) powered by a self-contained battery pack that allows the device to function for a desired period of time without maintenance or manual handling. Thus, the device performs automatically, maintains a flowable supply of the microbial treatment preparation and delivers a metered quantity of such microbial treatment preparation into waste water at a selected rate or at selected intervals, and at a treatment location that is upstream of a site where odor or grease build-up have become a problem, irrespective of whether the selected treatment site is devoid of electrical power, above-ground storage structure(s) and/or water supply.
