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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
