SYSTEMS AND METHODS FOR TREATING OIL, FAT AND GREASE IN COLLECTION SYSTEMS
First Claim
1. A method of reducing fat, oil, and/or grease (FOG) in a FOG-contaminated wastewater collection system, the method being performed on-site at the FOG-contaminated wastewater collection system location and comprising the steps of:
- providing an on-site system for growing of FOG-degrading microbes at the FOG-contaminated wastewater collection system location, the on-site system comprising;
a main tank, an input for water, an output for a treatment batch, a mixing apparatus, and a temperature control apparatus;
depositing nutrient, water and an inoculum comprising FOG-degrading microbes into the on-site system;
growing the inoculum in the on-site system to provide a treatment batch comprising an increased number of the FOG-degrading microbes;
directly applying at least a portion of the treatment batch, said portion containing FOG-degrading microbes, to the FOG-contaminated wastewater collection system, such that the FOG-degrading microbes are not isolated, concentrated or freeze dried between the steps of growing and applying, and wherein the FOG-degrading microbes reduce FOG in the FOG-contaminated wastewater collection system; and
providing an aeration device, wherein the aeration device is placed on-site and adjacent to the FOG-contaminated wastewater collection system and the on-site system, the aeration device providing a sufficient aeration to agitate the surface of the wastewater in the FOG-contaminated wastewater collection system.

Abstract
The present invention relates to apparatus, methods, and applications for treating wastewater collection systems contaminated with fats, oils and grease (FOG), such as wet wells, transfer or lift stations, or main sewer lines, and more particularly to biological processes for removing the FOG from wastewater. This invention further relates to apparatus and methods for growing microbes on-site at a wastewater treatment facility or FOG-contaminated wastewater collection system location, and for economically inoculating sufficient microbes to solve various treatment problems rapidly.
