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.
