Both municipal WWTP operators and commercial facility managers have had limited options for solutions to handle the growing problem of solids in wastewater. Screening is typically recommended to protect pumps and other equipment from debris-laden influent sewage, including automated vertical-bar screen rakes. Screening systems, however, have limited effect with inhibiting these new solids from reaching pumps within the treatment plant. Grinders, shredders and choppers have been installed prior to pumps to reduce the size of the solids. However, these options are confronted with space constraints in both municipal and commercial pump lift stations, as well as significant costs for this additional equipment.
