Cutting Sewage Problems Down To Size

For the past 10 to 15 years, wastewater treatment operators have faced increased clogging issues related to baby wipes, disposable diapers, rags, and other foreign debris. At the same time, the use of low-flow toilets has increased the solids concentration of sewage flow. This discussion with Brad Jernigan and Christina Foster from Pentair addresses differences between how grinder pumps (low flow/high head) and chopper pumps (higher flow/lower head) can benefit that situation. They also compare the advantages of how axial-cutter design vs. radial-cutter design can aid in shredding large debris, bit by bit, without sucking it into the body of the pump where it can clog and shut down the unit.
