Introduction One of the most dangerous misconceptions in hydraulic engineering is the attempt to apply centrifugal pump logic to positive displacement equipment. Engineers trained to identify the Best Efficiency Point (BEP), check for runout, and evaluate shutoff head on a standard curve often find themselves disoriented when presented with a peristaltic (hose) pump performance chart. […]
Introduction The operational resilience of a wastewater treatment plant or lift station is often determined not by its pumps, but by the equipment protecting them. With the rise of “flushable” wipes and non-dispersible textiles entering municipal collection systems, the phenomenon of ragging has transitioned from a nuisance to a critical operational failure mode. Industry data […]
Introduction For municipal and industrial wastewater engineers, the management of solids—specifically the reduction of ragging, stringy materials, and debris—remains one of the costliest operational challenges. Unscheduled downtime due to clogged pumps or damaged downstream instrumentation costs utilities millions annually in labor and equipment replacement. When evaluating solids reduction technologies, engineers often face a critical fork […]
Introduction One of the most persistent inefficiencies in modern wastewater treatment plants is the misapplication of mixing energy. While aeration systems typically consume the lion’s share of plant power, submersible mixers often operate continuously in anoxic zones, sludge holding tanks, and equalization basins, accumulating massive lifecycle costs. A surprising industry statistic suggests that up to […]
