Introduction One of the most frequent oversight areas in wastewater treatment plant (WWTP) design is the “last mile” of the solids handling process: moving dewatered cake from the centrifuge, belt press, or screw press to its final load-out point. Engineers often spend months optimizing the dewatering device itself, only to treat the conveyance system as […]
Introduction The Archimedes screw pump remains one of the oldest yet most efficient mechanisms for lifting water and wastewater. Despite the prevalence of centrifugal and submersible pump technologies, the screw pump maintains a critical position in municipal and industrial treatment plants, particularly in headworks (inlet lift stations), stormwater pumping stations, and return activated sludge (RAS) […]
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 In the complex hydraulic landscape of municipal and industrial water and wastewater treatment, the peristaltic pump—often referred to as a hose pump or tube pump—occupies a critical niche. Unlike centrifugal pumps that rely on kinetic energy, or other positive displacement pumps that utilize rotors, gears, or pistons, the peristaltic pump operates on the principle […]
1. Introduction In the hierarchy of municipal and industrial wastewater treatment processes, digestion systems occupy a critical role at the intersection of solids handling, pathogen reduction, and energy recovery. As facilities transition from traditional treatment plants to Water Resource Recovery Facilities (WRRFs), the anaerobic or aerobic digester transforms from a simple sludge stabilization tank into […]
Introduction For municipal and industrial engineers, few operational challenges are as persistent and costly as the fouling of pumping equipment. The modern wastewater stream has evolved significantly over the last two decades, with the proliferation of non-dispersible synthetics (wipes) and an increase in solids loading. Consequently, “ragging” has shifted from an occasional nuisance to a […]
Submersible sewage pumps play a crucial role in managing wastewater in homes, businesses, and municipal systems. These specialized devices are designed to handle the tough job of moving sewage and other waste-filled liquids from one place to another. They work tirelessly beneath the surface, often out of sight and out of mind. A submersible sewage […]
Non-clog centrifugal pumps are powerful tools in the world of fluid handling. These pumps are designed to move liquids containing solids without getting clogged. They work by using centrifugal force to push the fluid and any solid particles through the pump. Non-clog centrifugal pumps are built with special features that allow them to handle tough […]
Pumps play a crucial role in wastewater management systems. They move sewage and other liquid waste through pipes and treatment facilities. Wastewater pumps come in various types, each designed for specific applications and flow rates. These pumps handle everything from small residential systems to large municipal treatment plants. They must be tough enough to deal […]
How Much Electricity Does a Wastewater Treatment Plant Use? Introduction Water is an indispensable resource, and efficient wastewater treatment is critical for maintaining public health and environmental integrity. Wastewater treatment plants (WWTPs) are essential facilities designed to manage and treat sewage and industrial wastewater before it is discharged back into the environment. However, […]
