INTRODUCTION Water and wastewater pump station failures, pipe ruptures, and operator injuries often trace back to a seemingly simple, yet notoriously misapplied component: the check valve. An incorrect valve selection at the pump discharge can lead to destructive water hammer, severe valve slam, chronic ragging, and premature mechanical failure. For consulting and utility engineers, understanding […]

Introduction For decades, the default solution for moving wastewater and sludge has been the non-clog centrifugal pump. However, as modern wastewater streams become increasingly burdened with fibrous materials (“flushable” wipes) and solids content rises due to enhanced thickening processes, the traditional centrifugal curve is often pushed to its limit. Engineers frequently encounter a critical decision […]

Introduction In municipal and industrial pumping systems, the selection of check valve technology is the primary defense against destructive hydraulic transients (water hammer) and reverse flow damage. Engineers are frequently faced with a divergent choice when specifying pump discharge control: specifying an active, electrically or pneumatically actuated solution (often synonymous with Rotork actuation on a […]

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, […]
