Introduction One of the most insidious threats to the longevity of large-scale pumping systems is the phenomenon of air entrainment caused by intake vortices. For municipal and industrial engineers, the challenge is compounded when geotechnical constraints force the use of deep, circular containment structures. Diaphragm Wet Well Design and Minimum Submergence to Prevent Vortexing is […]

Introduction Chemical dosing accuracy is the silent guardian of water quality compliance and the hidden driver of operational expenditure. In municipal and industrial treatment plants, the failure to properly understand hydraulic behavior results in millions of dollars lost annually to chemical waste, premature equipment failure, and process instability. A surprising industry statistic suggests that over […]

Chlorine Disinfection for Water Treatment: Safety and Effectiveness Chlorine disinfection water remains the workhorse for municipal drinking and wastewater systems because it delivers rapid inactivation of many pathogens and a persistent distribution residual. This article gives engineers and operators practical, implementation-focused guidance on how chlorine inactivates organisms, CT calculations with worked examples, dosing and contact […]

Introduction In municipal wastewater treatment and industrial sludge handling, the premature failure of progressive cavity (PC) pump stators remains one of the most persistent and costly maintenance burdens. Engineers frequently specify robust hydraulic conditions, yet the interface between the pump mechanics and the electrical control system is often where reliability disintegrates. A startling volume of […]

Introduction One of the most frequent points of failure in municipal pumping infrastructure involves the misapplication of pump geometry to the wet well environment. While submersible non-clog pumps dominate small to medium sewage lift stations, engineers frequently turn to vertical turbine pumps (VTPs) for high-flow, high-head, or footprint-constrained applications. However, a staggering number of these […]

Biosolids Management: Best Practices for Treatment Plants Biosolids management is where regulatory pressure, operational cost, and community risk collide—get the decisions right and you control disposal costs and recover resources; get them wrong and you face fines, complaints, and rising hauling bills. This practical guide gives treatment plant operators and engineers a technical roadmap for […]

Introduction The failure of a chemical feed system or sludge transfer unit in a water treatment plant often isn’t caused by a defective pump; it is caused by a failure in the commissioning process. In municipal and industrial applications, up to 60% of early-life equipment failures can be traced back to improper installation, inadequate pipe […]

INTRODUCTION One of the most persistent causes of premature equipment failure in municipal and industrial fluid handling systems is the disconnect between the design point and the actual operating reality. Engineers frequently specify pumps for a peak flow condition that occurs less than 5% of the time, leaving operators to manage equipment that runs inefficiently—and […]

Introduction to Intake Hydraulics For municipal and industrial engineers, the physical geometry of a pump station is often treated as secondary to the selection of the pump itself. However, industry data suggests that nearly 30% of premature pump failures—manifesting as vibration, cavitation damage, and bearing wear—are directly attributable to poor intake conditions rather than mechanical […]

Coagulation and Flocculation: Essential Steps in Water Purification Coagulation flocculation water treatment is the frontline process that decides whether downstream filtration, membranes and disinfection will meet turbidity and DBP precursor targets. This article turns coagulation chemistry into practical decisions—coagulant and polymer selection, rapid mix and flocculation G and time ranges, jar testing and pilot methods, […]
