INTRODUCTION Catastrophic force main failures caused by hydraulic transients (water hammer) remain one of the most costly and environmentally damaging events a municipal utility or industrial wastewater plant can experience. When pumps suddenly trip due to power failure, the resulting surge wave can spike system pressures to multiple times their design limit, rupturing pipes, blowing […]

INTRODUCTION One of the most frequent, yet easily preventable, failure points in municipal and industrial treatment facilities occurs at the very bottom of chemical storage and settling tanks. When a bottom-drain valve fails to seat properly, binds due to corrosion, or leaks hazardous chemical sludge into secondary containment, engineers are forced into emergency response modes. […]

INTRODUCTION For municipal and industrial plant engineers, few sounds on a facility floor are as universally dreaded as the distinct, aggressive crackle of “gravel” flowing through a clean water or wastewater pipeline. This phenomenon is rarely harmless acoustic feedback; it is the destructive hallmark of fluid vaporization and collapse. When addressing Misc. Valves Cavitation and […]

Gravity water filtration offers a straightforward way to cut pumping energy and improve system resilience when site head and treatment goals align. This how-to guide gives engineers and plant operators step-by-step low-energy design strategies, retrofit pathways, and the instrumentation and performance metrics needed, including numeric ranges, headloss calculation approaches, and a worked example. Read on […]

INTRODUCTION One of the most destructive forces in municipal and industrial fluid handling is the rapid formation and collapse of vapor bubbles within a liquid stream. When evaluating Anti-Cavitation for Slurry and High-Solids Service: What Works and What Fails is a critical distinction that dictates the lifecycle of pumping and valving infrastructure. Standard clear-water cavitation […]

When a gould pump goes down at a municipal station the consequences are immediate: bypasses, regulatory headaches, and costly emergency repairs. This hands-on guide shows operators and engineers how to translate a wastewater duty point into the right Goulds model, size and commission the pump with proper NPSH margin, implement preventive maintenance and condition monitoring, […]

INTRODUCTION One of the most common and destructive phenomena operators experience in municipal and industrial pumping systems is the unmistakable sound of gravel passing through the piping. While engineers frequently attribute this acoustic signature to pump issues, the true root cause often lies just upstream. When investigating Strainers Cavitation and Noise: Causes typically track back […]

1. INTRODUCTION The presence of soluble organic compounds in municipal and industrial wastewater represents one of the most significant engineering challenges in environmental treatment systems. Soluble organics, unlike particulate matter, cannot be removed through simple physical separation techniques such as screening, settling, or basic filtration. Because these contaminants are dissolved in the aqueous phase, their […]

1. INTRODUCTION The presence of soluble organic compounds in industrial and municipal wastewater represents one of the most critical challenges in environmental engineering. Unlike particulate organics, which can be mechanically separated via screening, sedimentation, or dissolved air flotation (without coagulation), soluble organics are fully dissolved in the aqueous phase. Their removal requires phase-change mechanisms, chemical […]

INTRODUCTION One of the most destructive and frequently misunderstood phenomena in municipal and industrial water systems is the hydraulic transient, commonly known as water hammer. When a pump suddenly loses power, or a valve closes too quickly, the kinetic energy of the moving fluid column is abruptly converted into pressure energy. This generates high-velocity pressure […]
