Introduction One of the most common, yet catastrophic, oversight errors in municipal water and industrial wastewater treatment plants occurs at the chemical feed skid. Engineers often spend countless hours specifying the perfect metering pump or chemically inert control valve, only to default to standard-issue automation. When dealing with highly corrosive substances like sodium hypochlorite, ferric […]
Clark County water reclamation serves as a practical blueprint for municipalities facing stricter effluent limits, aging infrastructure, and tight budgets by tracing permitting strategy, technology choices, phased construction and operational handover. This case study delivers concrete timelines, commissioning and operator training checklists, vendor trade offs, and measurable KPIs practitioners can adapt for medium to large […]
INTRODUCTION: THE HIDDEN COST OF CAVITATION IN WASTEWATER For municipal consulting engineers and plant operators, the distinct “gravel rattling” sound emanating from a pump volute or control valve is a familiar and costly warning. Cavitation—the formation and violent collapse of vapor bubbles within a fluid—accounts for up to 30% of premature equipment failures in severe […]
The halo 5 water system is a UV-based treatment platform many utilities are evaluating for potable, reuse, and tertiary disinfection applications. This article delivers a technical breakdown of its architecture, hydraulics, lamp and control characteristics, and how delivered UV dose performs under representative water qualities, with head-to-head context against TrojanUV, Xylem Wedeco, and Evoqua. For […]
When a municipal operator must specify a point-of-use or small-scale treatment option, choosing the right water filter katadyn product matters as much for operations and regulatory compliance as it does for capital cost. This article compares Katadyn ceramic microfilters, cartridge systems with activated carbon, and hollow fiber modules, quantifying removal mechanisms, flow and head loss, […]
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 […]
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 […]
Effective sand filtration is where plant performance, operating cost, and regulatory compliance meet—or fail. This practical playbook gives municipal and industrial plant engineers and operators step-by-step sizing calculations in metric and imperial, media specifications, backwash strategies, monitoring setpoints, and a troubleshooting checklist with worked examples. Expect manufacturer-referenced ranges and field-testable fixes you can apply during […]
Activated Carbon Filtration: Removing Contaminants from Water Article Overview Article Type: Informational Primary Goal: Provide municipal engineers, wastewater treatment operators, plant designers, and equipment manufacturers with a technical, implementation-focused guide to activated carbon filtration covering mechanisms, contaminant scope, design calculations, operational practices, monitoring, regeneration and disposal options, vendor selection, and real-world performance data so they […]
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, […]
