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 […]
Coagulation and Flocculation: Essential Steps in Water Purification Article Overview Article Type: Informational Primary Goal: Provide municipalities, water and wastewater engineers, plant operators, and equipment manufacturers with a technically detailed, practice-oriented guide to coagulation and flocculation in water treatment that supports design decisions, operator troubleshooting, chemical selection, pilot testing, and online process control. Who is […]
Introduction One of the most persistent challenges in municipal and industrial water treatment design is the accurate measurement of fluid velocity and volumetric flow under varying hydraulic conditions. Engineers often default to legacy specifications without re-evaluating the underlying technology, leading to significant lifecycle cost discrepancies. A surprising industry statistic suggests that up to 30% of […]
Introduction For municipal water distribution engineers, the battle against water age, nitrification, and biofilm formation is constant, particularly in dead-end mains and oversized distribution networks. The deployment of Automatic Flushing Systems (AFS) has shifted from a luxury to a regulatory necessity to maintain chlorine residuals and compliance with the Safe Drinking Water Act. However, the […]
INTRODUCTION Managing water age in distribution systems remains one of the most persistent challenges for municipal engineers. With the rising prevalence of chloramines and stricter regulations on Disinfection By-Products (DBPs), the “fill and forget” approach to distribution design is obsolete. Historically, manual flushing was the primary mitigation strategy, but rising labor costs and the need […]
UV Water Disinfection: A Proven Method for Safe Drinking Water Article Overview Article Type: Informational Primary Goal: Provide municipal decision makers, engineers, plant operators, and equipment manufacturers a technical, implementation-focused resource on ultraviolet water disinfection that explains how UV works, design and operational requirements, regulatory and validation expectations, and real-world deployment considerations to support specification, […]
Reverse Osmosis in Water Treatment: How It Works and Why It Matters In an age where clean and safe drinking water is more crucial than ever, reverse osmosis water treatment stands out as a powerful solution for ensuring water quality. This advanced filtration technology effectively removes contaminants, making it a popular choice for both home […]
Introduction One of the most persistent challenges facing municipal engineers today is the accurate monitoring of Combined Sewer Overflows (CSOs) and stormwater systems under regulatory consent decrees. The engineering challenge is multifaceted: equipment must survive in harsh, rag-prone environments, operate reliably during rapid hydraulic changes, and provide data accurate enough to satisfy environmental agencies. A […]
Introduction In wastewater treatment plant (WWTP) design, the clarifier is the hydraulic control center of the process, but its efficiency is entirely dependent on the accuracy of the feedback loops controlling it. A common challenge engineers face is the disconnect between mechanical clarification systems and the instrumentation required to optimize them. While mechanical failure is […]
Introduction to Ozone System Engineering Ozone generation is one of the most chemically potent yet operationally complex technologies in the water treatment arsenal. Unlike UV or chlorination, ozone is generated on-site, requiring a sophisticated integration of power supply, gas preparation, cooling thermodynamics, and mass transfer mechanics. For municipal and industrial engineers, the challenge is rarely […]
