Chlorine Disinfection for Water Treatment: Safety and Effectiveness Article Overview Article Type: Informational Primary Goal: Provide municipal water and wastewater engineers and operators a technical, implementation-focused reference on chlorine disinfection that covers how chlorine inactivates pathogens, key performance metrics, design and operational requirements, safety and emergency planning, disinfection by-product management, monitoring strategies, and decision criteria […]
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 […]
Biosolids Management: Best Practices for Treatment Plants Article Overview Article Type: How-To Guide Primary Goal: Provide treatment plant operators, engineers, and municipal decision makers with a practical, technically detailed roadmap for designing, operating, monitoring, and financing biosolids management systems that meet regulatory requirements, control risk, and maximize resource recovery. Who is the reader: Municipal wastewater […]
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 […]
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 water and wastewater design is the “specification inertia” that dictates instrumentation choices. Engineers often replicate previous specifications without re-evaluating whether the technology has evolved or if the application demands have shifted. A staggering number of process upsets—estimates suggest up to 40% of minor deviations—can be traced back […]
Introduction In the municipal and industrial water sectors, the accuracy of flow measurement directly correlates to the operational efficiency of pumping systems. A common challenge facing design engineers is the disconnect between the mechanical performance of pumps and the instrumentation used to monitor them. When specifying flow measurement technologies to monitor pumping assets, the choice […]
Wastewater Aeration Systems: Improving Treatment Efficiency Article Overview Article Type: How-To Guide Primary Goal: Give municipal decision makers, plant designers, and operators a practical, technically rigorous roadmap for selecting, designing, operating, retrofitting, and maintaining aeration system wastewater installations to maximize treatment performance and minimize energy and lifecycle costs. Who is the reader: Municipal utility managers, […]
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 […]
