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 […]
Location: 8800 S Claiborne Ave, New Orleans, LA 70118Operating Authority: Sewerage and Water Board of New Orleans (SWBNO) FACILITY BASIC INFORMATION Plant Name: Carrollton Water Purification Plant Location: New Orleans, Orleans Parish, Louisiana Operating Authority: Sewerage and Water Board of New Orleans (SWBNO) Design Capacity: 232 MGD (Million Gallons per Day) Current Average Flow: ~135 […]
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 […]

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and stricter regulations on Disinfection By-Products (DBPs), the “fill and forget” approach to distribution design is obsolete.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 […]

Understanding Nitrification and Denitrification in Wastewater Treatment Meeting tight effluent nitrogen limits demands a clear grasp of the nitrification denitrification process and how it responds to changing loads, temperature, and carbon availability. This practical guide unpacks the microbial pathways and stoichiometry behind ammonia oxidation and nitrate reduction, provides numeric design and operating ranges for SRT, […]
Introduction In municipal and industrial fluid handling, the integrity of a pump station relies not just on the hydraulic mover, but on the monitoring and control loop that governs it. A surprising statistic in water utility management reveals that up to 30% of pump efficiency loss is masked by inaccurate discharge monitoring, leading to undetected […]
