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, […]

ABB vs Emerson Instrumentation Equipment: Comparison & Best Fit Introduction One of the most persistent problems in water and wastewater design is the specification inertia that dictates instrumentation choices. Engineers replicate previous specifications without re-evaluating whether the technology has evolved or whether the application demands have shifted. A meaningful share of minor process deviations trace […]

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 […]

Aeration system wastewater installations typically consume 45 to 60 percent of a municipal treatment plant energy budget and determine whether biological processes meet effluent nitrogen and BOD targets. This guide gives plant managers, process engineers, and operators a practical roadmap for selecting, designing, operating, retrofitting, and maintaining aeration system wastewater installations to maximize oxygen transfer […]

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 […]

Cla-Val vs Crane Hydrant Flushers Equipment: Comparison & Best Fit Introduction For municipal distribution engineers, the battle against water age, nitrification and biofilm formation is constant, particularly in dead-end mains and oversized networks. Automatic flushing systems have shifted from a convenience to a practical necessity for maintaining chlorine residuals and meeting drinking water compliance obligations. […]

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 regulation of disinfection by-products, 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 for consistent residual […]

Understanding Nitrification and Denitrification in Wastewater Treatment Meeting tight effluent nitrogen limits demands a clear grasp of the nitrification and denitrification sequence and how it responds to changing loads, temperature and carbon availability. This guide unpacks the microbial pathways and stoichiometry behind ammonia oxidation and nitrate reduction, provides design and operating ranges for solids retention […]

Emerson vs Badger Meter Horizontal End Suction Pumps Equipment Introduction A pump station’s integrity relies not just on the hydraulic mover but on the control architecture that governs it. Engineers focus intensely on the pump curve and frequently overlook the specification of the control and measurement layer attached to the discharge. That oversight produces integration […]

Badger Meter vs Endress+Hauser Horizontal End Suction Pumps Equipment Introduction In municipal and industrial fluid handling, the horizontal end suction centrifugal pump is the workhorse of the facility. But the pump is only as effective as the control loop that governs it. Engineers expend significant effort selecting the pump hydraulic curve and routinely undervalue the […]
