Anoxic Zones in Wastewater Treatment: Nitrogen Removal Explained Article Overview Article Type: Informational Primary Goal: Explain how anoxic zone treatment removes nitrogen in municipal and industrial wastewater, covering microbial mechanisms, common process configurations, design and operational parameters, monitoring and control strategies, retrofit options, technology vendors, and real world examples so engineers and operators can design, […]

Chlorine Disinfection for Water Treatment: Safety and Effectiveness Chlorine disinfection water remains the workhorse for municipal drinking and wastewater systems because it delivers rapid inactivation of many pathogens and a persistent distribution residual. This article gives engineers and operators practical, implementation-focused guidance on how chlorine inactivates organisms, CT calculations with worked examples, dosing and contact […]

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, […]
