1. Introduction In the hierarchy of wastewater treatment unit processes, grit removal serves as the critical line of defense for downstream mechanical equipment and biological processes. Located at the headworks of a facility—typically immediately following coarse screening and raw sewage pumping—grit removal systems are tasked with the physical separation of inorganic solids from the waste […]
1. Introduction Biogas systems serve as the critical interface between anaerobic digestion processes and energy recovery or disposal mechanisms in municipal and industrial wastewater treatment facilities. While historically viewed merely as a waste byproduct requiring safe disposal, biogas—comprising primarily methane (CH4) and carbon dioxide (CO2)—is now universally recognized as a valuable renewable energy resource. The […]
1. Introduction Automation in the municipal water and wastewater sector serves as the central nervous system of critical infrastructure. Unlike discrete manufacturing, where systems function in controlled environments with predictable cycles, water and wastewater automation must contend with geographically dispersed assets, variable biological loading, hydraulic non-linearities, and harsh operating conditions. For consulting engineers, plant managers, […]
