Introduction In the modern era of wastewater infrastructure, the shift toward submersible pumping technology has been substantial. However, a significant percentage of municipal lift stations and treatment plants rely on the durability and accessibility of conventional dry pit pumps. Engineers frequently overlook the long-term operational benefits of separating the driver from the hydraulic fluid, particularly […]
Last Updated: October 2023 1. Introduction Louisiana’s wastewater infrastructure operates within one of the most hydro-geologically complex environments in the United States. Managing treatment capacity in a state defined by high water tables, subsidence, and significant industrial activity presents unique challenges for utility managers and consulting engineers. The state’s infrastructure is overseen by the Louisiana […]
1. Introduction In municipal and industrial wastewater treatment, the management of odors is not merely an aesthetic concern; it is a critical operational parameter that impacts regulatory compliance, community relations, facility safety, and infrastructure longevity. Odor Control Systems (OCS) represent the primary defense against the release of nuisance compounds—principally hydrogen sulfide (H2S), mercaptans, ammonia, and […]
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, […]
PFAS Environmental Monitoring: A Comprehensive Guide to Current Practices and Future Directions Introduction As concerns over the impact of per- and polyfluoroalkyl substances (PFAS) on human health and the environment continue to mount, effective environmental monitoring has become a crucial component of regulatory frameworks and public health initiatives. The urgency of this issue cannot be […]
GAC Reactivation for PFAS: A Comprehensive Solution for Water Treatment Introduction As global awareness increases regarding per- and polyfluoroalkyl substances (PFAS) and their detrimental effects on public health and the environment, the need for effective treatment solutions has become a pressing concern for water treatment facilities. Granular Activated Carbon (GAC) systems have emerged as a […]
