INTRODUCTION The handling of thickened sludge, grit, and high-solids wastewater represents one of the highest Operational Expenditure (OPEX) categories in modern treatment facilities. Engineers are frequently tasked with selecting positive displacement technology that balances hydraulic efficiency with solids handling capability. A single misapplication in this part of the process—such as specifying a pump with inadequate […]
Introduction: The Role of Flow Control Infrastructure in Municipal Systems In the hydraulic architecture of municipal water and wastewater treatment plants, water control gates serve as the primary mechanisms for flow isolation, modulation, and diversion. Unlike standard process valves which typically handle pressurized flow within piping networks, control gates—ranging from heavy-duty cast iron […]
PFAS and Water Softeners: Understanding the Implications for Water Treatment Introduction As water quality emerges as a pressing global concern, the presence of per- and polyfluoroalkyl substances (PFAS) in water supplies has become a contentious issue. These "forever chemicals," resistant to degradation and linked to various health risks, have led to significant regulatory scrutiny and […]
PFAS Screening Methods: An Expert Guide for Environmental Professionals Introduction Per- and polyfluoroalkyl substances (PFAS) have garnered significant attention over recent years, primarily due to their persistence in the environment and human health implications.
