1. Introduction In the hydraulic architecture of municipal and industrial wastewater systems, continuity of service is the paramount directive. While permanent infrastructure—lift stations, treatment plants, and gravity mains—forms the backbone of these systems, the ability to bypass these components during failure, maintenance, or rehabilitation is a critical engineering requirement. Emergency bypass and temporary pumping systems […]

Introduction For municipal and industrial wastewater engineers, the protection of downstream process equipment—pumps, valves, centrifuges, and digesters—starts at the headworks. The improper reduction of solids or the inefficient separation of inorganic grit can lead to catastrophic pump cavitation, seal failures, and the rapid accumulation of rag balls in digesters that necessitates expensive cleanouts. When specifying […]

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. These synthetic chemicals, often referred to as “forever chemicals,” are ubiquitous in a variety of products, from non-stick cookware to firefighting […]

PFAS Analytical Methods: Understanding the Current Landscape and Implications for Environmental Safety Introduction Per- and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals,” have gained significant attention due to their widespread environmental presence and potential health risks. With mounting evidence linking PFAS to adverse human health effects, regulatory agencies are under increasing pressure to monitor […]
