Introduction to Double Disc Technology in Wastewater One of the most persistent challenges in municipal and industrial wastewater treatment is the reliable handling of thixotropic, abrasive, and rag-laden fluids. Engineers frequently grapple with the premature failure of progressive cavity (PC) pump stators or the ragging of centrifugal impellers in grit and scum applications. While many […]

1. INTRODUCTION In the complex hydraulic architecture of municipal water and wastewater treatment plants, water control gates serve as the primary mechanism for flow isolation, level control, and directional diversion. Unlike pumps or blowers, which are active energy consumers, control gates are often passive static equipment until called upon. However, their role is foundational to […]

  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 […]

Introduction to Split Case Pumps in Water and Wastewater Infrastructure In the hierarchy of municipal and industrial hydraulic machinery, the split case pump stands as the predominant choice for high-flow, low-to-medium head applications. Characterized by a casing that is split parallel to the shaft axis (axially split) or perpendicular to it (radially split), this pump […]

Certified PFAS Removal Products: An Expert Guide for Water Treatment Solutions Introduction Per- and polyfluoroalkyl substances (PFAS), commonly referred to as "forever chemicals," have emerged as a critical environmental issue due to their persistent presence in water systems and associated health risks. As of July 2025, regulatory frameworks and technological advancements in PFAS remediation are […]

PFAS Communication Plan for Utilities Introduction Per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals," are gaining increased scrutiny across the United States due to their persistent and detrimental impact on public health and the environment. As regulations intensify and consumer awareness grows, utilities must devise a robust PFAS Communication Plan. This guide provides […]

Understanding the Cost to Comply with PFAS MCL: A Comprehensive Exploration Introduction As of July 30, 2025, the regulatory landscape surrounding per- and polyfluoroalkyl substances (PFAS) has reached a critical juncture, notably with the establishment of Maximum Contaminant Levels (MCLs) by the U.S. Environmental Protection Agency (EPA). Municipalities and industries alike are grappling with the […]

Emerging PFAS Compounds: Understanding the New Frontiers in Contamination and Remediation Introduction Per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals,” are a class of synthetic compounds that have garnered increasing scrutiny over the past decade. With more than 4,700 variants identified, the public health implications of these compounds are stark. Recent concerns […]

PFAS Filtration Systems for Home: A Comprehensive Guide Introduction Per- and polyfluoroalkyl substances (PFAS) have garnered significant attention in recent years due to their ubiquitous presence in water supplies and potential health risks. As emerging contaminants, PFAS are linked to various health concerns such as cancer, liver damage, and immune system disruption. With increasing regulatory […]

Comprehensive Water and Wastewater Treatment Design Guide Regulatory Framework and Compliance Standards Navigating the maze of regulations surrounding the treatment of water and wastewater can feel like trying to find your way through a cornfield blindfolded. With over 40 federal regulations and countless state laws, it’s no wonder that municipalities often feel overwhelmed. In fact, […]
