Understanding PFAS Chemicals: The Hidden Threat to Clean Water Chemical Properties and Classification of PFAS When it comes to PFAS chemicals, the term forever chemicals isn't just a catchy nickname; it's a stark reality. These substances can linger in the environment for decades, making them a persistent challenge for water treatment facilities. In fact, studies […]
1. Introduction: The Role of Progressive Cavity Pumps in Water & Wastewater In the complex hydraulic architecture of municipal and industrial water treatment facilities, the Progressive Cavity (PC) pump—often referred to as a helical rotor pump or eccentric screw pump—occupies a critical operational niche. Unlike centrifugal pumps, which rely on kinetic energy to move fluid […]
Introduction For municipal and industrial engineers, the centrifugal pump is the heartbeat of water conveyance and treatment infrastructure. However, a staggering number of pump installations fail to meet their expected lifecycle due to specification errors rather than manufacturing defects. Industry statistics suggest that over 60% of pump failures are attributed to operating outside the Preferred […]
Introduction The vertical turbine pump (VTP) serves as a cornerstone of fluid movement in municipal water and wastewater infrastructure. Unlike horizontal pumps, which require significant floor space and rely on positive suction head often provided by gravity or booster systems, vertical turbine pumps are designed to operate submerged, utilizing the fluid source itself to provide […]
Advanced Filtration Technologies for Wastewater Treatment Systems Overview of Filtration Technologies in Wastewater Treatment Imagine a city where every drop of water is cherished, not wasted. In the U.S. alone, nearly 80% of wastewater is treated and returned to the environment, but only about 20% is reused. This startling statistic highlights not just the importance […]
Understanding the Nitrification and Denitrification Process in Wastewater Treatment Biochemical Foundations of Nitrification Nitrification isn’t just a fancy term for removing nitrogen; it’s an intricate biochemical ballet that plays a crucial role in wastewater treatment. Think of it as the unsung hero of the nitrification denitrification process, tirelessly working behind the scenes to ensure our […]
Understanding PFAS Chemicals and Their Impact on Water Quality Chemical Properties and Classification of PFAS Did you know that certain PFAS chemicals can take over a thousand years to break down in the environment? That’s right—while your leftovers might spoil in a week, these persistent chemicals are here for the long haul. PFAS, or per- […]
Understanding PFAS Contamination: What Are Forever Chemicals? Chemical Properties and Classification of PFAS PFAS, or per- and polyfluoroalkyl substances, are not your run-of-the-mill chemicals. These notorious compounds have a unique ability to repel both water and grease, making them a favorite in everything from non-stick cookware to waterproof clothing. But here's the kicker: they’re also […]
Under Sink PFAS Filters: Essential Defense Against Contaminants Introduction Per- and polyfluoroalkyl substances (PFAS) have emerged as some of the most concerning contaminants in water supplies across the United States and globally. These "forever chemicals," known for their durability and resistance to degradation, have been linked to a range of health issues, including cancers, liver […]
Understanding PFAS Contamination: What Municipalities Need to Know Sources and Pathways of PFAS Contamination Did you know that over 95% of Americans have detectable levels of PFAS in their blood? That's not just a statistic; it's a wake-up call for municipalities grappling with the pervasive nature of PFAS contamination. These pesky chemicals, often dubbed forever […]
