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 Clarification is the fundamental unit operation in water and wastewater treatment, serving as the primary method for gravity separation of suspended solids from liquid. In municipal and industrial applications, clarification equipment—often referred to as sedimentation tanks, settling basins, or clarifiers—operates on the principles of density difference and Stokes’ Law to settle particulate matter […]
1. Introduction In the hydraulic architecture of municipal and industrial water systems, automatic valves function as the primary logic gates for hydraulic control. Unlike isolation valves (gate, butterfly, ball) which are static in their operation (either open or closed), automatic valves are dynamic, modulating devices designed to regulate pressure, flow, level, or surge conditions autonomously. […]
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 […]
Introduction In municipal water distribution and industrial fluid handling, the management of reservoir and tank levels is a critical operational requirement. The altitude valve serves as the primary mechanical safeguard against overflows and the central mechanism for maintaining the hydraulic grade line within a specific pressure zone. These valves are specialized automatic control valves (ACVs) […]
Membrane Filtration Technology for Advanced Wastewater Treatment Overview of Membrane Filtration Processes When it comes to membrane filtration wastewater, we're not just talking about a fancy way to filter out the bad stuff — we're talking about a revolution in how we treat water. Did you know that over 80% of global wastewater is released […]
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- […]
Designing and Operating Efficient Effluent Treatment Plants Regulatory Framework and Compliance in Effluent Treatment Navigating the labyrinth of regulations surrounding effluent treatment plants can feel like trying to find a needle in a haystack—if that haystack were also on fire. With stringent environmental standards and compliance requirements, every wastewater treatment operator must be on their […]
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 […]
