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 […]

Effective Solids Management Strategies in Wastewater Treatment Understanding the Composition of Wastewater Solids Municipal wastewater solids are typically 60 to 80 percent volatile, meaning organic, depending on the mix of primary and waste activated sludge and the amount of grit and inert material reaching the plant. This article sits within our coverage of solids and […]

Reverse Osmosis Systems for Industrial Wastewater Reuse Technical Mechanisms of Reverse Osmosis in Wastewater Treatment Reverse osmosis wastewater treatment isn’t just a fancy term thrown around in engineering circles; it's a game-changer. Did you know that reverse osmosis can remove up to 99% of dissolved salts and contaminants from water? That’s not just a stat […]

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. Reuse is in fact far lower than that: […]

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. This article sits within our coverage of denitrification in wastewater treatment. The numbers that govern the process: nitrification consumes about […]

Understanding the Importance of Effluent Treatment Plants Regulatory Framework Governing Effluent Treatment Did you know that over 80% of the world's wastewater is released into the environment without adequate treatment? This alarming statistic highlights the critical need for robust regulatory frameworks governing effluent treatment plants (ETPs). Without these regulations, we’d be swimming in a toxic […]

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 […]

Designing and Operating Efficient Effluent Treatment Plants Introduction An effluent treatment plant is judged on two things that are easy to state and difficult to deliver simultaneously: does the discharge meet permit, and does it do so at a cost the utility or industrial owner can sustain year after year. Plants that satisfy the first […]

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 […]

Understanding PFAS Contamination: What Municipalities Need to Know Introduction PFAS contamination has moved from an emerging concern to an operational reality for water utilities across the country. Municipalities that a decade ago had never sampled for these compounds now face enforceable drinking water limits, public scrutiny, and capital decisions measured in millions of dollars. This […]
