Designing and Operating Efficient Effluent Treatment Plants Regulatory Framework and Compliance Standards Did you know that nearly 40% of U.S. wastewater treatment plants are struggling to meet regulatory requirements? That's a staggering figure, especially when you consider the critical role these facilities play in protecting public health and the environment. If you're operating an effluent […]
Introduction: The Role of AODD Pumps in Water & Wastewater Infrastructure In the complex hydraulic architecture of municipal and industrial water and wastewater treatment plants, centrifugal pumps often command the most attention due to their volume handling capabilities. However, Air-Operated Double Diaphragm (AODD) pumps serve as the critical auxiliary workhorses that enable the precise handling […]
Introduction to PLC & Control Platforms in Water & Wastewater In the municipal and industrial water sector, the Programmable Logic Controller (PLC)—often evolving into the Programmable Automation Controller (PAC)—serves as the central nervous system of treatment and distribution infrastructure. Unlike discrete manufacturing, where systems may shut down for retooling, water and wastewater treatment plants (WTPs […]
Introduction The escalation of non-dispersible solids in municipal wastewater streams—colloquially known as the “flushable wipes” crisis—has fundamentally altered how consulting engineers and utility directors approach pump station design. A decade ago, 3-inch solids handling capacity was sufficient for most municipal lift stations. Today, the tensile strength of modern synthetic fibers creates roping and matting that […]
Managing Water Treatment Waste: Best Practices for Environmental Compliance Regulatory Framework for Water Treatment Waste Navigating the regulatory maze surrounding water treatment waste can feel like trying to find your way through a cornfield blindfolded. With an estimated 80% of the world's wastewater being discharged without treatment, the stakes are higher than ever for municipalities […]
Introduction In municipal and industrial water and wastewater systems, the check valve serves a critical, albeit often understated, function: the prevention of reverse flow. While the fundamental concept—allowing flow in one direction while blocking it in the other—appears simple, the engineering reality is complex. Check valves are the primary defense against pump reversal, which can […]
1. Introduction Rotary lobe pumps represent a critical category of positive displacement (PD) equipment within the water and wastewater infrastructure. Unlike centrifugal pumps, which rely on kinetic energy to move fluid, rotary lobe pumps utilize the mechanical action of counter-rotating elements to trap and displace discrete volumes of fluid. This fundamental difference in operating principle […]
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 […]
Introduction In the landscape of municipal and industrial water and wastewater infrastructure, the butterfly valve represents one of the most ubiquitous and critical components for flow control and isolation. Characterized by a quarter-turn rotary motion and a relatively compact footprint, butterfly valves are utilized across a vast spectrum of applications—from raw water intake and high-pressure […]
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 […]
