1. Introduction In the hierarchy of municipal and industrial wastewater treatment processes, digestion systems occupy a critical role at the intersection of solids handling, pathogen reduction, and energy recovery. As facilities transition from traditional treatment plants to Water Resource Recovery Facilities (WRRFs), the anaerobic or aerobic digester transforms from a simple sludge stabilization tank into […]

Introduction In the municipal and industrial water treatment sectors, the selection of positive displacement (PD) pumping technology is often the determining factor between a reliable, low-maintenance process and a chronic operational headache. Engineers frequently default to familiar technologies without fully analyzing the rheological impacts of the fluid on the equipment lifecycle. A common, yet critical, […]

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 […]

1. Introduction In the municipal water and wastewater sector, the “nervous system” of any treatment facility or distribution network is its automation system. While Programmable Logic Controllers (PLCs) and HMI software provide the raw computing power and visualization, the successful implementation of these technologies relies heavily on the Systems Integrator (SI) or the Automation System […]

1) INTRODUCTION A staggering 60% of pump failures in municipal and industrial wastewater facilities are attributed not to mechanical defects, but to misapplication—selecting the wrong technology for the hydraulic and rheological conditions. Engineers frequently face a critical decision point when designing chemical feed systems, sludge transfer lines, or difficult process fluid loops: should they specify […]

Introduction In the hierarchy of treatment plant equipment, flow control gates are often treated as static commodities rather than dynamic machinery. This is a critical error. While a pump failure may stop flow, a gate failure can result in catastrophic flooding, bypass events, regulatory fines, and process upsets that compromise the entire plant. A surprising […]

Introduction For municipal and industrial treatment plant engineers, sludge handling often represents the single largest line item in the operational budget. With biosolids disposal costs frequently accounting for 30% to 50% of a facility’s total operating expenses, the efficiency of the dewatering process is not merely a technical detail—it is a critical financial lever. A […]

Introduction For municipal and industrial engineers, few operational challenges are as persistent and costly as the fouling of pumping equipment. The modern wastewater stream has evolved significantly over the last two decades, with the proliferation of non-dispersible synthetics (wipes) and an increase in solids loading. Consequently, “ragging” has shifted from an occasional nuisance to a […]
