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 […]
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 […]
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 escalation of non-dispersible solids in municipal wastewater—specifically the “ragging” phenomenon caused by synthetic wipes—has transformed solids reduction from a luxury to a necessity. For consulting engineers and plant operators, the failure to adequately protect downstream pumps and dewatering equipment results in catastrophic downtime. Industry data suggests that unscheduled maintenance due to ragging […]
Introduction For municipal and industrial treatment plant engineers, solids handling frequently represents the single largest operational cost center, often accounting for 40% to 50% of total plant O&M budgets. While liquid stream processes often garner the most design attention, the failure to properly specify dewatering equipment creates a bottleneck that can jeopardize regulatory compliance […]
Effective Solids Management Strategies in Wastewater Treatment Understanding the Composition of Wastewater Solids Did you know that nearly 50% of the solids in wastewater are organic matter? That's right—half of what’s swirling around in your treatment plant could potentially be turned into renewable energy or valuable fertilizers. But before we can start dreaming about turning […]
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 […]
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 […]
Long Term PFAS Solutions: Ensuring Safe Water for Future Generations Introduction Per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals," remain a pressing environmental and public health concern. Recent data indicates that an estimated 200 million Americans may be drinking water contaminated with PFAS at levels above the newly proposed EPA standards. As […]
PFAS Treatment System Maintenance: Ensuring Efficacy and Compliance Introduction Per- and polyfluoroalkyl substances (PFAS) have emerged as critical contaminants in water supplies, raising alarms among environmental professionals, municipal directors, and plant operators alike. With stringent regulations and public health implications leading to increased scrutiny, maintaining PFAS treatment systems has never been more crucial. The EPA […]
