Advanced Odor Control Strategies for Wastewater Treatment Facilities Chemical Odor Control Techniques When it comes to odor control for wastewater, the stakes are high. A single whiff of that unmistakable scent can lead to complaints, lost business, and even fines. In fact, studies show that nearly 60% of residents near wastewater facilities report issues related […]
1. Introduction In the hierarchy of fluid handling equipment within municipal and industrial sectors, dewatering pumps occupy a unique and critical position. Unlike permanently installed process pumps designed for steady-state operations within a treatment plant, dewatering pumps are often tasked with transient, emergency, or variable-duty cycles in uncontrolled environments. For the consulting engineer and plant […]
Introduction In the realm of municipal and industrial wastewater management, the failure of a grinder pump due to ragging or jamming is rarely a minor inconvenience—it is a distinct operational hazard that leads to Sanitary Sewer Overflows (SSOs), costly emergency call-outs, and accelerated equipment degradation. With the increasing prevalence of “non-flushable” wipes and high-tensile synthetic […]
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 […]
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 […]
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 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 One of the most persistent inefficiencies in modern wastewater treatment plants is the misapplication of mixing energy. While aeration systems typically consume the lion’s share of plant power, submersible mixers often operate continuously in anoxic zones, sludge holding tanks, and equalization basins, accumulating massive lifecycle costs. A surprising industry statistic suggests that up to […]
Introduction For municipal engineers and utility directors, the proliferation of “flushable” wipes and increasing solids loading in wastewater streams has transformed the specification of pump stations. The days of standard solids-handling pumps working universally are over; difficult terrain and high-head requirements often necessitate Low Pressure Sewer (LPS) systems driven by robust grinder pumps. However, selecting […]
