Introduction One of the most persistent challenges facing municipal engineers today is the accurate monitoring of Combined Sewer Overflows (CSOs) and stormwater systems under regulatory consent decrees. The engineering challenge is multifaceted: equipment must survive in harsh, rag-prone environments, operate reliably during rapid hydraulic changes, and provide data accurate enough to satisfy environmental agencies. A […]
Membrane Bioreactor Technology: Advanced Solutions for Wastewater Treatment In an era where sustainable water management is more critical than ever, membrane bioreactor (MBR) technology stands out as a game-changer in wastewater treatment. This innovative approach combines biological treatment processes with advanced membrane filtration, offering superior effluent quality and efficient nutrient removal. In this post, we'll […]
Introduction In wastewater treatment plant (WWTP) design, the clarifier is the hydraulic control center of the process, but its efficiency is entirely dependent on the accuracy of the feedback loops controlling it. A common challenge engineers face is the disconnect between mechanical clarification systems and the instrumentation required to optimize them. While mechanical failure is […]
Introduction The secondary clarifier is often described as the most critical bottleneck in activated sludge systems, yet its performance is frequently limited by the quality of the data feeding the control loops. For municipal consulting engineers and plant directors, the “black box” nature of clarification—where settling zones and compression layers are hidden beneath the surface—presents […]
INTRODUCTION In municipal and industrial water treatment, the “set it and forget it” mentality regarding chemical feed systems is a primary driver of operational inefficiency and compliance violations. While metering pumps and storage tanks are the muscles of the system, the instrumentation—specifically flow meters and level transmitters—acts as the nervous system. A surprising industry statistic […]
Introduction Cavitation is the silent killer of hydraulic efficiency and mechanical integrity in water and wastewater systems. For municipal and industrial engineers, the challenge is rarely just about selecting a pump; it is about selecting the instrumentation loop that can survive, detect, and mitigate the conditions that lead to cavitation. When incipient cavitation creates two-phase […]
1. INTRODUCTION In the hierarchy of unit processes within municipal and industrial wastewater treatment facilities, solids conveyance systems often receive less design scrutiny than liquid stream biological processes. However, the mechanical transport of dewatered biosolids, screenings, and grit represents one of the most mechanically intensive and maintenance-critical operations in a treatment plant. The failure of […]
1. Introduction In the context of municipal and industrial water and wastewater treatment, aeration blowers represent the single most critical active component in the biological treatment process. They serve as the “lungs” of the plant, delivering the necessary oxygen to microorganisms within activated sludge basins, membrane bioreactors (MBR), and aerobic digesters. From an energy standpoint, […]
Introduction The anaerobic digester gallery is arguably the most complex and hazardous environment within a Water Resource Recovery Facility (WRRF). Engineers are tasked with balancing two volatile forces: the biological/hydraulic requirement to keep sludge moving and heated, and the thermodynamic requirement to safely contain and manage explosive methane gas. A single specification error in either […]
Modern Water Softening Technology for Municipal Applications In an age where water quality is more crucial than ever, municipalities are turning to modern water softening technology to tackle the challenges posed by hard water. This blog post will explore various innovative solutions, from traditional ion exchange systems to cutting-edge salt-free alternatives, that are transforming the […]
