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 […]

Introduction The safety and structural integrity of anaerobic digesters rely entirely on the precise management of internal pressures. For decades, the specification of gas safety equipment has largely been a binary choice in the North American market. Engineers evaluating Varec Biogas (Ovivo) vs Shand & Jurs for Digestion applications are navigating a landscape defined by […]
Introduction to Ozone System Engineering Ozone generation is one of the most chemically potent yet operationally complex technologies in the water treatment arsenal. Unlike UV or chlorination, ozone is generated on-site, requiring a sophisticated integration of power supply, gas preparation, cooling thermodynamics, and mass transfer mechanics. For municipal and industrial engineers, the challenge is rarely […]
