The authoritative resource for consulting engineers, utility managers, plant operators, and municipal decision-makers. 1. Introduction to Delaware’s Wastewater Infrastructure Delaware’s water and wastewater infrastructure serves a unique geographic landscape, supporting just over 1 million residents across its three counties—New Castle, Kent, and Sussex. Despite its small size, the state manages a highly diverse treatment portfolio, […]
Introduction to Biological Oxygen Demands One of the most persistent engineering challenges in wastewater treatment plant (WWTP) design is the “aeration paradox.” Biological processes require aeration systems capable of meeting the ultimate 20-year peak hourly organic load, but these same systems must operate efficiently under the severely reduced organic and hydraulic loads present during the […]
Introduction In municipal and industrial biological treatment facilities, aeration systems routinely account for 50% to 60% of total plant energy consumption. A poorly specified blower package directly translates to hundreds of thousands of dollars in wasted electrical expenditures over a standard 20-year lifecycle. Despite this immense operational expense, the evaluation and selection of the Top […]
When influent flows swing, permits tighten, and site footprints are constrained, sequencing batch reactors offer a compact, controllable alternative to continuous activated sludge. This guide translates SBR systems into actionable design rules, operational controls, troubleshooting workflows and retrofit strategies, with target ranges and decision criteria to compare performance against continuous basins and MBRs. Aimed at […]
Tighter permits and higher public scrutiny mean controlling nitrogen and phosphorus is a front-line operational issue for many utilities. This guide to nutrient removal wastewater gives municipal decision makers, plant designers, and operators straight answers on selecting, sizing, operating, and monitoring nitrogen and phosphorus control options, and when recovery makes sense. Expect engineering setpoints, performance […]
