Belt Press vs Centrifuge: Choosing the Best Sludge Dewatering Solution When choosing how to cut sludge volumes and disposal costs, the belt press vs centrifuge sludge dewatering decision is one wastewater manager faces every day. This post compares belt press dewatering and centrifuge dewatering on performance, energy and operational costs, maintenance and footprint, and environmental […]
Introduction to Water Treatment Instrumentation & Controls: SCADA Sensors & Automation One of the most frequent and costly failures in modern water infrastructure is not structural or mechanicalβit is a failure of visibility. When an aeration blower consumes 40% more energy than required because a dissolved oxygen sensor has drifted, or when a remote lift […]
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 […]
Introduction: The Shift to Ultraviolet Disinfection One of the most persistent challenges municipal and industrial wastewater engineers face is balancing stringent disinfection requirements with the environmental and safety risks associated with chemical treatment. For decades, chlorine contact basins were the default standard. However, the regulatory tightening around disinfection byproducts (DBPs), the stringent limits on total […]
This case study looks inside detroit water and sewerage operations to show how a large urban utility coordinates treatment, distribution, and financing at scale. We unpack the governance split with the Great Lakes Water Authority, the treatment train and SCADA strategies used to protect drinking water quality, and collection system practices for CSO control and […]
INTRODUCTION In municipal water distribution, wastewater collection, and industrial treatment processes, fluid containment is paramount. Yet, when commissioning new pipelines or upgrading pump stations, engineers and operators frequently encounter unexpected hydrostatic test failures or premature fugitive emissions. When analyzing these failures, experts routinely point to Valves – Construction Service Installation Mistakes That Cause Leaks as […]
Detroit water and sewer present a live, technical example of how aging pipes, combined sewers, and fragmented governance create chronic operational and financial risk. This case study synthesizes Detroit-specific diagnostics, the governance split with the Great Lakes Water Authority, funding pathways, and the technical interventions deployed to date. Expect concrete metrics, procurement and financing guidance, […]
Clark County water reclamation serves as a practical blueprint for municipalities facing stricter effluent limits, aging infrastructure, and tight budgets by tracing permitting strategy, technology choices, phased construction and operational handover. This case study delivers concrete timelines, commissioning and operator training checklists, vendor trade offs, and measurable KPIs practitioners can adapt for medium to large […]
The halo 5 water system is a UV-based treatment platform many utilities are evaluating for potable, reuse, and tertiary disinfection applications. This article delivers a technical breakdown of its architecture, hydraulics, lamp and control characteristics, and how delivered UV dose performs under representative water qualities, with head-to-head context against TrojanUV, Xylem Wedeco, and Evoqua. For […]
Effluents from municipal and industrial sources drive most operational headaches and permit risk at wastewater plants. This how-to guide provides a practical, technically detailed roadmap to design and operate effluent monitoring programs, select pretreatment and treatment strategies, and improve discharge quality while managing CAPEX, OPEX, and regulatory exposure. Expect clear decision criteria, sampling and QAQC […]
