Location: Laurel, Anne Arundel County, Maryland | Operating Authority: Anne Arundel County Department of Public Works (DPW) 1. Introduction The Parkway Wastewater Treatment Plant (WWTP) is a critical infrastructure asset within the Anne Arundel County Department of Public Works (DPW) system, serving the rapidly growing western portion of the county. Commissioned originally in the 1980s […]
INTRODUCTION In the realm of anaerobic digestion and cogeneration, the protection of downstream assets—whether internal combustion engines (ICE), boilers, or renewable natural gas (RNG) membranes—is paramount. Engineers often face a critical disconnect: the anaerobic digester produces valuable fuel, but that fuel is laden with hydrogen sulfide (H2S), siloxanes, and moisture that can destroy capital equipment […]

Introduction For municipal and industrial treatment plant engineers, solids handling frequently represents the most volatile component of operational expenditure (OPEX). While the liquid train often receives the bulk of design attention, the “tail of the plant”—sludge thickening, dewatering, and disposal—accounts for approximately 40% to 50% of total treatment costs. When evaluating the Top 10 Sludge […]
Introduction In the modern municipal water and wastewater landscape, the System Integrator (SI) occupies a critical role that transcends simple equipment supply. Unlike pump manufacturers or valve suppliers who provide discrete mechanical assets, the SI is responsible for the facility’s central nervous system—the Supervisory Control and Data Acquisition (SCADA) system, Programmable Logic Controllers (PLCs), Human […]
The authoritative technical resource for the Allegheny County Sanitary Authority regional treatment facility. FACILITY BASIC INFORMATION Plant Name: Allegheny County Sanitary Authority (ALCOSAN) Wastewater Treatment Plant Location: 3300 Preble Avenue, Pittsburgh, Allegheny County, Pennsylvania Operating Authority: Allegheny County Sanitary Authority (ALCOSAN) Design Capacity: 250 MGD (Average Daily), expanding to 480 MGD (Wet Weather) Current Average […]
Facility Status: Currently undergoing a massive multi-year expansion as part of the Clean Water Plan to increase wet weather treatment capacity from 250 MGD to 600 MGD. FACILITY BASIC INFORMATION Plant Name Allegheny County Sanitary Authority (ALCOSAN) Wastewater Treatment Plant (often referred to as Woods Run) Location 3300 Preble Avenue, Pittsburgh, Allegheny County, PA 15233 […]
Introduction The pressure to intensify nutrient removal within existing wastewater treatment plant footprints has never been higher. For municipal and industrial engineers, the Moving Bed Biofilm Reactor (MBBR) and Integrated Fixed-Film Activated Sludge (IFAS) processes represent a critical solution to this density problem. However, a staggering number of retrofit projects face operational bottlenecks not because […]
