Introduction Aeration systems consume approximately 50% to 70% of a typical activated sludge wastewater treatment plant’s total energy budget. Consequently, the selection of aeration hardware is one of the most consequential decisions a consulting engineer or plant director can make. A difference of merely 1-2% in Standard Oxygen Transfer Efficiency (SOTE) or a marginal increase […]
1. Introduction The Tallman Island Wastewater Treatment Plant (TIWWTP) stands as a critical component of the New York City Department of Environmental Protection (NYC DEP) wastewater infrastructure portfolio. Located on a 31-acre promontory in College Point, Queens, the facility provides essential sanitation services for approximately 400,000 residents in Northeast Queens. Originally commissioned in 1939, Tallman […]
Introduction In the realm of fluid dynamics and mechanical processing, the mixing unit is often the heartbeat of a treatment train. For decades, engineers have faced a binary choice when specifying heavy-duty agitation equipment for critical municipal and industrial infrastructure. A comparative analysis of SPX Lightnin vs Philadelphia Mixing for Mixers: Pros/Cons & Best-Fit Applications […]
1. Introduction In the modern landscape of municipal and industrial water and wastewater treatment, the electric valve actuator serves as the critical interface between the control room (SCADA) and the physical process. While the valve body itself—whether a gate, butterfly, plug, or ball valve—dictates the hydraulic characteristics of the system, the electric actuator determines the […]

Introduction Wisconsin’s wastewater infrastructure is defined by a unique combination of high-density urban treatment needs and significant industrial loading from the state’s robust food and paper processing sectors. The state operates under the regulatory oversight of the Wisconsin Department of Natural Resources (WDNR), which enforces some of the strictest phosphorus discharge limits in the United […]
Introduction One of the most persistent and costly inefficiencies in water and wastewater treatment plants is poor chemical dispersion. Inadequate mixing leads to chemical overuse, formation of disinfection byproducts, and unstable process control. When designing rapid mix, flash mix, or blending systems, engineers are often faced with a fundamental choice between two distinct technological philosophies: […]
Introduction Virginia’s wastewater infrastructure represents some of the most advanced treatment technology in the United States, driven largely by the stringent nutrient reduction mandates of the Chesapeake Bay Preservation Act. With a growing population of over 8.7 million and a geography ranging from the tidal coastal plains to the mountainous Blue Ridge, the state’s engineering […]
