1. Introduction In municipal and industrial wastewater treatment, the management of residual solids—commonly referred to as sludge handling—represents one of the most complex and cost-intensive portions of the plant lifecycle. While the liquid treatment train often garners the primary focus regarding effluent compliance, the solids handling train dictates operational efficiency, disposal costs, and often the […]

Introduction Aeration systems consume approximately 50% to 70% of the total energy usage in a typical biological wastewater treatment plant. For consulting engineers and plant directors, the selection of aeration equipment is not merely a component choice; it is the single largest determinant of the facility’s 20-year lifecycle cost profile. A common friction point in […]

1. Introduction In the architecture of modern municipal and industrial water and wastewater treatment infrastructure, instrumentation serves as the central nervous system. While pumps, blowers, and valves perform the physical work of moving and treating fluids, it is the instrumentation—flow meters, level sensors, pressure transmitters, and analytical probes—that provides the data necessary to control these […]
Introduction In the modern era of wastewater infrastructure, the shift toward submersible pumping technology has been substantial. However, a significant percentage of municipal lift stations and treatment plants rely on the durability and accessibility of conventional dry pit pumps. Engineers frequently overlook the long-term operational benefits of separating the driver from the hydraulic fluid, particularly […]

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 […]
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 […]
