Introduction Missouri sits at the confluence of the nation’s two largest rivers—the Mississippi and the Missouri—making water quality management a critical priority for the state. The wastewater infrastructure landscape in Missouri is characterized by a dichotomy between massive metropolitan districts in St. Louis and Kansas City and a vast network of smaller municipal and rural […]

1. Introduction Maryland’s wastewater infrastructure is defined by a single, overriding geographical feature: the Chesapeake Bay. As the largest estuary in the United States, the Bay dictates the regulatory and technological landscape for the state’s water environment. Maryland is home to approximately 320 public wastewater treatment plants (WWTPs) that treat over 650 million gallons of […]

1. Introduction North Carolina stands at a critical juncture in water infrastructure management. With one of the fastest-growing populations in the United States—driven by the rapid expansion of the Charlotte metro area and the Research Triangle (Raleigh-Durham)—the state’s wastewater treatment capacity is under significant pressure. The North Carolina Department of Environmental Quality (NC DEQ) oversees […]

Introduction Pennsylvania’s wastewater infrastructure represents one of the most complex and historic networks in the United States. With a unique topography that spans the Delaware, Susquehanna, and Ohio River basins, the Commonwealth manages a vast array of treatment facilities ranging from massive metropolitan plants in Philadelphia and Pittsburgh to critical rural lagoons. Currently, Pennsylvania faces […]

Introduction: The State of New Jersey’s Water Infrastructure New Jersey represents one of the most complex and dense water infrastructure environments in the United States. As the most densely populated state in the nation, New Jersey’s wastewater sector manages a massive hydraulic load through a network of approximately 260 dedicated wastewater treatment plants (WWTPs). The […]

Introduction In the municipal and industrial water treatment sector, the “control valve” specification section is often where operational efficiency is either secured or compromised for decades. Engineers frequently encounter a critical decision point when reviewing valve submittals or writing proprietary specifications: the choice between two industry heavyweights. This article provides a technical deep-dive into Bray […]

1. Introduction In municipal and industrial wastewater treatment, the management of odors is not merely an aesthetic concern; it is a critical operational parameter that impacts regulatory compliance, community relations, facility safety, and infrastructure longevity. Odor Control Systems (OCS) represent the primary defense against the release of nuisance compounds—principally hydrogen sulfide (H2S), mercaptans, ammonia, and […]

Introduction Ultraviolet (UV) disinfection has transitioned from an “alternative” technology to the industry standard for pathogen inactivation in municipal water and wastewater treatment. However, a critical disconnect remains in the engineering community: the assumption that UV systems are static, “plug-and-play” appliances. In reality, an improperly specified UV system can become the plant’s largest energy consumer […]

Introduction In municipal and industrial pumping systems, the selection of check valve technology is the primary defense against destructive hydraulic transients (water hammer) and reverse flow damage. Engineers are frequently faced with a divergent choice when specifying pump discharge control: specifying an active, electrically or pneumatically actuated solution (often synonymous with Rotork actuation on a […]

Aqua Aerobic Systems: Innovative Solutions for Wastewater Treatment Mechanisms of Aqua Aerobic Systems Aqua aerobic systems are best suited for municipalities and industries that require efficient and effective wastewater treatment solutions with a focus on biological processes. These systems leverage aerobic digestion to break down organic matter, making them particularly advantageous in settings where space […]
