Introduction In municipal water distribution and industrial fluid handling, the “valve selection paradox” is a frequent challenge for consulting engineers: the most expensive valve upfront is often the cheapest over 20 years, yet the wrong hydraulic application can destroy even the highest-quality equipment in weeks. A surprising statistic from hydraulic efficiency studies suggests that up […]
Introduction In municipal and industrial hydraulic systems, the management of high pressure differentials presents a distinct physical challenge: cavitation. When water accelerates through a valve restriction to the point where the static pressure drops below the fluid’s vapor pressure, vapor bubbles form. As the fluid recovers pressure downstream, these bubbles collapse with violent force, generating […]
Introduction In the landscape of municipal and industrial water and wastewater treatment, the dry pit pump configuration remains a cornerstone of reliability, maintainability, and hydraulic versatility. Unlike submersible installations where the pump and motor are submerged in the process fluid, dry pit installations separate the fluid handling equipment from the wet well. The pump is […]
Introduction The sudden urgency surrounding PFAS/PFOA compliance, combined with the perennial need for taste, odor, and organics removal, has placed Granular Activated Carbon (GAC) technology at the forefront of utility capital planning. For many consulting engineers and plant directors, the challenge is no longer just selecting a media type, but specifying the mechanical vessel systems […]
Introduction to Flow Control Selection In the complex landscape of municipal water and wastewater treatment design, the “Bill of Materials” (BOM) is often the battleground where reliability meets budget. One of the frequent evaluation points for mechanical engineers and plant superintendents is the selection of piping specialties and isolation devices. When analyzing Proco vs Bray […]
Introduction In municipal and industrial water and wastewater treatment infrastructure, the integrity of containment vessels and the reliability of protective covers are foundational to process safety, regulatory compliance, and environmental stewardship. Tanks and covers serve a dual purpose: they facilitate the secure storage of hazardous chemicals and process fluids while mitigating environmental risks such as […]
1. Introduction Mixing equipment serves as the kinetic heart of municipal and industrial water and wastewater treatment facilities. Unlike passive components such as piping or static storage, mixers are dynamic machines responsible for facilitating chemical reactions, maintaining solids suspension, blending disparate fluid streams, and optimizing heat transfer. In the context of consulting engineering and plant […]
Introduction In the municipal water and wastewater sector, the electric actuator is often the single most critical interface between the control room (SCADA) and the physical process. Yet, despite their importance, actuators are frequently treated as commodity items or last-minute additions to valve specifications. This oversight often leads to a staggering statistic: industry analysis suggests […]
INTRODUCTION One of the most persistent challenges in municipal water distribution design is the control of storage tank levels—specifically, balancing the simplicity of mechanical hydraulic valves with the data-rich requirements of modern SCADA systems. For decades, the industry standard was the pilot-operated hydraulic globe valve. However, a significant shift is occurring toward electrically actuated quarter-turn […]
1. Introduction In the context of municipal and industrial water and wastewater treatment, the term “sleeve valve” primarily refers to valves utilizing a flexible elastomeric sleeve as the flow control element. While nomenclature varies—often overlapping with pinch valves or specific energy-dissipating inline valves—the fundamental engineering principle remains consistent: a resilient, tubular sleeve isolates the operating […]
