Introduction to Horizontal End Suction Pumps in Water & Wastewater In the complex hydraulic landscape of municipal and industrial water treatment, the horizontal end suction pump remains the ubiquitous workhorse. While vertical turbine pumps may dominate deep well applications and submersible pumps handle the depths of wet wells, the horizontal end suction (HES) configuration is […]

Introduction In the design of municipal water treatment plants and industrial wastewater facilities, the butterfly valve is often treated as a commodity item. This assumption—that “a valve is just a valve”—is a primary driver of unexpected operational expenditure (OPEX) and premature system failure. Engineers frequently encounter scenarios where a valve specified for general isolation fails […]

Solids Management in Wastewater Treatment: Strategies and Technologies Overview of Solids Management in Wastewater Treatment Did you know that nearly 80% of the solids generated in wastewater treatment plants end up in landfills? That's a staggering amount of waste that could be managed more effectively. Solids management is not just a regulatory requirement; it's a […]

Introduction Ion exchange (IX) remains one of the most versatile and critical unit processes in water treatment, yet it is frequently the source of significant operational expenditure (OPEX) overruns due to improper specification. Engineers often face a dichotomy: simple softening applications are treated as commodities, leading to premature vessel failure or inefficient salt usage, while […]

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 […]
