Lagoon Treatment Systems: Natural Wastewater Processing Article Overview Article Type: Informational Primary Goal: Provide municipalities, design engineers, plant operators, and equipment manufacturers with a practical, technically rigorous guide to lagoon treatment system selection, design, operation, performance expectations, limitations, and upgrade strategies so they can evaluate whether a lagoon system is appropriate and how to design […]
Introduction In high-volume municipal flood control, stormwater management, and industrial water transport, the axial flow “propeller” pump is the workhorse of the hydraulic world. However, their unique specific speed characteristics and sensitivity to intake conditions make them prone to issues that differ significantly from standard centrifugal pumps. Engineers and operators frequently overlook the subtle precursors […]

INTRODUCTION One of the most persistent challenges in municipal and industrial fluid handling is not the pump itself, but the configuration of the installation. Engineers frequently encounter systems where high-quality rotating assemblies fail prematurely due to poor intake design, inaccessible valving, or structural resonance—issues directly tied to the physical installation method. Statistics from major utility […]
Introduction In municipal and industrial water treatment infrastructure, the reliability of auxiliary equipment often dictates the resilience of the entire process. While massive raw sewage lift pumps garner the majority of capital planning attention, the failure of miscellaneous pumps—seal water systems, polymer feed pumps, sampling units, and dry-pit sump pumps—frequently triggers permit violations or costly […]
Dissolved Air Flotation: Separating Solids from Wastewater Article Overview Article Type: Informational Primary Goal: Provide municipalities, design engineers, operators, and equipment manufacturers with a practical, technical reference for selecting, designing, operating, and troubleshooting dissolved air flotation systems to optimize solids separation, footprint, and lifecycle cost for municipal and industrial wastewater applications Who is the reader: […]
Introduction In municipal water and industrial wastewater treatment facilities, pressure instrumentation is the sensory nervous system of the process. Yet, a surprising number of process upsets, pump protection failures, and chemical dosing errors can be traced back to a single, often overlooked component: the diaphragm seal (or chemical seal). Engineers frequently treat these isolation devices […]
Introduction In municipal and industrial wastewater treatment, the precision of chemical dosing is directly linked to process compliance, yet the longevity of the dosing equipment is often compromised by material mismatching. A common point of failure in chemical feed systems is not the mechanical drive mechanism, but the degradation of wetted parts due to unforeseen […]
