Introduction Peristaltic pumps (often referred to as hose pumps or tube pumps) are frequently selected for their ability to handle aggressive chemicals, viscous sludge, and shear-sensitive fluids in water and wastewater treatment. However, despite their mechanically simple design—typically involving a rotor compressing a hose—they present a unique set of operational challenges. A surprising industry statistic […]
Introduction In the realm of municipal wastewater treatment and industrial slurry handling, the double disc pump has carved out a niche as a robust solution for difficult fluids containing solids, rags, and grit. However, a surprising number of these installations fail prematurely, not due to mechanical inadequacy, but because of improper Variable Frequency Drive (VFD) […]
Ion Exchange Water Softening: How to Remove Hard Water Minerals Article Overview Article Type: How-To Guide Primary Goal: Give municipal and industrial wastewater professionals a detailed, engineer-grade guide to design, specify, operate, and troubleshoot ion exchange water softening systems that remove calcium and magnesium, including resin selection, regeneration chemistry, brine management, monitoring and a worked […]
INTRODUCTION One of the most persistent and costly misconceptions in municipal and industrial water treatment is viewing a wet well merely as a concrete holding tank. In reality, the wet well is a complex hydraulic structure that dictates the reliability of the pumping equipment. A startling number of premature pump failures—often attributed to “defective manufacturing”—are […]
INTRODUCTION The integration of Variable Frequency Drives (VFDs) with non-clog wastewater pumps has become the standard for modern municipal lift stations and treatment plants. While VFDs offer significant benefits regarding energy efficiency, flow matching, and reduced mechanical stress during startup, they introduce complex thermal challenges that are often underestimated during the design phase. A critical […]
Introduction One of the most insidious threats to the longevity of large-scale pumping systems is the phenomenon of air entrainment caused by intake vortices. For municipal and industrial engineers, the challenge is compounded when geotechnical constraints force the use of deep, circular containment structures. Diaphragm Wet Well Design and Minimum Submergence to Prevent Vortexing is […]

Introduction Chemical dosing accuracy is the silent guardian of water quality compliance and the hidden driver of operational expenditure. In municipal and industrial treatment plants, the failure to properly understand hydraulic behavior results in millions of dollars lost annually to chemical waste, premature equipment failure, and process instability. A surprising industry statistic suggests that over […]
