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 […]
Stormwater Treatment Systems: Managing Runoff Effectively Article Overview Article Type: Informational Primary Goal: Provide municipal engineers, wastewater operators, plant design engineers, and equipment manufacturers with a comprehensive, technically rigorous guide to selecting, designing, operating, and evaluating stormwater treatment systems so they can meet regulatory requirements, reduce pollutant loads, and improve resilience to changing rainfall patterns. […]
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 […]
Greywater Recycling: Sustainable Water Reuse Solutions Article Overview Article Type: Informational Primary Goal: Provide municipalities, engineers, wastewater plant designers, operators, and manufacturers with a technically rigorous, actionable guide to planning, selecting, designing, operating, and justifying greywater recycling systems for nonpotable reuse at municipal and large-building scale Who is the reader: Municipal water managers and decision […]
Introduction In municipal wastewater treatment and industrial sludge handling, the premature failure of progressive cavity (PC) pump stators remains one of the most persistent and costly maintenance burdens. Engineers frequently specify robust hydraulic conditions, yet the interface between the pump mechanics and the electrical control system is often where reliability disintegrates. A startling volume of […]
Biosolids Management: Best Practices for Treatment Plants Article Overview Article Type: How-To Guide Primary Goal: Provide treatment plant operators, engineers, and municipal decision makers with a practical, technically detailed roadmap for designing, operating, monitoring, and financing biosolids management systems that meet regulatory requirements, control risk, and maximize resource recovery. Who is the reader: Municipal wastewater […]
Introduction to Intake Hydraulics For municipal and industrial engineers, the physical geometry of a pump station is often treated as secondary to the selection of the pump itself. However, industry data suggests that nearly 30% of premature pump failures—manifesting as vibration, cavitation damage, and bearing wear—are directly attributable to poor intake conditions rather than mechanical […]
Coagulation and Flocculation: Essential Steps in Water Purification Article Overview Article Type: Informational Primary Goal: Provide municipalities, water and wastewater engineers, plant operators, and equipment manufacturers with a technically detailed, practice-oriented guide to coagulation and flocculation in water treatment that supports design decisions, operator troubleshooting, chemical selection, pilot testing, and online process control. Who is […]
Introduction One of the most persistent challenges in water and wastewater design is the “specification inertia” that dictates instrumentation choices. Engineers often replicate previous specifications without re-evaluating whether the technology has evolved or if the application demands have shifted. A staggering number of process upsets—estimates suggest up to 40% of minor deviations—can be traced back […]
