Introduction One of the most persistent challenges in municipal and industrial water treatment design is the fragmentation of technology. A typical treatment plant is a complex assembly of headworks, biological processes, clarification, disinfection, and solids handling systems. When engineers treat these as isolated unit processes, the facility often suffers from integration failures, disparate control philosophies, […]

INTRODUCTION The selection of check valves in municipal water and wastewater treatment plants is often treated as an afterthought compared to the rigor applied to pump selection. However, the check valve is the primary defense against water hammer, reverse flow damage to rotating assemblies, and severe piping fatigue. When engineers evaluate Crane vs Henry Pratt […]

Introduction For municipal and industrial wastewater engineers, the management of solids—specifically the reduction of ragging, stringy materials, and debris—remains one of the costliest operational challenges. Unscheduled downtime due to clogged pumps or damaged downstream instrumentation costs utilities millions annually in labor and equipment replacement. When evaluating solids reduction technologies, engineers often face a critical fork […]

Introduction In the hierarchy of municipal and industrial fluid control, the ball valve occupies a critical position defined by its low head loss characteristics, tight shutoff capabilities, and versatility across a wide range of diameters. For consulting engineers, plant superintendents, and utility decision-makers, the selection of Original Equipment Manufacturers (OEMs) for ball valves is not […]
