Water Hammer Understanding and Mitigation Techniques

This white paper discusses the phenomenon of water hammer, which is a pressure surge caused by the sudden stopping or changing direction of fluid in piping systems. It outlines the harmful effects of water hammer, including equipment damage, noise and vibration, reduced efficiency, and safety risks. The document details various techniques employed by engineers to mitigate these effects, such as the installation of surge suppressors and the design of flexible piping systems. Additionally, it presents Proco Products' solutions, specifically their duckbill check valves, which are designed to prevent backflow and reduce the risk of water hammer. The paper includes a case study of the Jimmy Smith Wastewater Treatment Plant, which experienced significant water hammer issues and successfully resolved them by implementing Proco's check valves. The document emphasizes the importance of proper design and maintenance of piping systems to minimize risks associated with water hammer.
