Keeping loose vegetation out of a waterway is a common purpose for nearly every trashrack. As vegetation accumulates on a screen, it can cause blinding and lead to head loss. In applications with heavy vegetation, large floating mats can be particularly problematic. There are a lot of trashrack designs that have capabilities to address vegetation,… Continue reading
Trashracks serve the simple but critical purpose of keeping large debris out of a water system. They are often placed in high-volume channels, drainage canals, pump stations, or flood control systems. Whether the goal is to pull water out of a residential area or supply water to a hydroelectric plant or a nuclear facility, it… Continue reading
Many wastewater treatment plants (WWTPs) design their screening with peak flow in mind. This means debris bypass or larger screen-opening sizes and slower scraper speeds, a compromise that results in suboptimal screening during normal flows. Unfortunately, letting more debris through the screen during normal flow can lead to costly problems, such as pump clogs and… Continue reading
