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
Most bar screen and raking systems are expected to last 10 to 25 years before needing replacement. As components wear, and steel corrodes, wastewater treatment plants (WWTPs) have to choose between replacing parts and specifying a new system. However, Duperon customers have a third option that can save the money and downtime of buying a… Continue reading
