Tag: Sludge Draw-off Valve

1. Introduction In the hydraulic architecture of municipal and industrial wastewater treatment plants, telescoping valves—frequently referred to as slip pipes, decant valves, or sludge draw-off valves—serve a critical, albeit mechanically straightforward, function. Unlike pressurized isolation valves used in distribution networks, telescoping valves operate primarily in open-channel or gravity-flow environments within clarifiers, sludge thickeners, settling tanks, […]
