Gar-Dur® UHMW applications for Wastewater Treatment Plant equipment. Primary and Secondary Sedimentation tanks, chain and flight systems.

Garland Manufacturing offers a complete line of non-metallic, abrasion resistant material and parts for wastewater treatment plant equipment, including sedimentation and clarifier tanks. In primary and secondary WWTP processing applications, UHMW is the best choice for sedimentation and clarifier tank components. No other material can match the benefits and long service life in high abrasion and high impact applications. For high grit applications, Garland Manufacturing offers our GarDur brand UHMW in both virgin grade UHMW, as well as UHMW RG, a reprocessed grade of UHMW Polyethylene.
