--- title: Volute™ Thickener Brochure Download description: "A Volute Press Adapted for the Tough-to-handle Sludges\nFor more challenging applications, the Volute Duo™ Screw Press offers enhanced performance. Featuring twin counter-rotating screws within a single drum, this advanced system breaks up and processes difficult sludges—fibrous, inorganic, or oily—that other presses can’t handle. With the same energy efficiency and low-maintenance benefits as the original Volute™, the Duo excels in handling high-demand environments without compromising performance.\n\nThe Volute Duo™ Screw Press is versatile across sludge dewatering applications, excelling in conditions that cause clogging or blinding in traditional screw press designs. Key applications include:\n\nDewatering WTP sludge (alum, ferric and lime sludges)\nManaging sludge in pulp and paper processes\nProcessing raw manure in agricultural settings\nSupporting dredging and land remediation projects\nHandling raw primary sludge efficiently\nDewatering any fibrous or gritty/inorganic sludges" --- [![logo](https://blog.watertecnik.com/hs-fs/hubfs/logo.png?width=133&height=75&name=logo.png "logo")](https://watertecnik.com) BROCHURE DOWNLOAD # WATER TECNIK VOLUTE DUO™ SCREW PRESS     ## What's Inside?

Facing challenges with our outdated system, the trial of the containerised disc screw press system exceeded expectations, leading us to extend the rental and eventually opt for a fully customised solution. It has resulted in substantial cost savings for us....We now have a system that doesn’t cause us problems on a daily basis, and we would highly recommend Water Tecnik for any company looking at effluent treatment or sludge management systems"* Colin Bell,  Group Engineering Manager, Linergy ![Linergy-1](https://blog.watertecnik.com/hubfs/Linergy-1.png "Linergy-1")
