ExtremeDuty™: Vigorous Mixing of Anaerobic Digester Contents For nearly 30 years, WesTech has been supplying mechanical sludge mixers for wastewater treatment plants. The current sludge mixer has evolved over the years as a result of WesTech striving to meet and exceed our customers’ needs. WesTech ExtremeDuty™ Sludge Mixers provide vigorous mixing of digester contents to prevent stratification and improve the anaerobic digestion process. They reliably speed gas production while reducing foaming and scum accumulation. This rugged design was originally developed to reduce the high service costs of egg-shaped digester mixers. It has proven to be so reliable that the ExtremeDuty Sludge Mixer is now used for maximum efficiency and durability in all WesTech digester mixing applications. The stellar performance of the durable ExtremeDuty Sludge Mixer is proven in more than 700 installations, with an unprecedented full five-year warranty.
