ExtremeDuty Sludge Mixers from WesTech Engineering provide vigorous mixing of digester contents to prevent stratification and improve the anaerobic process. They reliably speed gas production while reducing foaming and scum accumulation. This design was originally developed to reduce the high service costs of egg-shaped digester mixers. It has proven to be so reliable that the unit is now used for maximum efficiency and durability in all WesTech digester mixing applications. 801/265-1000; www.westech-inc.com.
