- Sludge Mixer


WesTech ExtremeDuty™ Sludge Mixers 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 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 proved in hundreds of installations worldwide. WesTech backs up this performance with an available unprecedented five year warranty that covers crane fees, freight, parts and labor in the unlikely event of a failure.
