The Sludge Treatment Unit (STU) is designed for treating heavier slop waste such as sludge, water saturated mud etc. The separation technology includes an emulsion breaker injection system in combination with a decanter centrifuge with high slenderness ratio.

The unit is perfectly equipped to separate the solids from the water. The effluent water is suited for water treatment with the Compact Treatment Unit (CTU).
