Mechanical Sludge Treatment

Efficient removal of solids and rags from imported municipal sludge prior to thickening or dewatering.
 

Sludge screening is used to remove coarse material, solids and rags and increases the operational reliability of subsequent sludge treatment.

With mechanical sludge thickening processes, the volume of conditioned thin sludge can be significantly reduced quickly and efficiently with a small footprint. The resulting concentrated thick sludge still remains free-flowing and is thus ideally prepared for the further treatment stages of stabilisation and dewatering.

Through high shear and pressure, sludge dewatering helps to achieve a dryer cake for transportation and storage. The degree of dewatering of the sludge has a significant influence on the costs of further sludge treatment steps such as transport, disposal and recycling.
