Decanter centrifuges play an important role in the removal of the water content from the industrial wastes and from the muds produced in the waste water facilities. Decrease in the volume and weight of the dried mud helps to decrease the disposal and transport costs seriously. When the high performance of the conventional equipments manufactured by the POLAT MACHINERY are combined with the innovative design of the S serial decanter centrifuges, this combination makes it possible to produce the driest mud for the lowest cost. With many technical revolutions, it provides energy savings reaching to 40% and retains the CO2 emission at the lowest level and keeps the lifecycle cost at minimum level. Dehydration of the high mud volumes requires high torques and effective control. S serial decanter centrifuges are designed to meet the requirements needed for the high torques and effective control at all capacities.
