Ecological stretch film factory in Poland
Background
This recycling plant, where plastic films for agricultural and industrial use are produced, dewaters a very fibrous sludge. This type of sludge contains up to 5 cm long plastic pieces which is making this sludge problematic to dewater. The installed unit of VOLUTE DUO™ RVP-501 dewaters this highly fibrous sludge without any problems thanks to its patented double-cutting movement of the rings. The former single screw multi-disc screw press blocked after a few minutes’ operation.
Installation details
It was the customer´s wish to minimize the sludge volume as much as possible. Considering the unstable properties, of the sludge, the customer was very satisfied we can provide them with a solution that will smoothly dewater this tricky sludge. The twin screws dewatering press is the right solution for a highly fibrous sludge namely for its double-cutting moving rings movement which eliminates the risk of blockage to a minimum. The customer decided for an installation of a high-capacity model in order to process the expected higher sludge volume associated with the recycling plant’s future expansion.
