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, 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 that 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 the installation of a high-capacity model to process the expected higher sludge volume associated with the recycling plant’s future expansion.
