Folded Thickener

Working Principles

Parason Folded Thickner in compression to normal Thickeners provides a considerable larger filtration area. This can translate into smaller space requirement or higher capacity for specific floor space. The wire clothing is divided into sectors so that each section can be replaced without removing the drum/cylinder .

The stock suspension fed into cylinder through an inlet which evenly distributes the stock across the width of the thickener. The water passes through the wire mesh and the fiber mat is formed on the surface of the cylinder. Between the stock level in the vat and the surface of the drain water inside the cylinder, a hydrostatic pressure difference (∆h) is produced, which provides continuous filtration. The surface of the wire cloth cleaned by shower.

As Thickener for:
– Recycle Fiber, Chemical and Mechanical pulp
– Eflluent Sludge
– Broke
– Chemical Industry

As Washer for:
– Deinked Pulp
– Removal of Fillers and Fines from Recycled Fiber Pulp

The following relationships are applicable
Low freeness – High throughput capacity
High freeness – Low throughput capacity
High Feed Consistency – High throughput capacity
Low Feed Consistency – Low throughput capacity
