Disk Filter(Thickener)

A new generation of white water recovery and stock thickening equipment. The Disk filter (disk thickener)can save energy and water, reduce fiber loss, achieve the goal of protecting the environment and preventing pollution. It mainly applies to white water recovery during the process of papermaking and stock thickening during the process of pulping. High rate of fiber recovery during white water recovery, achieving water circulation, reducing water consumption, preventing white water pollution. High outlet consistency of 12-14% for stock thickening.It has passed assessment of result with national advanced standards.
a. White water recovery during the process of papermaking
b. Stock thickening during the process of pulping.
