Float Wash Fractionator
The Float Wash System is a modular designed static Micro Screen Fractioning device typically used for filtration separation for paper machine White Water. By directing spray through nozzles upward against individual dual layer mesh screens, fiber is rejected and flushed down into a common course fraction (reject) header. Fine (accept) fraction passing through the mesh screen, overflows into a fine fraction retention seal tank and sent back to the mills shower feed tank. The compact modular design allows for simple compartmentalized isolation to allow individual screen inspection and cleaning without interrupting the remaining process flow. This design also allows for future flow volume increase by adding additional bolt-on assemblies. The Float Wash System is controlled by a Dual PID loop feed pressure and vacuum controller.
