The HI-Q® Fibresaver™ fiber filter provides efficient and economical recovery of good fiber from a filtrate stream. The HI-Q® Fibresaver capitalizes on advances in electron beam drilled perforated screenplates and in new rotor technologies. The HI-Q® Fibresaver is derived from the HI-Q® Fine Screen with all bearing assembly parts being interchangeable with corresponding models.
- Key Benefits
- high filtration efficiency
- stable of operation
- minimal maintenance
- low specific power consumption.
- continuous, remote, unattended operation.
- Applications
- Removal and recovery of good fiber from filtrate going to the chemical recovery system (weak black liquor).
- Recovery of good fiber from bleach plant washer filtrates.
- Operation
The Fibresaver(tm) Fiber Filter is designed for continuous, remote, unattended operation. - Liquor passes through the screenplate perforations (which can be as small as 0.1 mm [0.004 in.]) into the accepts compartment and is discharged through the accept connection. The remaining liquor, rich in recovered fiber, continues to flow downward and is discharged through the reject connection.
- The J Rotor evolution minimizes power consumption.
- Maintenance
- The screen rotor is mounted on a sturdy vertical shaft supported by self purging, grease lubricated, heavy duty bearings.
- To minimize spare parts inventory, the entire bearing housing (column assembly) is interchangeable with our corresponding HI-Q Fine Screen models.
- Shaft sealing is done with a double tandem mechanical seal with no fresh water entering the system.
