Practical selection notes
How filtration performance influences recausticizing stability, lime mud handling and liquor quality.
Role in the recovery cycle
White liquor filtration separates lime mud from the regenerated cooking liquor before it returns to the digester area. Stable filtration supports liquor quality, mud handling and the overall recausticizing balance.
- Poor clarity can increase downstream operating issues.
- Unstable mud discharge can create handling and washing problems.
- Filter selection should be coordinated with causticizing and lime mud washing equipment.
What buyers should compare
When comparing suppliers, buyers should look beyond the equipment name. The useful comparison is whether the proposed filter matches the mill's slurry properties, process layout and maintenance practice.
- Filtration area and process sequence.
- Material selection for liquor contact parts.
- Access, washing, discharge and control arrangements.
Upgrade considerations
For an existing kraft pulp mill, the best solution may be a replacement, a capacity adjustment or a supporting equipment change. Existing drawings and operating pain points are important for a realistic proposal.
Next step for buyers
Prepare your process data, production capacity, existing equipment information and project drawings. Anqiu Ocean Machinery can then discuss a suitable equipment configuration for quotation.
