METHOD AND APPARATUS FOR REMOVING IMPURITIES IN REJECTS FROM SEQUENTIAL FILTERS USING SEPARATE TREATMENT UNITS

摘要

The disclosed method and apparatus involves the use of sequential filters for the purification of liquid. The sequential filters may each produce rejects that can be processed separately in their respective treatment apparatus, which can be fine-tuned to the specific reject that it treats. Alternatively, the first reject may be treated while the second reject may not be treated. The rejects (whether treated or not) may be combined into a combined flow and then be recycled in the sequential filters.
