A NEW PROCESS FOR SEPARATION OF LIGNIN FROM LIGNIN CONTAINING SOLUTION OBTAINED FROM PAPER AND PULP MILLS OF ANY OTHER SOURCE

摘要

The present invention relates to a novel process whereby lignin from paper and pulp mill streams, or from lignin solution obtained from any other source, can be precipitated by the use of combination of two or more additives,that results in 80-99% color removal, along with 80-95% COD reduction from the initial lignin containing stream.
