Title: Control of blackwater in coal preparation plant recycle and discharge. Open file report Oct 79-Sep 82 (final)

Control of blackwater in coal preparation plant recycle and discharge. Open file report Oct 79-Sep 82 (final) Water recycle is an important part of the coal preparation process. This study was directed toward (1) a survey of current practice and an evaluation of both the solid and liquid components of blackwater, (2) an experimental study of blackwater flocculation, and (3) a fundamental analysis of the flocculation process. More fundamental studies were made that clearly indicate the need for controlled mixing of polymer into the suspension to be flocculated and the need to evaluate more closely the structure of the flocs formed during the process.
