Water Quality Aspects of Coal Transportation by Slurry Pipeline

摘要

The research program was designed to: (1) identify and characterize water quality changes during movement of western coal by slurry pipeline; (2) determine feasibility for using impaired quality water (such as municipal industrial effluents) as slurry medium; and (3) determine treatment measures for restoring water quality of the slurry waste water if needed. Water quality parameters measured included alkalinity, BOD, COD, trace elements, dissolved solids, nitrate, sulfate, pH, silica, specific conductance, and total hardness.
