Dewatering of Mine Drainage Sludge - EPA

The most promising coal mine sludge dewatering technique appears to be vacuum filtration. Other methods such as sand bed filtration, pressure filtration and centrifugation may also be applicable. Recommendations are made as to the areas in coal mine drainage treat- ment and sludge densification that need further research.
