Abstract
This paper is focusing on the first Romanian application of High Density Sludge (HDS) technology on a pilot scale for acid mine water treatment. The pilot HDS treatment plant (Geco variant) had a modular structure, very flexible in operation, able to operate in Low Density Sludge (LDS) and HDS systems, with three reactors, one flocculation tank and one settling tank. The main advantages of HDS technology were the lower amount of Ca(OH)2 (10% lower), lower volume of the sludge and the higher content of dry substance (15%) in the sludge.
