VERFAHREN ZUM ANAEROBEN ABBAU VON CALCIUMIONENHALTIGEN, ALKALISCHEN SCHWEMM- UND WASCHWAESSERN

摘要

1. Process for the anaerobic digestion of rinse and wash waters and decanted sludge transport waters containing calcium ions, particularly from the process of sugar production, in which the waters are treated in one or more stages in a methane reactor with formation of methane and carbon dioxide, characterized in that calcium ions are removed by precipitation as carbonate before the anaerobic decomposition.
