ABSTRACT
Over the last few years, sludge from water treatment processes, especially those from urban waste water treatment plants, became a debate subject in the European Union. This reflects the increasing awareness of the fact that sludge quantities are constantly growing. If we take a look on the Romanian legislation we can see that sludge resulted from wastewater treatment processes are very strictly regulated but the sludge resulted from drinking water treatment processes are not subject for those laws. Because sludge from drinking water treatment is not subject to OM 344/2004, spreading it on land would mean using it without any regulations to control environmental effects. This paper aims to present the trends and technologies for processing, recovering and disposing the sludge produced in water treatment plants with concrete examples.

Keywords: Romanian legislation, sludge, water treatment plant, treatment process, dry substances.
