Andritz
Efficient Sludge Management has become a challenge all over due to increasingly stringent land disposal regulations on one hand and steadily arising waste water quantities on the other hand. Andritz’ answer to these requirements are drying technologies, producing a valuable dried product which can be handled, treated, stored, disposed off and even utilized easily and safely. Frost & Sullivan’s 2004 Market Leadership award in the European Sludge treatment equipment market was presented to Andritz for its long-standing domination of the drying segment.
