Rothensee WTE Plant

KMT assumes overall responsibility for the plant equipment and process technology of the sewage sludge incineration unit.

The plant is to combust approx. 55,000 t/year of dewatered municipal sewage sludge by means of KMT`s tried and tested fluidized-bed technology.

The generated saturated steam (11 bar(a), 184 °C) is used for predrying the sewage sludge. Owing to the combination with the WTE plant`s steam system, excess steam can be passed on or low-pressure steam may be obtained.

Since the sewage sludge incineration unit is equipped with its own dedusting system, the requirement to recover phosphorous from sewage sludge/ash is met. Following the separation of ash, the flue gas and the vapours from predrying are then introduced into the incinerator of the WTE plant. The flue gas mixture formed is treated in the WTE plant`s flue gas cleaning system.

The entire plant is to be built within 32 months.
