Abstract

The invention relates to a method and an apparatus for disinfecting sewage sludge. In the invention, sewage sludge is loaded from a silo into an open container (19), the open container is transferred away from the loading site, a granular calcium oxide (CaO) is dispensed into the sludge, a diluted peracetic acid solution is dispensed into the sludge and the sludge is mixed in the open container by means of at least four horizontal mixing screws (22, 23) for about two hours.
