ABSTRACT:
A method for the treatment and disposal of sewage sludges containing chlorides (NaCl) as from infiltrating salt water, which involves heat treatment capable of producing readily disposable sludges, due to the resulting destruction of pathogenic organisms and improved filtrability of the sludge, featuring the washing displacement of NaCl from the sludge preceding the heat treatment operation, for protection of the sludge heating equipment.
