Hygienization of sewage sludge with burned and hydrated lime
Sewage sludge was treated with CaO or Ca(OH)(2) (doses up to 350 g/kg of dry mass) for 96 h to eliminate Salmonella enteritidis bacteria. Full hygienization of the sludge was achieved after 1 h when CaO doses 250 g/kg or Ca(OH)(2) doses 350 g/kg were used.
