| Microbiological investigation of sludge treated with quick lime |
| The aim of the investigation was to study the inactivation of selected bacteria and parasite ova in sludge treated with 5, 10 and 20% of CaO. The elimination rate of pathogens varied and depended on lime doses. When sludge was treated with 20% CaO all Ascaris eggs were destroyed after 6 hours, and, additionally, bacterial pathogens after 0.5-1 hour. The hygienization of sludge with 5 and 10% CaO was inefficient because only 6-9% of A.suum eggs were destroyed during the 24 hour period; most bacterial pathogens, however, were eliminated. Only sludge treated with 20% CaO and stored for 24 hours may be used for agricultural purposes |
