Abstract

Biological sludges stored for 4 months in a silo under oceanic climate, showed a limited maturation with a loss of dry solids and an increase of ammonia nitrogen availability. The die off rate of the fecal indicator organisms (except sulphate reducing clostridia) and Salmonella, was higher than the removal rate for enteroviruses and parasite eggs. A low viral contamination (20 UFP 1−1) remained whatever the season. If there was removal of ancylostoma eggs, storage had little effect on coccidium and amoeba cysts removal.
