title: Inactivation of indigenous viruses in raw sludge by air drying.
abstract: Air drying of raw sludge caused inactivation of indigenous viruses. A gradual loss of infectivity occurred with the loss of water until the solids content reached about 80%. A more rapid decline of viral infectivity occurred with further dewatering.
