    Assessment of Intestinal Parasites in the Effluent Slurry of Toilet-Linked Biogas Digesters
    (Addis Ababa, Ethiopia, 2006) Hailu, Tesfaye; Mekonnen, Yalemtsehay(PhD)
    Five toilet-linked biogas digesters working with in the range of ambient temperature were assessed to detennine the presence of intestinal parasites in the effiuent slurry considering the four seasons. These were in Addis Ababa (at Asko, Lidcta and BisrateGebriel), at Fitche and Awassa. Retention days were dctcnnined through recording the flow rate of influent slunies. Eggs of intestinal parasites of the influent and effluent slurry from the di gesters were identified by taking samples when the influent channeled into the digester at the mixing pit and effiueDt slurry away through the reservoir for each season.
