Abstract EN

Health and environmental factors as well as operational difficulties are major challenges facing the development of an anaerobic digestion process.

Some of these problems relate to the use of sludge collected from primary and secondary clarifier units in wastewater treatment plants for laboratory purposes.

The present study addresses the preparation of sludge for laboratory purposes by using a mixture that consists of the digested sludge, which is less pathogenic, compared to the collected sludge from the primary or secondary clarifier, and food wastes.

The sludge has been tested experimentally for 19 and 32 days under mesophilic conditions.

The results show a steady methane production rate from the anaerobic digester which used sludge with a rate of 1.5 l/day and concentration around 60%, with comparatively low H2S gas content (10 ppm).

The methane produced from the digester that used only digested sludge decreases during the experimental period.
