Anaerobic digestion is a well-known 'technique for wa.'ite management
which could have constituted health' ha=ard as well as environmental
pollution. To enhance the biogas production, Starter Digestate (SD) by
5% of digester l'olume (F2J and Agricultural Wastewater (A W) with SD
(F3) were pel/ormed on raw materials of Cattle Dung (CD), Poultry
Droppings (PD). Sugar beet Leaves (SL) and Water Hyacinth (WH)
compared with blank test (FI) (Fap water) under different fermentation
mixtures in order to study their effects on biogas and methane production,
total nitrogen and pH.
Results indicated that using agricultural wastewater and starter digestate
5% (F3) acheived the highest biogas production, methane percentage and
total nitrogen comparing with the other treatments. With respect to
fermentation mixtures, mixture of 50% SL + 50% WH (B) gave the
highest methane percentage (77%), while mixture of50% PD + 25 % SL
+ 25% WH (D) produced high concentration of N (5.3%) as a rich
fertili=er with an average biogas production (778 mUday) through
fermentation period of24 days.
