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 UR - http://nile.enal.sci.eg/EALE/2017/MJAE/3417/2/1103.pdf ER -
