هدف من البحث استخدام تقنية التخمر لإنتاج الغاز الحيوي من روث الأبقار. أنشئ المخمر وفق النموذج الهندي، و يتكون من حوض تخمير أسطواني ذي حجرتين بحجم /9.42 م3/ (ارتفاعه 3 م و قطره 2 م)، و خزان للغاز بحجم /6 م3/ و ارتفاع /1 م /، و أنبوب إدخال، و أنبوب خروج، و قد بينت النتائج مايلي: بلغ الإنتاج التراكمي من الغاز الحيوي خلال زمن التخمير و البالغ /30/ يوماً /48 م3/، و كان أعلى معدل لإنتاج الغاز في اليوم /13/، حيث بلغ /4.5 م3/، كما أصبحت رائحة المخلفات الموجودة في المزرعة ضعيفة، و تميزت المزرعة بعد استثمار المخمر بالنظافة و قلة الحشرات. باستخدام /1 م3/ من الغاز الحيوي الناتج تم تشغيل موقد متوسط الشعلة لمدة /2.5/ ساعة، و بذات الكمية تم تشغيل محرك احتراق داخلي ديزل بإعطائه /90%/ غاز حيوي و /10%/ وقود ديزل لمدة نصف ساعة. يعد 4/3 م3 من حجم المخمر كافياً للبقرة الواحدة، و التي ينتج عنها حوالي 12 كغ من الروث يومياً، و بذلك يمكن إنشاء المخمر المناسب حسب عدد الأبقار الموجودة في المزرعة أو المقرر تواجده في المزرعة.
The Research aimed to use the technology of the fermentation to produce the biogas from the cow manure. The digester has benn carried according to the Indian model. The digester consit of one cylinerical tank with 9.42m3 volume (height 3m, diameter 2m) and gastank with 6m3 (height 1m) and inlet pipe and outlet pipe. The study showed the following: The accumulated production of biogas was through the 30 days retention time 48m3. The heighest production was in the thirteenth day with 4.5m3. The farm became after the use of digester clean and with little insect and smell. With use 1m3 of biogas could we use one cooker for 2.5 hour and with the same quantity could we use one inner combustion diesel motor (90% biogas and 10% diesel) for half an hour. 3/4m3 from digester volume is enough for one cow with 12 kg manure daily. So we can design the suitable digester for any farm.

This study aimed to study the economic efficiency of producing
biogas from manure dairy cows, through cost and revenue account,
using some of economic indicators.
Poultry litter is an organic waste in Syria which can be a source of clean
energy if treated anaerobically. This research aimed to investigate the effect of
mechanical pretreatment of poultry litter in producing biogas and methane.
Experiments wer
e performed in units of fermentation laboratory on samples
ground spread over parts diameters 1 mm, 3 mm, and 10 mm at at 37°C
temperature, for a period of 42 days and compared with untreated samples
mechanically.
A reactor was designed to produce and rise the productivity of biogas
during anaerobic treatment of cattle dung.
It had a size of 32 cubic meters, constructed and installed. The material used
was a sheet of metal, the unit was put over the land.
The results indicated that the biogas production rate was 0.63 m3/m3, while
the daily average biogas production was 18.81 m3. The results also revealed that
the average percentage of methane content in biogas was 66.3%. The average
colorific value of produced gas was 451440 KJ/day.
The results also showed that, The digested sludge can be used as a good
fertilizer.
In this study, we review the possibility of production both ethanol and methanol from
OMW(OMW: Olive Mill Wastewater), fermented using pathogenic bacteria and isolated
marine bacteria. The results showed that when using Salmonella sp. bacteria, the
highest
values of methanol (5658.308 μg /l) appear at 7.5% concentration of the OMW, and the
higher concentration of ethanol (49.132 μg/l) at a concentration of 17.5% fermentation of
OMW. While Pseudomonas sp. produced the highest concentration of methanol (603.76μ
g/l) and ethanol (688.71μg /l) at 17.5% for OMW.
The results of this research showedthe ability of the bacteria isolated from sea water
in producing the above mentioned alcohols; for example the X3 bacteria displayed a direct
correlation between high concentrations of OMW (15 , 35 , 50)% and the high
concentrations of produced methanol (UL, 130.406μg/l, 1353.244μg/l ), apposite to
ethanol which was under the detection limits (under limited: UL).
The corrosion of biogas pipes and equipments damage as generators, boilers and coprocessors is one of
the most real important problems in Damascus wastewater treatment plant (at Adra region). These
problem caused high financial losses and costs , t
hat it required studying and solving. Biogas is the result
of an aerobic digestion process of sludge, it contains about 50-70% of methane as a main resource of
power, where the biogas considers free when it release spontaneity. Different analysis have been occurred
on the biogas to show its components, tests on the pipes material and analysis of sediment material inside
the pipes that caused by biogas.
