إن تحديد مواصفات الحمأة الناتجة عن عملية معالجة مياه الصرف الصحي له الدور الأساسي في معالجتها و التخلص منها. يهدف هذا البحث إلى دراسة مواصفات الحمأة الناتجة عن محطة مرج معيربان بدراسة عامل المقاومة النوعية للحمأة على الترشيح ( r' )، و لذلك قمنا بأخذ عينات حمأة من المحطة، و أجرينا عليها عدة تجارب مخبرية، و حصلنا على زمن تكثيف الحمأة، و رطوبتها، و تركيز المواد الصلبة فيها، و قمنا بحساب معامل المقاومة النوعية للحمأة على الترشيح عند قيم الرطوبة (97.5 , 95.5 , 94 , 92 , 91 , 88 ) %. أظهرت نتائج البحث انخفاض في قيمة عامل المقاومة النوعية للحمأة على الترشيح بانخفاض رطوبتها، و أن زمن تجفيف الحمأة يستغرق أسبوعين في محطة مرج معيربان.
The determination of sludge characteristics of wastewater treatment process has the primary role in the treatment and disposal. This research aims to determine the sludge characteristics by studying specific resistance factor of the sludge on the filtration at Merge Maarban station, so we took samples of sludge from the station and made several laboratory experiments and we got the time of intensify sludge, moisture and The concentration of the solid substances. we calculated specific resistance factor values of the sludge when the moisture values are ( 97.5 , 95.5 , 94 , 92 , 91 , 88 ) %. The research results showed a decrease in resistivity factor value of sludge on the filtration as its moisture become less and the sludge drying time takes tow weeks.

The study was conducted to determine the efficiency of the aerobic treatment of primary sludge resulting from sewage sedimentation and to determine the optimum residence time by measuring the indicators of total solids, chemical oxygen demand, organic content and dewatering ability of the sludge.
This study was performed at three plants for sewage treatment in Syrian coastal
villages: al-Hara, Murj-Muairban, and Hibbeat. Dry sludge samples were collected from
drying sludge basins monthly, during the period October 2011-September 2012. We
d
epended on different global ways to isolate the eggs from the sludge (flotation,
sedimentation, filtration through special sieves).
The microscopic study results of the sediment showed the presence of 5 different
species of the parasitic worm-eggs, belonged taxonomically to five different species of
parasitic worms, two species belonged to Nematoda: Ascaris lumbricoides and Trichuris
trichura, and three species belonged to Platyhelminthes: one species of them belonged to
Trematoda: Schistosoma mansoni, and the other two species belonged to cestodes: Taenia
saginata, and Diphyllobothrium latum.
The average number of worms eggs isolated from the dry sludge resulting from the
three studied sewage treatment plants (al-Hara, Murj-Muairban, and Hibbeat) recorded
relatively close values, the most number in the dry sludge resulting from the treatment
plant in Hibbeat with an average 97.16% eggs/50g, then al-Hara with an average
75.08egg/50g dry sludge. Also the results showed that the isolated eggs were more
diversed in Hibbeat treatment plant, this an indicator of the health status of the population
in the studied sites.
Study showed that the number and diversity of parasitic worm – eggs use more
observed in Summer and Autumn than in Winter and Spring.
The activated sludge is one of the most common methods of sewage treatment , which has been studied through to find the relation between sedimentation properties and the performance of aeration units. sedimentation experiments were applied on a highl
y- aerated activated sludge experimental treatment plant .Also, another experiments were applied on Marj Maerban treatment plant which is operated using the extended aeration method in order to find the Factors influencing the settling of activated sludge . These experiments were done using the Sludge volume index (SVI) ,the maximum velocity sedimentation rate (UMAX) and the time corresponding to the maximum velocity of sedimentation (TUMAX).In experimental treatment plant. We found that the sedimentation experimental parameters (Vo, n) are very sensitive and can be changed significantly with changing the values of suspended solids (MLSS) in the aeration tank. The mathematical relationships can be used to predict the value of (Vo, n) as well as designing and selecting the operating system of sludge without resorting to a conventional sedimentation tests . We also found in the extended aeration the maximum velocity sedimentation rate (UMAX) is the most important in settling process as we got some good correlation coefficients (R2) between UMAX and (TUMAX, MLSS, SVI) was at a temperature (20OC) were respectively (98, 96,98%), and when the temperature (17 OC) respectively (97,96,97%) which is almost the same values. We noticed that the sludge volume index (SVI) is closely associated with the settling parameters (UMAX, TUMAX) with the correlation coefficients were respectively (98,99%) on the temperature of (20OC) and (98,97%) on the temperature of (17OC) . Velocity sedimentation rate (UMAX) was the largest and deposition time (TUMAX) was smaller on the temperature of (20OC) Indicating an improved sedimentation with higher temperatures . Subsequently, temperature is an influential factor on deposition and It is necessary to be taken into account in the design and operation of activated sludge treatment plan.
In developing countries, including Syria solid waste sector contributes to the
emission of greenhouse gases, mainly methane, due to the lack of methods of integrated
management of solid waste in these countries.
The objective of this research is t
o study the feasibility and effectiveness of
mechanical biological treatment of municipal solid waste in a way to reduce methane gas
emissions compared to the way the indiscriminate dumping of municipal solid waste. In
order to reach this goal is the use of the formula contained in the guidelines of the
International Panel on Climate Change (IPCC) in account the emissions of methane from
municipal solid waste sector in the Syrian Tartous in the case of landfilling of municipal
solid waste generated by the province during the years from 2010 until 2015 in random
landfills. In order to compare the account is an assumption that the same amount of
municipal solid waste generated by the province during the years from 2010 to 2015 have
been treated in accordance with the mechanical biological treatment method. It was also
calculate the amount of methane emitted from municipal solid waste entering the
integrated waste treatment center in the Province of Tartous within one year from the
beginning of June 2014 until the end of May 2015, using mechanical biological treatment
method.
This study concluded that the mechanical biological treatment for municipal solid
waste significantly reduces the amount of methane emissions from solid waste sector
compared to the landfill, where the percentage of reduction in the emission of methane
93%.
Electric energy is very important for sustaining the good life on the planet's surface, especially since civilization has become associated with this type of energy. Solar photovoltaic (PV) is one of the most suitable applications for converting sunl
ight into electrical energy. The appropriate use of solar energy is an important topic for reducing dependence on fossil energy sources that are used to generate electricity, and thus reducing the emissions of greenhouse gases on the planet's surface. Globally, because of environmental conditions, other methods of generating energy being searched for that are less harmful than traditional methods, which rely on a large percentage of them on generating stations that run on fossil fuels. This research discusses electrical power generation using solar energy cells and the effect of these cells on the Syrian electrical grid so that a study of a solar energy farm project provides the data required when working on implementing such a project, and these data are voltage control, load flow, total harmonic distortion coefficient levels. To implement such a project, the model must be designed and we chose the ETAP program for that.
