In this study, a simulation of the MTR-22MW reactor and a study
of standard and mixed fuel combustion using the Codes GETERA
and MCNP5.
The Results of the simulation showed that the operation time of the
reactor in the case of standard fuel is 274 days and if the use of
mixed fuel is 135 days.
Biological Denitrification process in anoxic fluidized bed reactor is a simple
way to eliminate nitrate – nitrogen that pollute the groundwater.
In this method the biofilm (including organic bacteria) was cultured on the
reactor bed particles, whi
ch we chose granular activated carbon (1-3) mm.
The raw water containing Nitrate ions and bacteria nutrients was pumped
into the bottom of the reactor in an adequate velocity to fluidize the bed
particles holding the biofilm.
Ethanol and DeHydrogenated Sodium ortho phosphate was chosen as
bacteria nutrients, Ethanol as carbonic nutrient and DeHydrogenated
Sodium ortho phosphate as phosphoric nutrient.
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.
A simple description of the thin film fixed bed reactor (TFFBR) is
given. The work has applied different methods of sedimentation of the
solar catalyst suspension, including a new development of the method
being used to meaure the fixation index a
s well as, the study of the
temperature and mechanicaly - treated surface effects.
The results of original waste water (taken from Barada river -
Damascus) treatment, and a model waste water (with DCAA) treatment,
Using the TFFBR , under SYRIAN climatic conditions, were discussed
too .
