The aim of this research is to optimize the selection of the sites of Evaporation
Tanks/Ponds, of Olive Mill Waste Water (OMWW). We have to achieve strict
environmental conditions, which in turn relate to a wide range of factors including
topograp
hy, namely: elevations, rivers, silos, lakes and faults, in addition of those related
to man-made geographical elements: cities, villages, roads, dams, wells and contemporary.
To complete the study and obtain reliable results, we adopt GIS, which requires defining
all of the above factors in the form of a graphical and descriptive environment.
The choice of potential sites is through verification of the required conditions using GIS.
This requires the availability of data specific to each condition, verification of other
conditions through field visits and measurements in the absence of necessary data, and it is
necessary to use the available space images significantly through GOOGLE EARTH for
initial verification of selected sites.
Appropriate technology is used according to the state of the OMWW, and according to the
economic potential of the application of this technology. The main objective of these
treatments is to reduce their load of organic matter. The remaining water will be used to
irrigate the agricultural land. Production of manure and feed of cattle.
The research aims to study the economic efficiency of olive mill wastewater
(OMWW) use in fertilizing olive trees, Which included research sample / 294 / farmer in
Lattakia Governorate, depending on the descriptive analytical method,And found the
results to be to fertilize the olive trees with (OMWW) rents high productivity, Where it
posted a net profit of (33,668) SP / acre / year, while gross margin stood at (61 235) SP ,
The coefficient of profitability compared to the cost of production (about 41.32%)%, while
the profitability coefficient was compared to the capital invested approximately 42.98%.
Determining the best location is a complex process that faces decision makers. In the City of Tartous, Syria, this problem springs while selecting the best location for wastewater treatment plant (WWTP) because of the large number of criteria and co
nstrains and the uncertainty in expert's judgments. To solve this problem, we designed a frame work containing multi-criteria decision making (MCDM) technique that is fuzzy analytic hierarchy process (FAHP) to handle the uncertainty situations and geographical information system (GIS) to determine the best location.
In this paper, the FAHP idea was developed to calculate weights of the criterias, the GIS was used to overlay and generate criteria and suitability maps. The study ends with a map of the best sites for constructing wastewater treatment plants by extended aeration method in Tartous region in Syria.
The study was conducted in 2011 on 6-years-old citrus trees "Washington navel
141". It contained four treatments with three replicates for each treatment. The results
showed that:
The wastewater treatments showed superiority on the control in the
number of
vegetative growth and its length.
The number of inflorescence buds, was increased in the second treatment (irrigation
with 50% treated wastewater +50% normal water) (5. 37) which dominated the other
treatments.
The weight of fruit was affected by treated wastewater irrigation. Second treatment
(irrigation with 50%treated wastewater+50 % normal water) was better than the control
treatment. It was increased by (308. 3 g) compared to (259. 5 g) for the control treatment.
Fruit yield production per tree, was increased by second treatment (irrigation with
50% treated wastewater+50 % normal water) (28. 9kg) compared to (15. 3kg) for the
control.
Treated wastewater irrigation had positive effects in the quality of fruit
(Total sugar %), (T. S. S %) and the coefficient of maturity were increased in second and
third treatment compared to other treatments, while (T. A %) was decreased in all
wastewater treatments.
Resulting backwash water from existing filters, in the water purification plants, is actually thrown in most
cases in water bodies, valleys or discharged into other system without making any benefit from it.
The amount of backwash water is well est
imated to be in average (3-4%) of purified water amount. Even
if this amount is generally not relevant, it can however be considered to be useful in some circumstances,
where the source water is rare or there is no water resource in the region at all.
Treatment of backwash water depends on the reuse need of it, either for drinking or irrigation purposes,
so that the treated water must be in accordance with the water quality standard stated in related
specifications.
In this research, the resulting backwash water purification plant at Roum Dam near Swaida town has
been scientifically analyzed and treated in a plant designed and built for this purpose.
In this paper, the results of experiments are discussed; important facts have been concluded and
economic feasibility for water reuse was determined.
The present study contains results of some experiments that had been
carried out to study the advantage of olive mill waste water (OMW) use ability
and in sugar's factories wastes in Syria as fungi cultures to produce stall-feed
rich in proteins.
The results showed that Geotrichum rich in proteins had been grown and
geminated more rapidly and revealed that inorganic nitrogen additions
(nitrates or ammonia) to the culture have advanced the fungi growth which is
rich in proteins, the highest quantity of proteins was (8.6 g/l) in NH4NO3 (1.5%)
media and urea (2.0%) media whereas the fungi biomass was higher with
NH4NO3 (1.5%) than with urea (2.0%).
This study was conducted to determine the chemical and physical analysis of
two important water sources in the coastal erea, namely: Northern Elkabeer
river and Balloran Dam. The study took a year and a half starting from June
١٩٩٩.
The temperatu
re the cations and the anions were periodically
determined in three sites selected along the river bed.
Results showed, that there are a large variations in the concentrations of the
studied elements, in both water sources. The same variations were also
observed among the three defined sites of the same source according to the
ruling climatic factors during the year. The increase in the concentrations of
most of chemical elements in water source was observed when the temerature
increased. These concentrations generally reach the highest value in the latest
Summer and the beginning of Autumn.
It was shown that the impact of the biogeochemical factors namely: rainfall
and floods, the water drianing from soils and the effect of agricultural and in
dustrial waste - water became clear .
According to the international and Syrian standards of water chimical
qualities, the water of Balloran Dam and ١٦ Tishreen Dam can be used for
drinking and irrigation purposes. While water of the tow studied sites on the
Elkabeer river can only be used for irrigoation.
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 .
