استخدمت في هذا البحث، الأحياء الدقيقة المعزولة من التربة السورية لمعالجة مياه مخلفات المصابغ، و بعض الأصبغة التي يغلب استعمالها، و قد وجد التفاوت الكبير في سرعة نمو الأحياء الدقيقة، كما لوحظ التفاوت الكبير في زوال اللون، إضافة لتثبيط العمل الإنزيمي من قبل بعض الأصبغة، كما درس تأثير تركيز الأصبغة في نمو الأحياء الدقيقة، و زوال لون الأصبغة، و قد اعتمد قي تحليل الرشاحات الناتجة عن المعالجة الحيوية قياس شدة الامتصاص في مجال الطيف المرئي ما بين ٣٥٠-٧٥٠ نانومترًا.
In this study, microorganism separated from the Syrian soil were used in treating the waste water from dyehouse and some dyes which are oftenly applied. A great difference was found in the speed of microorganism growth as well as the great variation in color disappearance, in addition to inactivating the enzymatic work by some of the dyes. Also, the effect of the dyes density on the growth of microorganism. The absorption strength measurment in the field of visible spectrum between ٣٥٠ –٧٥٠ nanometers was adopted for analyzing the filtrates resulting from the biological treatment .

In this study, iron chloride solution ١٠٪ was used as absorbance matter
which absorbs all dyes and the organic substances during its precipitation .
The accumulation of these wastes in nature is considered to be a serious source
of pollution and h
ealth hazard. We determined the optimal pH and the optimal
dose of a minimom number of the reagent used as well as the water of
dyehouse baths, and we compared the difference between using iron chloride
and aluminium sulfate .We adopted the experimental observation in measuring
the results and the strength of absorption within the spectrofield in a wave
length of ٣٥٠ – ٧٥٠ nanometer .
This research was conducted to study the effectiveness of the
variations of magic latin square design, to reduce the value of the
experimental error, in experiences of microbiological (Lactobacillus
acidophilus), and to improve the activity of ran
dom rectangles as
one source of the variations of magic latin square design.
Where they were conducting a random distribution of (6)
treatments supposed to (36) experimental unit test has repeated the
process of distribution (150) times in order to obtain magic latin
squares realized the conditions which show per treatments once in
the row and once in the column, and once in each rectangle within
the one design.
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%).
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.
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.
