استخدم في هذا البحث محلول كلور الحديد ١٠ % كمادة مخثرة تمتز في أثناء ترسبها كل الأصبغة و المواد العضوية الضارة بالبيئة . يؤدي تراكم هذه الفضلات إلى تلوث البيئة و هي خطرة على صحة الإنسان. و يركز البحث على تحديد القيم المثلى و الجرعة المثالية لعدد كبير من لأصبغة المستخدمة و مياه أحواض المصابغ ، و قارنا الفرق بين استخدام كل من كلور الحديد و كبريتات الألمنيوم ، و اعتمدنا في تقييم النتائج على ملاحظة زوال أو تناقص اللون و كذلك على قياس شدة الامتصاص الضوئي في المجال المرئي عند طول موجة 350-750 نانومترًا .
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 health 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 .

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 variati
on 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 .
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.
The research has been conducted in different sites in lattakia, Alhamra and alsabahia
villages of Rabea and Aen alzarqa of Mashqeta. 14 cases of precipitation was marked
which caused runoff and water erosion of soil during the research (seasonal ra
infall in
2011/2012). Samples of rain water of every precipitation case were collected. by using rain
gauges that were installed in the research sites. After that, samples were moved to the
laboratory. The pH was determined after that the samples were analyzed by using an ion
chromatography device(IC).
This research was performed to study the effect of sewage water on
the surface water of the Addelbeh Valley stream, and groundwater
on both sides of the stream in Tartous Cement Factory area.
Water samples were taken from the factory water outlet
and
Addelbeh Valley water to study the content of pollutants. We also
took groundwater samples from selected wells on both sides of the
waterway in the studied area. We repeated that process every two
months for a full hydrological cycle from July 2013 to May 2014.
We found a great increase in content of the industrial drainage
water include oils and heavy metals especially iron, copper and
zinc. For example: iron concentration in sewage water exceeded
150 mg/l in all samples. Besides sewage water and stream water
contained high concentrations of ammonia and nitrite versus low
concentration of nitrate, unlike water wells samples. The study
revealed increased EC and salts concentration markedly in wells
water due to its adjacency to the sea.
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%).
