Many chemical compounds (bases, inorganic acids, salts) have been used to find a suitable
solvent for vanadium oxide And determine optimal conditions for its Dissolution.The best
of them was sodium hydroxide at 2M concentration. The solubility was
100% at 90 °C and
the solubilitys time was 30 min. The number of motor cycles was 800 cycles / min and the
liquid / solid ratio was 200 g / L.
In addition,the best amino protonadted compounds were used to precipitate vanadates from
their solutions (monoethanolamine, diphenylamine, hydrazine, hydroxide amine
hydrochloride, urea) with several inorganic acids (HCl, H2SO4, HNO3) and 1: 1 acid/base
was monoethanolamine protonated with concentrated sulfur acid .
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.

This research was conducted in 2016c, at the Zahid Western
Research Station in Akkar Plain region of Tartous Governorate, the
objective of this research is study the effect of non-conventional
organic waste (compost of garbage, sewage sludge) and
cow
manure on the physical properties of clay soil in the region. Wastes
was added to the soil at a rate of (0 - 10 - 20 – 30) t/ha, in order to
determine the effect of the difference in the quantity added on
physical properties of the soil and peanut productivity.
The Bio-mass was isolated from the medium of the water olive
soaking , and was developed on two medium olive mill wastewater
OMW.
The main purpose of the research was to partially replace the
reused substrates with natural preservatives. Five mixtures were
formed with different percentages of the recycled granules (0-
100%) and for constant W/C, and the study of the possibility of
disposal of the ruins of the destroyed buildings through their reuse
in the work of the concrete and the positive effect on the
environment.
In this research, the
antioxidant capacity(DPPH method), and total phenolic content (assayed
by Folin-Ciocalteu method), ,flavonoids, anthocyanins (pH differential
method) and ascorbic acids(2,6-dichlorophenol indophenol) in three fruit
tissues (
peel, pulp and whole fruit), of four apple cultivars commonly in
Syria(Red Delicious, Rome Beauty, Starking Delicious, Golden
Delicious), were studied.
The effect of clay soil treatment with two levels of tobacco west compost and
organic fertilizer (15 and 30 ton/ h), in addition to mineral fertilizer treatment, with three
replicates of each treatment on some physical properties (Aggregate size di
stribution, main
weight diameter, bulk density and porosity) and chemical properties (Organic carbon,
humic and volvic acid and humification index for big and small soil aggregates was
studied.
The results showed that tobacco west compost and organic fertilizer were effective in
increment of soil content of organic carbon, which reached (20 and 26%) for organic
fertilizer, and (39 and 45%) for compost compared to the control, conducing to ameliorate
soil physical properties, where The main weight diameter, stable aggregate rate and soil
porosity were increased. Whereas, bulk density decreased significantly in both treatments
compared to the control. Compost treatment affect soil physical properties more than
organic fertilizer.Mineral fertilizer decreased soil content of organic carbon compared to
the control.
Humic and volvic acids contents were between 2.12 and 74.3 mg/kg aggregates in
the control,and compost treatments alternatively in macro aggregates (> 2mm). Wile,
volvic acid values were between 0.93 mg/kg in control for small aggregates (< 0.25), and
3.17 mg/kg aggregates in mineral fertilizer treatment for (0.25 – 2) aggregates.
Humification index values were less than 2 in macro aggregates, while it was bigger than 2
in small aggregates.
this search has studied to know the effect of addition of three
resources (cows, sheep and poultry) and five levels (0, 7.5, 15.0,
22.5, 30.0) T/h, in some physical properties of soil, and some
characteristics of wheat, class Sham- 4. soil was sel
ected from (0-
30) cm of Ayash village in Dier AZ zour - sandy soil texture. The
experiment carried out in a pot capacity (9) kg using a (RCD) with
three replications.
