تهدف الدراسة إلى إمكانية استخدام الرماد المتشكل من حرق الحطب و مخلفات التقليم المختلفة في إزالة قساوة المياه . تم في هذا البحث توصيف الرماد ( ناتج عن حرق مخلفات من شجرتي البلوط و السنديان ) لتحديد نسب المكونات الداخلة فيه باستخدام عدة تقانات منها XRD و مطيافية اللهب و المعايرات الحجمية و غيرها . حدد زمن خلط الطورين المثالي عبر وضع كمية محددة من الرماد إلى مياه شديدة القساوة حيث تم معايرة قساوة المياه خلال أزمنة مختلفة ( 0.5,1,2,3,4,5) ساعة و كان الزمن المثالي لخلط الطورين عند3ساعات . عينت نسب الإزالة و ذلك بتثبيت زمن خلط الطورين و بإضافة بشكل مباشر الكميات التالية من الرماد ( 0.5;1;2;3;5;7;10;15;20;25 ) غرام إلى 200 مل من مياه شديدة القساوة و تبين أن نسبة الإزالة تزداد بشكل طردي بازدياد كمية الرماد المضاف و بلغت نسبة الإزالة ما يقارب 50% عند استخدام واحد غرام من الرماد حتى الوصول إلى نسبة إزالة كاملة قدرها 100% عند استخدام 25 غرام من الرماد .
This study aims to use the ash formed from the burning of firewood and the different pruning residues to remove the hardness of water Soda ash was characterized using different techniques, including XRD,flame spectroscopy , volume titration and others. These methods aim to determine the composition of the ash and the components which are contributing to the removal process. The optimum mixing time was determined using certain amount of soda ash to the hard water and the water hardness was determined in the rang of time (0.5, 1, 2, 3, 4 and 5h) where the ideal time was 3 hours. The removal ratios were determined when the mixing time of the two phases was 3 h, and adding directly the following quantities of ash (0.5,1,2,3,5,7,10,15,20,25) g to 200 ml of highly hardened water. The removal rate was increased by increasing the amount of added ash. The removal rate was approximately 50% when 1 g of ash was used and the complete removal rate of 100% was achieved when the amount of ash was 25 g.

Soda ash was characterized using different techniques, including XRD,flame
spectroscopy , volume titration and ot
hers.
These methods aim to determine the composition of the ash and the components
which are contributing to the removal process.
The optimum mixing time was determined using certain amount of soda ash to the
hard water and the water hardness was determined in the rang of time (0.5, 1, 2, 3, 4 and
5h) where the ideal time was 3 hours.
The removal ratios were determined when the mixing time of the two phases was 3
h, and adding directly the following quantities of ash (0.5,1,2,3,5,7,10,15,20,25) g to 200
ml of highly hardened water. The removal rate was increased by increasing the amount of
added ash. The removal rate was approximately 50% when 1 g of ash was used and the
complete removal rate of 100% was achieved when the amount of ash was 25 g.
The changes in coefficient of distribution of lead and cupper has been studied in
system with two phases, liquid water contaminated with lead and copper-solid (natural
Phosphate of Syria) correlation of the following factors: Time of mixing phases,
size of the
developed steel ,change the values of PH ,concentration of elemental lead and
concentration of element capper ,the concentration of calcium as a competitor to the
occupation of sites available on the solid phase, the ratio V\m presents the water phase size
on the mass of phase ,the Percentage removal of lead from aqueous samples prepared in
the laboratory91,57-99,95% were the best conditions for a vast proportion removed can be
summarized as follows:
PH=[6,63-10,11], Time of mixing phases =60 minutes and V/m=1000.
The Percentage removal of copper from aqueous samples prepared in the
laboratory 95,27 -99,96 % were the best conditions for a vast proportion removed can be
summarized as follows:
PH= [7,89-11,01] , Time of mixing phases =60 minutes and V/m=1000.
Ideal conditions have been applied that were obtained according to laboratory tests
on water samples from industrial input to Banias refinery and water samples from
industrial drainage to Syrian company for oil transport after Removal for lead was(
100%,99 %). Removal for copper was( 100%,98 %) .
This research aims to study the effectiveness of each(ferric chloride , ash and coffee
dregs) to remove phosphorus from Lattakia Port Laboratories' waste water which is
assembled in a separate sewage pit by doing laboratory experiments on water con
taining
high concentrations of phosphorus, whether real wastewater or standard solutions of
phosphorus oxide. Where it has been experimenting with ferric chloride at doses as weight
average(FeCl3/P = (0-5)) to give effectiveness ratios(70- 80)% with determining the value
of the pH-compliant and it was noted re-releasing of phosphorus time after(10-12) hours of
the start of precipitation, beside that it has been experimenting with ash as adsorpted agent
at doses as weight average(Ash/P = (2-4.5)) to give effectiveness ratio which it had
reached to 98% where it was noted re-releasing of phosphorus after 11 hours with
determining the pH values of approval for that, As coffee dregs when added in
doses)Coffee dreg/P = 3-10) as weight average, it fulfilled proportion removal(40 - 99) %
and phosphorus re-released after 24 hours. The outcome of these experiments was to
propose the most appropriate economic solution in the case of study.
This invention relates to process for preventing both corrosion and the formation of scale in water- conducting systems which
comprises adding a zinc carbonate and hydroxyl ethylene diphosphoric acid (HEDA) to water.
The main problems arising in hy
draulic engineering, e.g. when
untreated water for cooling purposes are the occurrence of corrosion and the formation of scale.
The corrosion of metals such as steel, copper and alloys of these
metals which commonly used for water circulation tanks is mainly
due to the action of oxygen, carbon dioxide ,chloride gas , chloride ions and many others ions dissolved in the water.
The prevention of corrosion by forming thin film of complex HEDA
and zinc ions which actions with corrosion ions while the
prevention of scale by forming heat stable soluble complexes with
calcium and magnesium.
In the present work, batch electrocoagulation experiments were carried out
to evaluate the removal of polycyclic aromatic hydrocarbon (PAHs) from water
using aluminum electrodes. The effects of initial pH, current density,
electrolysis time, initi
al concentration of PAHs, electrolyte type, and electrolyte
concentration were investigated to achieve the optimal removal efficiency. The
results indicated that the electrocoagulation utilizing the aluminum, as anode
and cathode, was an efficient tool in the reduction of these contaminants. The
treatment process was found to be largely affected by the current density and
the initial composition of water. The removal rate was significantly increased
using NaCl as an electrolyte where indirect oxidation by hypochlorite forming
later during the treatment was occurred. The results demonstrated that the
technical feasibility of the electrocoagulation as a possible and reliable
technique for the treatment of PAHs contaminants in water.
