The corrosion of biogas pipes and equipments damage as generators, boilers and coprocessors is one of
the most real important problems in Damascus wastewater treatment plant (at Adra region). These
problem caused high financial losses and costs , t
hat it required studying and solving. Biogas is the result
of an aerobic digestion process of sludge, it contains about 50-70% of methane as a main resource of
power, where the biogas considers free when it release spontaneity. Different analysis have been occurred
on the biogas to show its components, tests on the pipes material and analysis of sediment material inside
the pipes that caused by biogas.
This research has included quarterly and periodically physical and chemical analysis of treatment wastewater in the Latakia countryside during year 2011 by testing three treatment plants similar in the mechanism of action and distributed in three v
illages (Happit, Al-Harah, Marg Moairban).
This study has included the measurement of temperature, pH, dissolved oxygen, turbidity, and determination of nitrate, phosphate, sulfate, and chloride.
In this research, potentiometric using Selective Electrodes ISEs, the Visible Spectrum, and the Turbidimetry methods were used.
The results showed significant differences in concentrations of the studied ions between one station to another. The highest nitrate concentrations (228.33mg/l) were recorded in Happit treatment plant especially in summer, and the highest phosphate concentrations (41.81mg/l) were in Happit treatment plant in summer. Whilst the highest sulfate concentrations which ranged between (508.67– 1157.33)mg/l were in Al-Harah treatment plant at all seasons. The highest chloride concentrations (310.33mg/l) recorded in Happit treatment plant in summer.
The statistical study has demonstrated and showed high and sometimes low correlation coefficient R2 so that gives clear indications about the sources of pollution.
This research has included quarterly and periodically physical and chemical analysis
of treatment wastewater in the rural areas of Latakia city during year 2011 by testing
three treatment plants similar in the mechanism of action and distributed in
three villages
(Happit, Al-Harah, Marg Moairban).
This study has included the measurement of temperature T, pH, and determination of
sodium, potassium, calcium concentrations, and sodium adsorbed rate (SAR).
This study was based on the potentiometrictechnic using Ion Selective Electrodes
(ISEs).
SAR measurements have shown that there are clear differences between autumn and
other seasons, and between treatment plants. The highest values was in the Happit
treatment plant in all seasons and the highest value was (88.25 mg/L) in the autumn which
is much larger than the allowable limit.
The highest concentrations of sodium ion were in the autumn in all treatment plants
(1002.67-7130.33) mg/L, which is off limits. As for the potassium ion concentration was
highest (72.46 mg/L) in Happit treatment plant in the autumn. While calcium ion
concentrations in Al-Harah treatment plant was exceeded (670.33-800.00) mg/L the
allowable limit in all seasons except the summer.
The statistical study has demonstrated and showed strongand sometimes weak
correlation coefficient R2 so that gives clear indications about the sources of pollution.

As a result of increased environmental awareness and interest in the effective protection
of the environment from pollution, the restrictions have increased on the disposal of
wastewater, and the need to the treatment plants has arisen to treat the
wastewater prior to
disposal in water bodies, whether water from either large or small communities. As a result of
the importance of these facilities and cost of material massive construction, operation and
maintenance. In order to facilitate the design process and calculate the initial cost it was issued
some software that helps engineer in the design of the various parts of the station, and in order
to choose the equipments and comparison between several alternatives in objective ways to
choose the most appropriate. Some of these programs are dynamics. It has the ability to
simulate the work of the treatment plant along the time and predict its efficiency and
performance. STOAT is a software that aims to model and simulate wastewater and industrial
wastewater treatment plant, and it is one of the newest technology that uses the latest
developments in process modelling, simulation and a wide range of tools that simplifies the
model building and simulation and give the results in graphics and tables, allowing us to
examine the complex interactions between the various units within the station by interactive
and dynamic methods and this is important for the effective design, operation and management
of wastewater treatment plants. Hence, we take the coastal area as a case study where there are
number of modern wastewater treatment plants of small agglomeration and is being work, as
Kherbet al-Maaze wastewater treatment plant in Tartous. Using STOAT, the study shows a
good efficiency and performance of Kherbet al-Maaze WWTP using (ASM1,ASAL1) models,
and we could build several scenarios like arrival of high pollution load to the station in order to
evaluate and predict its performance.
