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.
