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.
This study deals with identifying some heavy metals (Pb,Zn,Ni) concentration in the recycledsewage in Latakia Countryside which is resulting from three treatment plants distributed over (Hebbeit, Al-Harah, MarjMoairban),2011.This research uses the El ectro Thermal Atomization-Atomic Absorption Spectrometry (ETA-AAS) technique in determining of heavy metal elements mentioned above. This research shows a higher concentration of Zn-element (2.798 mg/L) in all treatment plants and in all seasons compared with the concentration of other elements, while Ni and Pb have recorded low concentrations (0.351, 0.243) mg/ℓ, respectively. The statistical study has demonstrated that there is a correlation varying from positive high to positive low, and sometimes to negative highs and lows, this gives clear indications for resources of pollution.
This research includes monitoring the distribution of DO concentrations in the Marj Maarban and AL Ruyemih WWTPs which use different types of aeration systems (surface aerators and diffusers). Research has shown a remarkable increase in the values of DO concentrations in the studied aeration basins above 2 mg/l which means an increased electricity consumption and operational problems, in addition to the role of the natural aeration process in reducing the number of aerators operation hours. This will reflect positively on the performance of the plant and the investment cost.
This study was performed at three plants for sewage treatment in Syrian coastal villages: al-Hara, Murj-Muairban, and Hibbeat. Dry sludge samples were collected from drying sludge basins monthly, during the period October 2011-September 2012. We d epended on different global ways to isolate the eggs from the sludge (flotation, sedimentation, filtration through special sieves). The microscopic study results of the sediment showed the presence of 5 different species of the parasitic worm-eggs, belonged taxonomically to five different species of parasitic worms, two species belonged to Nematoda: Ascaris lumbricoides and Trichuris trichura, and three species belonged to Platyhelminthes: one species of them belonged to Trematoda: Schistosoma mansoni, and the other two species belonged to cestodes: Taenia saginata, and Diphyllobothrium latum. The average number of worms eggs isolated from the dry sludge resulting from the three studied sewage treatment plants (al-Hara, Murj-Muairban, and Hibbeat) recorded relatively close values, the most number in the dry sludge resulting from the treatment plant in Hibbeat with an average 97.16% eggs/50g, then al-Hara with an average 75.08egg/50g dry sludge. Also the results showed that the isolated eggs were more diversed in Hibbeat treatment plant, this an indicator of the health status of the population in the studied sites. Study showed that the number and diversity of parasitic worm – eggs use more observed in Summer and Autumn than in Winter and Spring.
The activated sludge is one of the most common methods of sewage treatment , which has been studied through to find the relation between sedimentation properties and the performance of aeration units. sedimentation experiments were applied on a highl y- aerated activated sludge experimental treatment plant .Also, another experiments were applied on Marj Maerban treatment plant which is operated using the extended aeration method in order to find the Factors influencing the settling of activated sludge . These experiments were done using the Sludge volume index (SVI) ,the maximum velocity sedimentation rate (UMAX) and the time corresponding to the maximum velocity of sedimentation (TUMAX).In experimental treatment plant. We found that the sedimentation experimental parameters (Vo, n) are very sensitive and can be changed significantly with changing the values of suspended solids (MLSS) in the aeration tank. The mathematical relationships can be used to predict the value of (Vo, n) as well as designing and selecting the operating system of sludge without resorting to a conventional sedimentation tests . We also found in the extended aeration the maximum velocity sedimentation rate (UMAX) is the most important in settling process as we got some good correlation coefficients (R2) between UMAX and (TUMAX, MLSS, SVI) was at a temperature (20OC) were respectively (98, 96,98%), and when the temperature (17 OC) respectively (97,96,97%) which is almost the same values. We noticed that the sludge volume index (SVI) is closely associated with the settling parameters (UMAX, TUMAX) with the correlation coefficients were respectively (98,99%) on the temperature of (20OC) and (98,97%) on the temperature of (17OC) . Velocity sedimentation rate (UMAX) was the largest and deposition time (TUMAX) was smaller on the temperature of (20OC) Indicating an improved sedimentation with higher temperatures . Subsequently, temperature is an influential factor on deposition and It is necessary to be taken into account in the design and operation of activated sludge treatment plan.
