Biodegradation Model of Dissolved Organic Matter during River Bank Filtration, Al Qurin, Sharkyia, Egypt

Riverbank filtration carry out with natural conditions and also may be occur by lowering of the ground water stream under the surface water levels either by hydraulic boundaries such as bank of channels, or by groundwater abstraction at pumping wells. In addition, the mixing of the infiltrated river water with groundwater at the pumping outlet well, the retention time of the bank filtrate has been studied and identified as one of the key parameters that determinate the efficiency of riverbank filtration and water quality. Previous studies have reported that the level of organic matter and other contaminants reduced with high pass through time. RBF water results of pH, conductivity, TDS, hardness, color, alkalinity, nitrate, nitrite, phosphate, silica, sulphate, chloride, and turbidity were complying with the Egypt and WHO guidelines. The present study showed that, the data of iron and manganese of ground water in the study region, didn`t comply with Egyptian regulation (Fe more than 0.3 mg/l and Mn more than 0.4 mg/l). The results of river surface water quality didn't comply with Egyptian regulation in some parameters such as, microbiological parameters (total bacterial count more than 5000 CFU/ml) and also the examination of river surface water samples were positive in total coliform and fecal coliform examination. The study has showed that, the water quality results from the RBF water had high water quality especially in values of Fe & Mn and also microbiological parameters. The correlation coefficient between DOC recorded and DOC estimated was very strong (r was 0.94).
