“…It starts at 30 kmMansouria Rayah, North to Cairo at El-Kanater El-Khayria area, Egypt. El-Rahawy drain lies between latitudes 30 • 10 N to 30 • 12 N and longitudes 31 • 2 E to 31 • 3 E. It is about 12.41 km and passes through El-Rahway village, receives agricultural and domestic wastes from many villages distributed along it, without purification in addition to sewage of El-Giza governorate and discharges these wastes directly without treatment into Roetta branch of the River Nile (El-Sheikh et al, 2010). The drain is surrounded by dense population and wide agricultural lands, while it discharges about 2.8 m/day including 1.9 m/day sewage effluents (Gaber et al, 2013).…”

In this study, the detergent's concentrations in aquatic environment principally drinking and surface water along River Nile and near rural village were determined to report the influence of different physicochemical characteristics on the distribution of linear alkylbenzene sulfonate (LAS) that lead to toxicity in human beings. The removal efficiency of LAS using zeolite and granular activated carbon technique was assessed.The results showed wide variations observed between surface (0.07-0.38 mg LAS/l) and bottom water (0.05-0.17 mg LAS/l) due to increase in population density and human activities that recorded highest concentration along rural area (surface: 1.24-2.45 and bottom: 0.93-1.083 mg LAS/l). Low concentration of surfactants was found in drinking water (0.005-0.007 mg LAS/l) compared to the concentration of the corresponding water samples along the River Nile. In conclusion, the study indicated that the treatment processes for drinking water production were insufficient for the complete removal of surfactants and adsorption process by using zeolite as low cost, most beneficial, economically feasible method as well as easy to operate for producing high quality of water.

“…It is one of the major components of vegetation stands along the shores of Lake Burullus close to the Deltaic Mediterranean coast [14]. T. domingensis is one of the emergent plants most commonly used in constructed wetlands for the enhancement of water quality in water treatment systems [10,15] due to its high growth rate and great capacity for heavy metals accumulation in its tissues [16,17].…”

The concentrations of Ag, Co and Ni in the sediments and the different organs of Typha domingensis from Lake Burullus, Egypt, were investigated monthly from February to September 2010 to evaluate the aquatic environment quality of the lake and to test the suitability of these organs for bio-indicating of sediment metals. The sediment heavy metals were found to decrease in the order of Ni > Co > Ag. The sediment contents of Ag were about 45 times above the worldwide range. On the other hand, Co concentrations were below the reference ranges of United States and Chinese soils. The heavy metals bioaccumulation decreased according to the order of rhizome > root > leaf for Ag; and root > rhizome > leaf for Co and Ni. It was found also that, T. domingensis had no significant differences in heavy metals concentrations over time. The transfer factors of Ag, Co and Ni from sediment to below-ground organs were smaller than one. Co had the maximum transport from below-ground to above-ground organs, while Ag had the minimum. There was a significant linear correlation between the concentration of Ag in root of T. domingensis and that in sediment. This result suggested that T. domingensis can be regarded as bio-indicator for Ag pollution of Lake Burullus.

“…There have been only a few reports concerning the remediation of heavily polluted rivers (e.g. Sun et al, 2009;El-Sheikh et al, 2010;Wu et al, 2011), and most of these studies were focused on off-line treatment or laboratory work (e.g. Palmer, 2009;Cao et al, 2012).…”

a b s t r a c tRiver pollution is becoming a serious problem worldwide. A field-scale experiment was undertaken to remediate a heavily polluted river using a combined engineering approach of aeration, microorganisms, biological aerated filtration, artificial biofilms and ecological floating beds. Prior to remediation, the river water was black, anoxic and highly sulfidic. With remediation, the chemical oxygen demand decreased from ∼250 to ∼50 mg L −1 , NH 4 + -N decreased from ∼27 to ∼4 mg L −1 , sulfide decreased from ∼3 to ∼0.3 mg L −1 , and total suspended solids decreased from ∼270 to ∼40 mg L −1 . At the same time, dissolved oxygen increased from ∼0.1 to ∼3.5 mg L −1 , and water clarity increased from ∼6 to ∼40 cm. Furthermore, the unpleasant odor emanating from the polluted river was also stopped, and local farmers have begun using the water for irrigation. This field-scale experiment thus indicates the potential usefulness of this combined engineering approach to remediate heavily polluted rivers.
