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.

The present study is an attempt to investigate oil and grease pollution that may pollute fresh water and influence aquatic environment. Then removal of oil and grease from manufacturing wastewater befall essential but common techniques not enough. Enzyme and adsorption units representing major developed new laboratory were selected to assess the water quality and humiliation prospective of oil and grease from wastewater. Several components and environmental variables that were dissolved oxygen, bacteriology measure, flow rate and adsorption material amount studied to assess the removal performance of oil and grease. The results elucidated significant variations among different tests which influenced microbial necessary role of oxidation declining develop biological treatment process reached to 72%. The study stressed out natural material (zeolite) that enhanced organic reduction under optimal conditions. These conditions were closer spacing and high length of adsorbing unit that led to increase oil and grease contact period with adsorbent and added to increase performance removal reached to 99%.
