Abstract
Decreasing of freshwater is one of the biggest problems that faces Egyptian and international society as well, where increase in water consumption with population growth, rare rain with high evaporation, evolution of living, expansion of agricultural areas, and industrial projects, all push scientists to search about non-traditional resources of water. Since most daily activities don’t required fresh water, it was necessary to find another source of water that can meet these proposes to save a high amount of freshwater consumed in such activities. One of the suggestions to find a new water resource is the reuse of greywater as non-potable water to face the continuous pressure on water consumption. In this study an experimental treatment unit has been tested and evaluated from the greywater treatment efficiency point of view. The filtration method using both up-down and down-up flow is selected to treat the greywater. Based on the analysis of the results of the experimental work; it was found that using sponge as filtration media is the most efficient strategy comparing with others for greywater treatment. The removal efficiency of evaluated parameters for sponge filter were; 98.8%, 86.91%, 67.90%, 71.15%, and 86.36% for TSS, Turbidity, COD, Nitrate, and Phosphate respectively. This treatment unit can be used for treatment of light greywater efficiently, and its effluent can be reused at least in toilet flushing and irrigation of green areas, saving huge amount of fresh water. Greywater reuse is highlighted because its participation in water resources conservation.
