Abstract

Water scarcity is now one of the problems that most affects several countries. Thereby, it can be found in public water supply systems highly vulnerable and also in water treatment systems and sewage. Thus, the gray water feature as a major sustainable potential to try to reduce the costs related to water. Greywater come from the sanitary hydro units, except the sanitary bowl, that is, the water from the shower, washbasin, tanks and washing machines. The reuse of greywater, applied for non-potable purposes, meets the premises of sustainability and the concept of water conservation. Properly designed greywater reuse systems should follow four basic criteria: hygienic safety, aesthetics, environmental protection and technical and economic feasibility. Greywater, when properly handled, this work can be used for non-potable consumption in buildings, for example, discharge toilets, washing floors and patios, sidewalks washing, irrigation of gardens, ornamental uses as mirrors d'water and fountains, since its use provides no health risks to users. This work aims at the treatment of greywater from the laundry eye D'tap water for non-potable reuse. Was addressed in this paper, the characterization and treatment of clear gray water, coming from the laundry eye D'tap water. The lighter gray water treatment system used in the study contained a filter and disinfection with chlorine. Some of the parameters examined during the search period the clear gray water treatment system achieved a very significant reduction.
