Residential Graywater Treatment Through Phytoremediation

In a globalized world with information on environmental issues, it is observed an increasing number of researches focusing on issues related to soil and water pollution. In this context, the reuse of domestic waters (gray waters) for reuse in agriculture with ecological technology, appears as one of the alternatives to equate water demand and supply, especially in the caatinga biome of the semiarid northeast, characterized by low rainfall. Several techniques are being studied and phytoremediation among the other techniques has had a differentiated attention due to its efficiency and low cost. This study is based on the literature review of several works developed in Brazil and in the world, all related exclusively to the theme. This Review was developed through the analysis of the available material on the in the international databases SciELO, Science Direct, Springer Journal, Embase and PubMed, as well as dissertations and theses that were developed in the area of the use of phytoremediation for effluent treatment.
