Résumé partiel
Fresh water scarcity continues to present itself as an underlying global problem as we steadily approach 2025 (UN 2006). Egypt is no exception to the rule, facing several water pollution problems extending from all sectors in the country and negatively affecting water quality and public health. According to the Ministry of Water resources and irrigation (1997), the average water uses in the Egyptian household comprises 18% for shower and bath, 18% for toilet flushing, 8% for laundry, 14% for dishwashing and drinking, 10% for cooking, 30% for irrigation and 2% for other activities which makes onsite treatment and reuse of greywater an attractive option to bridge the gap between water demand and supply in Egypt and help build biophilia settlements that are ecological and sustainable. The main research aim of this work was to study the potential of water hyacinth for removal of organic pollutants and pathogens from residential greywater using aquatic filtration pilot scale system in order to yield water suitable for irrigation of residential lawns. The different experiments of the current work were conducted in five phases at the facilities of the American University in Cairo (AUC).
