The study relied on two types of data, which are the published and unpublished secondary data issued to some authorities, such as the Ministry of Agriculture and Land Reclamation, and the primary data through the questionnaire formThe study concluded that the net revenue unit from the water unit for the woody trees represented in eucalyptus, kazorina, and pine, It amounted to about 34.18, 29.80, and 29.3 pounds for each unit of treated wastewater, while this net decreased for each of Kaya, Conocarpis, and Neem trees, reaching about 3.17, 7.3, 8.2 pounds for each unit of treated wastewater, as for the net revenue It reached about 44.33, 42.25, 38.92 pounds per unit of waterThe treated sewage for each of the casuarina, eucalyptus, and pine trees, while the revenues decreased for each of the neem, conocarpus and kaya trees, which amounted to about 17.94, 15.84, 11.59 pounds for each unit of treated wastewater, and the amount of water needed to produce a ton of wood from wooden trees was about 52.06, 34.95, 215.62, 113.63, 59.09, 78 m3 for each of the camphor, casorina, and kaya trees, Conocarpus, pine and neem, respectively Treated wastewater, partial and overall efficiency, financial evaluation criteria, sensitivity analysis | ||
