dc.description.abstract  Abstract Hydraulic and Purification Behavior during Wastewater Treatment in Soil Infiltration Systems The aim of this work is to evaluate the hydraulic and purification behavior during post treatment in soil sand filters. Moreover, the effect of filtration mechanism of sand filter basin which using in Sheikh Ejleen Pilot Project Plant, and its effect to remove some elements like, Ammonia (NH3) or to provide Nitrate (NO3). The main objectives of this research to correlate the relation between the application rate and the formation of the clogging layer in the sand infiltration system, investigate the effect of application rate on the transformation of nitrogen species in the applied wastewater, and create the best management practice for the slow sand infiltration unit for irrigation purposes. The experiment was conducted at Sheikh Ejleen Pilot Project Plant, which it involving three sand filter and two reed beeds at summer season of 2016. The researcher use one sand filter basin during his investigation. Three different application rates implemented (trial test (1) = 110 m3/h with velocity 1.73 m/s, trial test (2) = 138 m3/h with velocity 2.16 m/s and trial test (3) = 212 m3/h with velocity 3.33 m/s). For each application rate (Trial Test) consists of (11) wastewater samples were collected from the bottom of the sand filter as function of time. Results showed that the filtration mechanism of sand filter basin not adequate enough to agriculture uses. There is unexpected results for Na which found in three Trial tests. The most efficient trial test in three trial tests of NH3 removal efficiency and providing NO3 is trial test (1) with application rate = 110 m3/h and velocity = 1.73 m/s. Although, Ammonia concentration still significant for agriculture uses. Denitrification process unnoticed. Low efficiency for TSS removal in three trial tests which affect clogging in sand filter layers, on the contrary of TSS the BOD5 infiltration system capacity was cleared. So, it recommended to extend the depth of sand filter basin in Sheikh Ajleen Post Treatment Pilot Project, involve backing wash system in the main system, to avoid saturation of soil in sand filter basin and more investigation in Na attitude in sand filter due to the relation with sodium adsorption ratio (SAR) in agriculture.? en_US
