Abstract

Since the semi-arid and dry, access to good water quality is associated with restriction, so exploitation of sewage effluent for irrigation is very important. Nowadays, use of natural materials in water purification and sewage is increasing. One of these materials are seeds of Moringa Peregrina plant. In this research the performance of Alum and Poly Aluminum Chloride (PAC) were compared with Moringa Peregrina seeds powder  in wastewater treatment. The samples of sewage were collected from fluvial that received domestic sewage and used without any pre-treatments. Sewage samples in separate stages were contacted with different concentrations of Moringa Peregrina seeds powder, Alum and Poly Aluminum Chlorides. In these experiments the concentration changes of nitrate, phosphate,turbidity, TDS, electrical conductivity and pH is studied.  Results  showed that the use of showed that the highest removal efficiency of  phosphate and nitrate are  related to Moringa Peregrina, so that 120 mg/lit Moringa Peregrina able to reduce 80 percent of phosphate and 110 mg/lit of Peregrina, reduce 50 percent of nitrate. The results indicated that the use of Moringa Peregrina seeds powder reduced the sedimentation time from 30  to 10 minutes and dewatering of sludge produced was better than the others.
