ترجمة الملخص

In this Research, study of water treatment is a formula that simulates in some of its properties groundwater, using the anion exchange where the following were done. The final concentration of nitrate was measured every hour of the machine until the depletion of the resin at a primitive concentration of nitrate (100 mg / L) and water flow (0.3 -0.54 -0.72 -0.9) l / min. Water nitrates were present in the water with sodium hydroxide on the surface of the resin. The final concentration of nitrate (20.1-23.2 -27.6 -33.1 mg / L) was determined respectively. The final concentration of nitrate in treated water remained almost constant during the resin cycle and is safe to drink in depends on of concentration of nitrates according to the Syrian standard. The final concentration of nitrate was measured every hour of the machine until the depletion of the resin at a primitive concentration of nitrate (150 mg / l) and the water flow (0.3 -0.54 -0.72 -0.9) l / min. The nitrates of water were present with sodium hydroxide on the surface of the resin. The final concentration of nitrate was 40.7 -43.5 -47.3 -53.1 mg / L respectively. The final concentration of nitrates in the treated water during the resin cycle was stable and suitable for drinking in nitrate concentration according to standard Except for the value of 53.1, ie, at the flow of 0.9 l / min is not valid Drinking water. The final concentration of nitrate per hour was measured from the work of the device until the depletion of the resin at a primitive concentration of nitrate (200 mg / L) and water flow (0.3 -0.54 -0.72 -0.9) l/ min. Water nitrates were present in the water with sodium hydroxide on the surface of the resin. The final concentration of nitrate was 85.6-90.3-94.1-99.2 mg / L respectively. The final concentration of nitrates remained in the treated water during the irrigation cycle. It is not suitable for drinking in terms of concentration of nitrates according to the Syrian standard. we Notice that for water with a primary concentration of 200 mg / l nitrate, it can not be treated with anion exchange in previous flows to obtain safe drinking water according to the Syrian standard .The efficiency of nitrate removal was studied when the water was passed in the opposite direction at a primitive concentration of 100 mg / l and flow (0.3 -0.54 -0.72 -0.9) l / min and measuring the final nitrate concentration using the Spectrophotometer and calculating the efficiency of removing the nitrate every half hour The final concentration of nitrate (20.2 -23.4 -28.1 -33.5 mg / l) was the final concentration of nitrates in the water treated during the resin cycle, which is safe to drink in depends on concentration of nitrate according to the Syrian standard .The efficiency of nitrate removal was studied when water was passed in the opposite direction at a primitive concentration of 150 mg / l and flow (0.3 -0.54 -0.72 -0.9) / min and measuring the final nitrate concentration using the Spectrophotometer and calculating the efficiency of removing the nitrate every half hour The final concentration (40.9 -43.7 -47.3 -52.2 mg / l) was final and the final concentration of nitrate in the treated water remained almost constant during the irrigation cycle. It is safe to drink in terms of concentration of nitrates according to the Syrian standard except the concentration of 52.2 mg / Drinking according to the Syrian standard .The efficiency of nitrate removal was studied when the water was passed in the opposite direction at a primitive concentration of 200 mg / L and flow (0.3 -0.54 -0.72 -0.9) / min and measuring the final nitrate concentration using the Spectrophotometer and calculating the efficiency of removing the nitrates every half hour of the work of the machine Final Concentration of Nitrates (85.9-90.6-94.6-99.8 mg / l respectively) The final concentration of nitrates in treated water remained almost constant during the irrigation cycle, which is not suitable for drinking in nitrate concentration according to the Syrian standard .We Notice that if the direction of the flow of water has been changed, the final concentration of nitrate has not changed either in direct or reverse direction. The previous trial sequences were reintroduced with raw water with a primary concentration of 100 mg / l nitrate and flow (0.3-0.54 -0.72 -0.9) l / min where pH was reduced to 6 with sulfuric acid concentration of 2%, where the final concentration (25.3-28.1) -30.7 -33.9 mg / l respectively, and the final concentration of nitrate in the treated water remained constant during the irrigation cycle, which is safe to drink in depends on concentration of nitrate according to the Syrian standard. The previous trial sequences were reintroduced with raw water with a primary concentration of 150 mg / L and flow (0.3-0.54 -0.72 -0.9)L/ min where pH was reduced to 6 with sulfuric acid concentration of 2%, where the final concentration (44.2-47.6-50.1-53.7 mg/ L 97respectively, and the final concentration of nitrates remained in the water treated during the irrigation cycle. It is safe to drink in terms of concentration of nitrates according to the Syrian standard except for concentrations (50.1-53.7 mg / L) 0.9) l / min is not suitable for drinking in depends on of concentration of nitrates according to the Syrian standard
