چکیده مقاله:

The nitrite, nitrate concentration and total dissolved solid (TDS) in Well water Surkan Drinking of city of Saveh are too high for human consumption. Therefore, an urgent need for water denitrification and water desalination exists in this well. Reverse osmosis (RO), can be very effectively applied for water denitrification. RO technology has been selected for this study because it can be very effectively applied for water desalination.Nitrite, nitrate was reduced from 105 mg/l in the RO feed to only 7.462 mg/l in the RO product water. The TDS of the RO feed was reduced from 2217.90 mg/l to 24.5 mg/l in the RO permeate. Therefore, an excellent quality water could be produced for potable purposes. Concentration of nitrite, nitrate were determined by photometer. Then, a system designed and modeling with a reverse osmosis system has been referred to as an Integrated Membrane System (IMS) software.The pilot was equipped with flow meters, pressure gauges, and collection ports so that the performance of the six elements in vessels could be monitored separately. Vessels were equipped with commercial model CPA3 with size 8×40 and higher rejection. Modeling of nitrite, nitrate removal by membrane confirmed the experimental results.
