| titleOfInvention | Method for removal and recovery of nitrogen compounds in the wastewater from ammonium sulfate fertilizer production line using reverse osmosis membrane system |
| abstract | The present invention relates to a method for removing and recovering nitrogen from wastewater and wastewater generated in a fertilizer production process using a reverse osmosis membrane system, and a process configured to connect a reverse osmosis membrane in series or in parallel, which has advantages of small size, simple operation, and easy operation. In the present invention, the treated water and the concentrated water that have passed through the reverse osmosis membrane are retreated to maximize the amount of treated water and minimized the amount of concentrated water to meet the discharged water discharge standard, while recovering the nitrogen in the concentrated water as much as possible. Regardless of the type of nitrogen source, it can effectively reduce the nitrogen concentration in the wastewater while using the site.The treated water can be recycled as process water because organic matter is removed from the nitrogen source. Can be reused In addition to reducing the environmental burden of water treatment, there is an outstanding effect that can create added value. |
