PURPOSE: A low concentration reverse osmosis membrane-based system for treating wastewater generated from an ammonium sulfate fertilizer manufacturing process is provided to prevent environmental pollution due to draining water. CONSTITUTION: A system for treating wastewater generated from an ammonium sulfate fertilizer manufacturing process includes a treating bath(20), a wastewater supplying line(30), a treated water discharging line(40), a concentrated water discharging line(50), and a concentrated water storing tank(60). A reverse osmosis membrane(10) is installed in the treating bath. The wastewater supplying line is in connection with the front side of the treating bath and supplies wastewater to the treating bath. The treated water discharging line is in connection with the rear side of the treating bath and discharges treated water through the reverse osmosis membrane to the outside. Concentrated water obtained from the discharge of treated water is discharged through the concentrated water discharging line. |
