The plant is designed as a traditional chemical and biological treatment plant, as a polishing step the effluent is going through a filter bed with Filtralite before it is discharged into a small creek. The filter bed with Filtralite gives low and stable discharge levels.
After three years of operation, the treatment plant removes 99% of the phosphorus, which gives a discharge concentration on 0,06 mg/l.
Filter media used in this plant:
1000 m3 = Filtralite P 0-4 mm
100 m3 = Filtralite NR 4-10 mm
100 m3 = Filtralite NR 10-20 mm
