The effectiveness of the wastewater treatment plant in Västankvarn when processing slaughterhouse and normal wastewater

Abstract

As part of the modernization of the wastewater treatment plant in Västankvarn, the authorities required that the efficiency of the treatment plant in removing nitrogen, phosphorus, suspended solids and BOD was assessed and confirmed. The nearby slaughterhouse causes additional load. By taking wastewater samples and analysing them in the laboratory, it was determined that the wastewater treatment plant successfully treats the wastewater, despite the high load of wastewater from the slaughterhouse.

The work was carried out for 5 months. The results obtained after laboratory analysis allow us to confirm the effectiveness of the treatment facilities. The new treatment plant is able to significantly reduce the load of phosphorus, nitrogen and suspended solids, well below the required thresholds and thereby reducing the nutrient load on the environment.
