Groundwater treatment plant for the purification of MKW and PAH

Groundwater purification of nuclear power plants and PAH. The extracted groundwater first enters the raw water supply through light and heavy material separators. The process water is then passed over two gravel filters for the retention of iron precipitates and suspended solids.

The remaining pollutants are cleaned off via activated carbon filters, which are connected via replaceable piping. The pure water is enriched with nutrients before seepage to support biological purification processes in the soil. The nutrient solutions for biological purification are prepared in a mixing plant, temporarily stored, and metered via dosing pumps.

The system is equipped with a PLC and remote access, which means that, for example, backwashing processes and conveying regimes can be carried out fully automatically and monitored and controlled remotely. For frost protection reasons, pure water, backwash wastewater, and nutrient tanks are designed as earth tanks. The above-ground system components are also designed to be frost-proof (insulation and trace heating).
