2. Filter beds for on-site wastewater treatment : Towards more reliable estimations of phosphorus retention
Sammanfattning : Phosphorus (P) is an important plant nutrient and essential for life. However, thephosphate rock used for fertilizer production is a non-renewable resource and itsproduction is expected to peak. At the same time, the discharge of P into naturalwaters is causing eutrophication, a severe problem in areas such as the Baltic Sea. LÄS MER
