Description

Reference site for wetland substitution with the robust Phragmifiltre® system.An ordinary vertical flow filter with primary settling tanks had shown clogging effects and was reformed by using Phragmifiltre® two stage system with integrated sludge treatment. The system was imbedded into the excavated wetland cells (http://www.akut-umwelt.de/bin/gwt/krawinkel)and settlings tanks were reused as pumping stations.The treatment performance exceeded expectations from the beginning. Operation at low temperatures below -15 °C was stable and discharge limits were met at all times.Year of reconstruction: 2009
