Landfill leachate treatment by constructed wetlandsIn the south-east of Hamburg surveyors in 1978 detected that major quantities of contaminated seepage water were leaking from the south-western boundary of a former construction waste dumping site (18 ha), which had been closed down and recultivated. Due to the bad smell it emanated, the seepage also had a negative impact on the local recreational area. In a move to solve this inherited problem, the leaking waters were captured and a constructed wetland system was built using the root zone method. This close-to-nature disposal concept, at the heart of which is a reed bed, was put into practice by the city of Hamburg in 1986. Blumberg engineers were commissioned to supervise the operation of the treatment system.   |

Clarification results - mean decomposition rates of selected parameters
After 25 years of operation this close-to-nature landfill leachate treatment plant (constructed wetland) is still operating at a continuously high quality level. In addition, the building and operating costs have been much lower than those of conventional technical procedures. More details are given under: |
