Sludge Reed Bed Systems



Question 1: How is the dewatered sewage sludge practically being removed from the reed bed sludge systems after 10 years?

Question 2: What are the time periods for loading and clearing of the sludge reed beds?

Question 3: Do sludge drying reed beds with marsh plants work also for anaerobic faecal sludge management (FSM) from septic tanks?




 


Answer to Question 1: How is the dewatered sewage sludge practically being removed from the reed bed sludge systems after 10 years?

For example by longarm excavators:



This is the view on the sewage sludge reed beds in Ilsede Groß Lafferde, shown above in the cross section.






At small scale plants with ordinary excavators, for example here in Ilsede Münstedt.







Answer to Question 2: What are the time periods for loading and clearing of the sludge reed beds?






Answer to Question 3: Do sludge drying reed beds with marsh plants work also for anaerobic faecal sludge management (FSM) from septic tanks?

Yes! An example from Germany is the faecal sludge drying reed bed plant for the villages of Offensen-Schwachhausen-Nordburg in the municipality Flotwedel.


An example from India is given under this link.
