Sludge dewatering reed bed in Al Khor industrial area Dubai, 2007 – 2012. The reed bed was used to dewater and mineralize the septic sludge from a labour camp. Solar panels were installed above the reed bed. Outflow water from the reed bed was used to spray the solar panels for cooling and cleaning.
For the Bauer-Group Mizanconsult did the design and construction supervision of 4 test sludge dewatering reed beds in As Slat, Jordan.
4 conventional drying beds were converted into sludge dewatering reed beds.
