Mathematical Dynamic Recirculation Plug-Flow Areal Reactor Models of Subsurface Recirculation Flow Constructed Wetland Wastewater Treatment for Floating Agriculture Using in Greenhouse
The objective of this study was to develop the dynamic modeling of recirculation plug-flow areal reactor recirculation completely-mixed stirred tank areal reactor (RPFAR) of recirculation Subsurface flow constructed wetland (RSFCW) using granular activated carbon (GAC) as a media contained in 11 pots of reed. The ratio of width to : length was >1:4, used area was 0.04 m2, and the initial height of bed 25 cm. The result of the study found that the recirculation ratio: QR/Qin (R) was 7. The hydraulic recirculation time (HReT) was 0.5 hrs for treating waste water. As a result, the efficiency of BOD removal was 88.94%, respectively which cause the second-order-reaction with areal rate coefficient (kA2nd) equals 18.006 m/day, respectively.
