The efficiency of constructed wetland to treat weak and medium primary sewage effluent was tested under three rates of sewage inflow and two types of growing plants (i.e., leaf cattail and common reed). The capability of the wetland to remove COD, BOD, TSS, TDS and F. coliform from the primary weak sewage increased with decreasing the rate of the sewage inflow from 12 L/hr. to 6L/hr., with litt...
