Age of constructed wetland and effects of wastewater treatment
A. Salvai, J. Josimov-Dunderski, J. Grabic, A. Belic
Abstract: Constructed wetland with subsurface flow in Gložan (Vojvodina Province - Serbia) is designed to accept and treat municipal wastewater from settlement. Four-year study of removing suspended solids and BOD5 has found that the age of the constructed wetland in the study period does not affect the concentration of suspended solids and organic compounds in the effluent. Applying Fisher F-test and Student t-test tested the homogeneity of data determined that the age of the constructed wetland is not affected, and that the removal of suspended solids is up to 96 - 93% and lowering content of organic compounds, expressed via BOD5, is up to 84 - 79%.
