The research into the treatment of domestic wastewaters originating from Büyükdöllük village in Edirne Province was carried out over a 3 year experimental period. The wastewaters of the settlement were treated using a constructed wetland with subsurface horizontal flow, and the effects of different hydraulic loading levels on removal efficiency were studied. In order to achieve this goal, three equal chambers (ponds) of 300 m2 each were constructed and planted with Phragmites australis. Each of the chambers was loaded with domestic wastewater with average flow discharge creating hydraulic loading rates of 0. m3 day-1 m-2; 0.075 m3 day-1 m-2 and 0.125 m3 day-1 m-2, respectively. According to the results of the study, the inlet levels of the pollutant parameters with carbon origin in the water samples taken from the system entrance are high and the average values for three years are respectively: Biological Oxygen Demand, BOD5 -324.5 mg L-1; Chemical Oxygen Demand, COD -484,0 mg L-1; suspended solids (TSS) -147.3 mg L-1 and Oil and Grease -0.123 mg L-1. It was also determined that the removal rates of the system were closely dependent on the applied hydraulic loading levels and the highest removal rates of 64.9%, 62.5%, 86.3% and 80.34% for BOD5, COD, TSS and Oil and Grease, respectively, were determined in the pond with a hydraulic loading rate of 0.050 m3 day-1 m-2. Lower removal of 57.9%, 55.5%, 81.4% and 74.5% for BOD5, COD, TSS and Oil and Grease were recorded in the pond with a hydraulic loading rate of 0.075 m3 day-1 m-2; and these values were 49.1%, 47.8%, 70.9% and 62.1% for the pond with a hydraulic loading rate of 0.125 m3 day-1 m-2. High removal rates were also recorded for the other investigated pollution parameters. © 2015 Elsevier Ltd.

The research into the treatment of domestic wastewaters originating from Bykdllk village in Edirne Province was carried out over a 3 year experimental period. The wastewaters of the settlement were treated using a constructed wetland with subsurface horizontal flow, and the effects of different hydraulic loading levels on removal efficiency were studied. In order to achieve this goal, three equal chambers (ponds) of 300m(2) each were constructed and planted with Phragmites australis. Each of the chambers was loaded with domestic wastewater with average flow discharge creating hydraulic loading rates of 0.m(3)day(-1)m(-2); 0.075m(3)day(-1)m(-2) and 0.125m(3)day(-1)m(-2), respectively. According to the results of the study, the inlet levels of the pollutant parameters with carbon origin in the water samples taken from the system entrance are high and the average values for three years are respectively: Biological Oxygen Demand, BOD5-324.5mgL(-1); Chemical Oxygen Demand, COD-484,0mgL(-1); suspended solids (TSS)-147.3mgL(-1) and Oil and Grease-0.123mgL(-1).
