Abstrakt: Constructed wetlands are the man-made system that mimics the function and structures of natural wetland and manipulated for wastewater treatment. The aim of the present study is to investigate the feasibility of using the small scale constructed wetland (CW) that is integrated with six species of plants to treat municipal wastewater in a hotel. The annual water quality improvement performance of four sampling points in the CW cells is described once in mid-January and mid-September from 2009 until 2013. The parameters studied were pH, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), ammoniacal nitrogen (AN), nitrate nitrogen (NN) and total phosphorus (TP). The removal percentage of each parameter was calculated and described as removal efficiency. Loading capacity of nutrients was also calculated using models. Removal percentage of pollutants and nutrients was higher in January compared to September in average due to some factors that are already explained. However, the results proved that the small scale CW can be one of the best alternatives to be used in hotels and resorts among modern and conventional treatments. [ABSTRACT FROM AUTHOR]
