Abstract

Triclosan is one type of emerging contaminant that pollutes water bodies due to the use of personal care products (PCP). Constructed wetland (CW) is one technology that can remove emerging contaminants and nutrients from domestic housing activities. Up to now, the filter media used in CW are gravel, sand, and soil. This study investigated the effect of using a polymer as a filter media in CW on the removal efficiency of triclosan, ammonium, nitrate, phosphate, and chemical oxygen demand (COD) and bioelectricity production. The variations of media used were polymer media, gravel, and a combination of polymer and gravel. The plants used in CW reactor is Typha angustifolia. Experiments were performed in 10 CW reactors with domestic synthetic wastewater nutrients. The reactor runs with a batch system with a detention time of 4, 8, 12, and 16 days. Our results show that mixed polymer and gravel media could provide maximum efficiency in removing triclosan, ammonium, nitrate, phosphate, and COD.
