In this study we compare the ability of nitrifying activated sludge (NAS) and nitrifying trickling filter (NTF) wastewater treatment to remove the following contaminants: acetaminophen, caffeine, 1,7-dimethylxanthine, cotinine, ibuprofen, sulfamethoxazole, triclosan, and trimethoprim. Removal of acetaminophen, cotinine and caffeine was greater than 99% and removal 1,7-dimethylxanthine, ibuprofen, and triclosan was greater than 90% using NAS and NTF treatment. Sulfamethoxazole and trimethoprim were inadequately removed in both NAS and NTF treatments. The horizontal, subsurface flow treatment wetland showed removals of 45-89% for sulfamethoxazole and greater than 96% for trimethoprim. There was no statistical difference (P>0.05) between aeration, temperature and vegetation in the treatment wetland for the removal of sulfamethoxazole and trimethoprim.

The aim of this master project is to design a nearly zero-energy building of a guesthouse with a restaurant in the village Vrbice u Velkých Pavlovic. The project contains architectural-construction part and concept of building services. As the third part there is a design and concept of a wastewater treatment wetland system. The building has two floors. On the ground floor there is a restaurant, kitchen, reception and technical facilities, the premises of the 2 nd floor contain guest rooms. The structural system is designed from ceramic blocks with thermal insulation from mineral wool. Horizontal load-bearing structures and stair construction are designed from cast-in-place reinforced concrete. The building has a warm flat roof. The building has a mechanical heat recovery ventilation. For heating and water heating there is a heat pump and a condensing boiler, for cooling there is a multi-split and VRV system. The building also includes a storage reservoir for collecting rainwater and photovoltaic panels on the roof. The building site contains also an outdoor park, storage with carport and a garden with wastewater treatment wetland technologies and biotope lake. The project was carried out by the ArchiCad and Autocad programme.
