In this study, the performance of arsenic and antimon discharge of the iron-containing drinking water treatment facility (DWTS) was studied. DWTS is modified by holding under thermal purification at three different temperatures (200, 400 and 600oC) (DWTS-200). 200oC, 1 hour thermal processing is achieved with the maximum arsenic waste of the applied material. The surface area of the material and the portion volume are analyzed by the BET method, the phase composition is determined by X-ray diffraction (XRD). Surface morphologies and element analysis are performed with scaned electron microscope (SEM) and X-ray spectrometer (EDS). The results showed that the DWTS-200 material has a fairly high surface area (170 m2 g-1) and its amorphic structure is overwhelming. The main phases of the material consist mainly of iron, calcium, oxygen and quartz. It has been determined that 6,000 L for arsenic (133,000 bed volume) and 640 L for antimon (14,000 bed volume) can clean water until it reaches the breakdown point for 40 μg As L-1 and 80 μg Sb L-1 concentrations. Thomas and Yoon-Nelson models have been applied to determine the kinetic parameters necessary for colon design and to predict breakdown curves. Both models have been found suitable to explain the dynamic behavior of the adsorption process. With the Thomas model, the maximum adsorption capacity for arsenic was achieved at 6.53 mg g-1, 5.21 mg g-1 for antimon. Additionally, DWTS-200 adsorban material has been applied for regeneration and it has been shown that the material can be used by regeneration.
