Wastewater Process using Porous Ceramic
This study was carried out investigate the removed T-P, T-N and anion surfactants using SiO2-Al2O3-CaO type porous ceramic in wastewater treatment system. The phosphorous, nitrogen and anion surfactants removal efficiencies were examined by using artificial waste water(T-P : 115~170 mg/L, T-N : 56~163 mg/L and anion surfactants : 10~31 mg/L, BOD : 200 ppm, Turbidity : 950NTU). The results showed that the ceramic was effective material as a adsorbent due to the structure and porosity. It was found that anion surfactants removed was 85~95%, phosphate removed was 92% and nitrogen removed was 90% in artificial wastewater. Agitation process was more effective than aeration process in that case of nitrogen system using porous ceramic.
