Abstract
This research was carried out investigate the removed T-P, T-N and anion surfactants using Autoclaved Lightweight Concrete(ALC) in wastewater treatment system. Effects of pH, TDS on aqueous solution was measured. Specific area which measured by BET was $27.66m^2/g$. The phosphorous, nitrogen and anion surfactants removal efficiencies were examined by using artificial waste water(T-P : 66~73mg/L, T-N : 56~136mg/L and anion surfactants : 10~31mg/L). The results showed that the ALC 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 removal system using ALC.
