Evaluation of Bio-Carrier in Attached Growth Wastewater Treatment System

Abstract

Biocarrier is being used more frequently to support biofilm growth in the treatment of wastewater through oxidation of organic particles and nitrification of ammonia. For this experiment the influent was taken from the intake house where the incoming of wastewater around university campus. The clogging problems that occur were observed physically or visually and the thickness of the clogging was closely monitored. In this experiment, the test that carried out was total suspended solid (TSS) and MLSS. With these tests carried out, the TSS and attached growth were obtained. Besidesthat, there were three types of biocarriers were filled in three tanks and the system operated continuously to identify the performance in each configuration. The resulted development of attached growth in Type One showed that the performance is better compared to Type Two and Type Three. In addition, the performance was relevant to the configuration as the bio-balls in Type One were positionclosely so that more bio-balls were fixed in the tank. The Type Two configuration showed similar results as the Type One where the high reduction of suspended solids achieved. In addition, Type Three efficiency did not show positive results as the configuration performed poorly compared to the other two types. During the whole process, there was no clogging occurred and this showed that the configurations presented positive outcome. The attached growth development was monitored weekly visually to determine the clogging.
