Compact Extended Aeration Reactor (CEAR)

This project was conducted to treat wastewater in a single reactor by using the integration of various treatment processes. In other words, the treatment process such denitrification, aeration and sedimentation are combined in a single reactor. The advantages of having this integration system are that the reactor requires less space compared to the conventional wastewater treatment plant. It is essential to have a new developed technology where the usage of space for wastewater treatment plant can be reduced. This study attempts to propose a new type of wastewater reactor which is Compact Extended Aeration Reactor (CEAR). The main objective of this study was to evaluate the performance of the reactor. The project was focusing on aerobic biological oxidation where the organic matter is oxidized in order to achieve a low BOD level in the reactor discharge. The design of the CEAR will focus on the existing extended aeration design and it is adapted and integrated into this project. This project was using a reactor model with overall volume of 0.5 m3 and it is operated with actual biomass taken from UTPSTP. The reactor was feed with synthetic wastewater with inflow of 15 L/d and samples were collected at the input, output and also within of the reactor. The average COD reading for the raw wastewater is set to be 500 mg/L. The parameters that have been chosen are BOD, COD, TSS and MLSS the where percentage reduction for COD result was 82%, 73% of reduction for BOD result and finally 80% of TSS reduction. Most of the results have complied with the DOE standard discharge limit. Therefore, this report has successfully evaluated the performance of the reactor where the result for BOD, COD and TSS percentage of reduction were 73%, 82% and 80% respectively and most of the results have complied with DOE standard discharge limit
