1. INTRODUCTION
2.8 Summary
The AD process is a practical and useful treatment technology for FOG-laden PSW.
Although this process has numerous advantages, it is important to select an appropriate reactor configuration to achieve maximum reactor performance at lower cost. The reactor performance in treating such FOG laden PSW is influenced primarily by reactor configuration (i.e. up-flow vs down-flow configuration). The up-flow reactor configurations such as UASB, including the EGSB, are largely dependent on the up-flow velocity which often results in periodical sludge washout during high FOG and TSS loading periods. This exacerbates inadequate reactor performance in comparison to the down-flow reactors such as the SGBR, which achieve higher organic load removal efficiency, particularly due to their ability to retain sludge granules and solidified residue within the reactor, although periodic backwashing is required. The aim of this review was to highlight reactor configuration deficiencies, including advantages, when the AD treatment method treats FOG-laden PSW, using either up-flow or down-flow configured systems, with the ultimate aim of achieving high reactor performance.
