Abstract
During the last two decades most of the research on SBR focused on the experimental aspect of design and operation. Until today mathematical description of the SBR has not been given much attention. Compared to conventional activated sludge system information on mathematical expression of SBR system is scarce. However it is necessary to develop mathematical description on SBR to improve the design and performance of the system as well as for prediction purposes. In this study a simple mathematical model for substrate utilization of SBR treating MDF processing wastewater was developed. The SBR operation consists of five consecutive modes: fill react settle draw and idle which takes place in the same tank. It has been proven to be a cost effective and efficient system for medium strength wastewater. Sludge seed obtained from a sewage treatment plant in Batu Ferringhi was introduced into the wastewater. The sludge was allowed to acclimatize for two months before the SBR operation began. Substrate utilization was evaluated by measuring the COD for every treatment batch. Organic loading was varied from 2 000 mg/ to 6 000 mg/ of COD. When the SBR system achieved steady state with a constant COD residue the COD profile was recorded. A simple mathematical model that takes into account the inhibition effect has been developed to explain the trend of substrate utilization during the react mode.
