Abstract
Activated sludge model (ASM) is now widely used for wastewater treatment plant design, optimization and operation. Values for parameters to be used are vital for the accuracy of the modeling approach. This study aims to establish the scientific link between typical treatment and biodegradability of different chemical oxygen demand (COD) fractionation of palm oil mill effluent (POME), by means of respirometric analysis and model evaluation. Typical treatment processes are determined by the characteristics and process optimization carried out during POME treatment. POME treatment is operated under dynamic conditions, where the microbial response can include, besides bacterial growth, several COD removal mechanisms, and particularly the... (More)
Activated sludge model (ASM) is now widely used for wastewater treatment plant design, optimization and operation. Values for parameters to be used are vital for the accuracy of the modeling approach. This study aims to establish the scientific link between typical treatment and biodegradability of different chemical oxygen demand (COD) fractionation of palm oil mill effluent (POME), by means of respirometric analysis and model evaluation. Typical treatment processes are determined by the characteristics and process optimization carried out during POME treatment. POME treatment is operated under dynamic conditions, where the microbial response can include, besides bacterial growth, several COD removal mechanisms, and particularly the storage in the form of polymers. Biodegradability-related COD fractionation was characterized as the availability of readily biodegradable (Ss), slowly biodegradable, storage polymer, inert organic matter, and yield of heterotrophic organism. To verify the experimental results, modeling studies have been conducted using the ASM models, ASM1 and ASM3. The models require characterization of POME using COD-fractionation. The characteristics of fermented POME for anaerobic treatment using CODfractionation indicates the presence of up to 35% Ss and COD-fractions due to availability of free fatty acids in POME. However, the percentage of Ss is higher compared to the raw POME, which represents only 10% of the total COD. ASM3 proved to be a better framework to model all experimental results compared to ASM1.
