Abstract

Purpose: The treatability of synthetic molasses wastewater with the upflow anaerobic filter system in different filter material packing ratios, operation modes, and organic loading rates was investigated. In addition, a modeling study was carried out to analyzed anaerobic degradation proseses for AF100 continuous mode experimental operating parameters by implement the ADM1 directly in PHREEQCI.Theory and Methods: Reactors with different filter material packing ratios were operated at OLRs of 0.5-2 kgCOD/m3.day, 2 days of HRT. Experimental data were compared with ADM1 based PHREEQC model results in order to investigate anaerobic digestion mechanism in filter system.Results: According to experimental study results, while OLR increased, treatment efficiency decreased. Acceptable removal efficiencies were achieved in anaerobic treatment of wastewater for continuous operating mode and filter material packing ratio greater than 75%.Conclusion: In the combination of ADM1 model and PHREEQCI software is a powerful tool that can provide crucial decision support in understanding and solving problems in laboratory and industrial scale anaerobic treatment systems.
