This study aims to determine the effect of discharge variation on the efficiency of decreasing COD parameters contained in artificial laundry wastewater. In this study used a combination of two biofilter reactor dipped with bio ball media with each condition that is anaerobic and aerobic. Drainage of waste carried out continuously and upflow is the direction of the streamline. The research begins with seeding phase which aims to grow microorganisms derived from domestic IPAL sludge unit then followed by acclimatization phase which aim to adapt microorganism with artificial laundry wastewater. After the acclimatization phase is completed, the running process starts by operating three variations of discharge that is 0.625 l/hr, 0.833 l/hr, and 1.25 l/hr. The results showed that the operation of the three variations of discharge did not give a significant influence in setting aside the COD parameters. The percentage of COD removal achieved by each of these debit operations is 82%, 83%, and 81%. In addition, the combination of anaerobic and aerobic dipped biofilter is also able to eliminate surfactant and TSS with the achievement of 90% average removal percentage.
