The aim of this paper is to explore the information and analyze the performance of bio ball and spawning brush media in order to compare the findings of the performance of both biomedia by using Monod Model Equation. The integrated fixed film activated sludge (IFAS) process uses aeration and biomedia of spawning brush and bio ball which are placed fixed in the reactors 1 and 2 respectively. The duration of the study was conducted in 10 days which consist of two-phase which the first phase is monitoring water quality parameter and apply the Monod equation to obtain the performance of the biomedia as the second phase. Chemical Oxygen Demand (COD) removal of reactor 2 has a slightly higher average of 61% as compared to reactor 1 with an average of 57.50%. Thus, the COD removal is more consistent in reactor 1 compared to reactor 2. From this results concluded that IFAS system has a good performance in I terms of low loading wastewater sources.
