    • Abstract:
      Water pollution is a problem that often arises and gives a serious impact to the environment. Therefore, it should be reduced by conventional methods or modern methods. The submerged biofilter is a biological waste treatment plant that utilizing microorganisms grown in a packing medium. The advantages of submerged biofilter as a waste treatment plant are easy to use and low energy consumption so the operational cost is cheaper. This study aims to determine the operational parameters of the submerged biofilter and to develop a model that can be used to estimate the rate of elimination of each pollutant using nitrification reactor for ammonia and denitrification reactor for phosphate. The experiments were conducted with draining the wastewater in a cylindrical bio-filter column in which the hight is 90 cm. At first, the microorganism was grown for two weeks with the residence time of one day. Furthermore, the wastewater removals are conducted with hydraulic loading rate (HLR) variation of 0.44; 0.55; 0.74; 1.11; 1.66; 2.21; and 3.32 m3/m2/day. Then the effluent from the outlet is analyzed using UV-Vis Spectrophotometer. The results showed that the optimum ammonia and phosphate removal was obtained in 0.44 m3/m2/day for ammonia removal and 1.66 m3/m2/day for phosphate removal. While the removal of ammonia and phosphate percentage from both conditions are 97.41% and 27.16% respectively. The changes of HLR will give an effect on substrate reduction rate (SRR), and the percentage of substrate removal. The model developed based on efficiency factors presented a good approach to represent the concentration of substrate effluent at various HLR.
