Abstract
Fecal sludge (black water) is a source of pollutants consisting of organic material and microorganisms such as bacteria, viruses, and others. Based on the Ministry of Public Works & Public Housing BOD, TSS, COD, TDS and Ammonia which need to be processed first before being discharged into water bodies or rivers. One of the treatment processes that can be used to treat sludge is the Moving Bed Biofilm Reactor. The independent variables used in this study were variations in volume of media filling, namely 15%, 30%, and 45% and variations in height time (oxic and anoxic processes), namely 3 hours 3 (Oxic 1.5 – Anoxic 1.5), 6 hours. (Oxic 3 – Anoxic 3), 9 hours (Oxic 4.5 – Anoxic 4.5), 12 hours (Oxic 6 – Anoxic 6) and 15 hours (Oxic 7.5 – Anoxic 7.5). The parameters tested were COD, TDS, and Ammonia. In this study, a preliminary process was carried out, namely the process of seeding and acclimatization, then continued with the main research process. In the main (continue) research conducted to obtain the ability of the MBBR reactor to set aside the parameters that have been determined, the volume of media filling, and which residence time is the most optimum. Aerob/oxic conditions run by turning on the bubble aerator and submersible pump and maintaining dissolved oxygen (DO) conditions so that they are > 2 mg/L, after that they are continued with anoxic conditions by turning on the submersible pumps only and maintaining dissolved oxygen (DO) conditions so that they are < 2mg/L. From the research results it can be seen that the fill volume with the best percent removal is found in media filled volume of 45% which can reduce COD by 89.64%, TDS by 79.64%, and NH3-N by 95.76%. The variation of residence time for 15 hours divided into 7.5 hours of Oxic and 7.5 hours of Anoxic resulted in the most optimum percent removal.
