Pengaruh Variasi Konsentrasi Limbah Cair Tahu Terhadap Penyisihan Cod Dan Nh3 Menggunakan Rotary Algae Biofilm Reactor (Rabr)

---

Tofu industry in Indonesia, which is dominated by household-scale businesses, has limited fund to process the tofu liquid waste produced therefore it is disposed directly into water bodies without appropriate treatment. Tofu liquid waste has a status that is not feasible to discharge into water bodies because it can pollute the aquatic environment due to its content consisting of organic compounds and high nutrients. Utilization of tofu liquid waste as a source of nutrients to support the growth of microorganisms such as microalgae Chlorella sp. can be an alternative to the problem of tofu liquid waste using Rotary Algae Biofilm Reactor (RABR) technology. This study aims to determine the growth rate of microalgae and the removal of COD and NH3 parameters by cultivating Chlorella sp on a medium with various treatments of tofu liquid waste concentration, namely 40%, 60%, 80% and 100% and contact time (0, 1, 3, 5 day). The results showed that in the treatment of 40% tofu wastewater concentration on day 5, the highest COD and NH3 removal efficiency were 75,88% and 80,45%, respectively, with the total density of suspended and attached cells of Chlorella sp. of 3,99 x 106 cells/ml.
