Abstract: The coffee processing industry is one of the major agro-based industries contributing significantly to the India’s national income. Coffee fruits are processed by two methods viz., wet and dry process. In wet processing, coffee fruits generate enormous quantities of high strength wastewater requiring systematic treatment prior to disposal. The present study is attempts to assess the efficiency of batch aeration as post treatment of coffee processing waste water from a UAHR by continuous and intermittent aeration system. Results showed that the maximum BOD, COD and TS removal efficiency of 74.5 %, 68.6 % and 49.3 %, respectively were recorded in biomethanated CPWW aerated continuously. The finding of the study indicated the efficiency of batch aeration in treating wastewater as post treatment of previously treated coffee processing wastewater by the Upflow Anaerobic Hybrid Reactor (UAHR).
