Performance Study of Basaveshwar Teaching and General Hospital Wastewater Treatment Plant at Kalaburgi

In this paper a Sequencing Batch Reactor (SBR) equipped for treating the hospital wastewaters has been studied in order to evaluate the removal of organic matter and other nutrients. The main goal was to examine the performance efficiency of the SBR used to treat hospital wastewater. Process efficiency was evaluated in terms of TS, BOD, COD, NO3-N, Sulphate and Chloride removal. The treatment plant located at the Basaveshwar Teaching and General Hospital Kalaburgi, India. The performance of Treatment Plant for biological nutrient removal was evaluated during 24 sample (06/10/2015 to 26/12/2015) of operation. The influent TS, BOD, COD, NO3-N, Sulphate and Chloride averaged at 680, 290, 435, 10, 43 and 122 mg/l respectively. The final treated effluent TS, BOD, COD, NO3-N, Sulphate and Chloride for the same period averaged 112, 20, 55, 42, 13.17 and 24.5 mg/l respectively. The operating results of the SBR process is both effective and efficient in meeting the water discharge and reuse quality requirements at the hospital. The SBR showed a high TS, BOD and COD removal. The removal efficiencies were high from the start of operation with TS, BOD and COD removal efficiencies of 82± 3% and 92 ± 2% and 86±3% respectively. The adoption of such approach resulted in: (1) Protecting the environment from pollution caused by the improper wastewater disposals, mitigating and reducing of the environmental and health problems and risks; (2) Providing a better management of the wastewater resources by reusing the treated wastewater for gardening purposes (3) Protecting the surface and ground water resources.
