| Summary: | As Dr. H. A. Rotinsulu Lung Hospital plans to develop its health services and facilities for 20 years ahead, it will be followed by the increment of the production of wastewater. The existing wastewater treatment plant (WWTP) has the capacity to serve 130 beds or about 80 m3/day however the projected wastewater production for 20 years is 170 m3/day. A new WWTP is to be designed due to the change of the sanitary piping system from each building to the WWTP. Other problems towards the existing WWTP is that it does not yet encourage the removal of micro pollutants and it is urged by The Republic of Indonesia Health Ministry to imply the concept of green hospital. The main parameters of focus are BOD, COD, TSS, oil and grease, and coliform bacteria with the concentration of 200 mg/L, 400 mg/L, 300 mg/L, 40 mg/L, and 1,5x106 MPN/100 ml respectively. Suggested alternative technologies for treating the hospital wastewater are Completely Mix Activated Sludge (CMAS), Rotating Biological Contactor (RBC), and Membrane Bioreactor (MBR). Selection of the best alternative is based on comparing calculation results of each alternative and finding the most suitable result to the selection criteria which includes the operational, technical, environmental, and economical aspects. From this analysis, MBR is the most suitable technology. The new designed WWTP system consists of a bar screen, equalization tank, and primary clarifier as the primary treatment, MBR for the secondary treatment, and sludge treatment by gravity thickener and sludge drying bed. The total investment for this WWTP is Rp 2.059.281.364 with an annual operation and maintenance cost of Rp 1.010.322.739. |
