Efficiency Analysis of CBA Full-scale Hospital Waste Water Treatments in Indonesia Using Combined Biological AOP System: Investigation on Operating Conditions, Treatment Efficiency and Energy
Abstract
Combined biological AOP system, or CBA, are increasingly being used in Indonesia to treatment hospital waste water, that are otherwise difficult to treatment in conventional methods. CBA catalytic ozonation are now used for over 579 hospitals, making this tool a major phenomenon for high adopt hospital waste water treatments in Indonesia, and one that has experienced great expansion over the past three years. The question of whether the CBA is a good or a bad tool for the treatment hospital waste water depends on many parameters. To respond to this question, it is necessary to investigate on operating conditions, but it is also very important to gather more data and conduct further research on treatment efficiency and energy. In this paper, we examined and discuss to gain a better understanding of the CBA environmental technology and of its impacts. About 100 CBA Full-scale Hospital waste water treatments have been investigated, and it was in Indonesia from eight provinces. CBA demonstrate good removal efficiency of macro-pollutants from hospital waste water and meet the requirements as per LH R.I. Number 5 Year 2014 on Wastewater Quality Standard and LHK R.I. Number P.68 / Menlhk / Setjen / Kum.1 / 8/2016 Concerning the Quality Standards of Domestic Waste Water. Various parameters of macro-pollutants such as pH, temperature, TDS, TSS, BOD 5, COD, oil fat, and MBAS also amonia nitrogen and total coliform were analysed to identify the performance of CBA. We obtained the average energy consumption per cycle is 0.504 kWh, capacity V m3/hours which treatment cost Rp 1.478/m3 and 60,96%-94,00% removal efficiency of macro-pollutants. CBA catalytic ozonation reported here is very efficient and environmental friendly for treatment hospital waste water.
