Abstract

Analysis of the levels of chemical oxygen demand (COD) in wastewater hospitals using closed reflux titrimetric method. Has done heating samples of hospital waste that passes through the refineries for 2 hours at a temperature of 148 ° C in COD Thermoreactor obtained that level of COD in waste water that is the first week of 52.33 mg / L, the second week of 63.62 mg / L, the third week 68.42 mg / L, the fourth week of 58.43 mg / L and the fifth week of 46.54 mg / L. From the results obtained show that the hospital waste water does not exceed the maximum standards set by KEP-58 / MENLH / 12/1995 concerning water quality standards of hospital waste
