Laboratory methods commonly used today are biochemical oxygen demand. chemical oxygen demand, and total organic carbon. Establishment of constant relationships among the various measures of organic content depends primarily on the nature of the wastewater and its source. Of al1 the measures, the most difficult to correlate to the others is the BODs test. because of the problems associated with biological tests The results were summarized as follwos , 1. For typical municipal wastes, however, the SBODs / SCODcr ratio varies from 0.14 to 0.34(mean 0.21). SBODs / STOC ratio varies from 0.35 to 1.19(mean 0.69) 2. Correlation analysis between the SBODs and SCODcr gave good correlation coefficient r = 0.903 and the equation Y = 3.756X + 16,221 was obtained 3. The correlation between the SBOD5 and STOC was well presented with equation Y = l ,070X + 7,637, and also correlation coefficient r = 0.821 4. The correlation between the SCOD , and STOC was well presented with equation Y = 0.256X+5.513 and also correlation coefficient r = 0.816 5. Becaus안 of the rapidity with which the TOC test can be conducted‘ it is anticipated that more use will be made of these tests in the future
