WebThere is no single equation that can allow TOC to be calculated from BOD for all types of water/wastewater. Correlation is better for influent compared to effluent due to the effect of treatment. WebMar 22, 2024 · To predict effluent quality for a range of loadings, the influent and effluent soluble:total BOD5 ratio can be assumed to be 0.5. An alternative method of estimating soluble organic removal in the interstages, devised by E. J. Opatken (1986), utilizes a second-order reaction equation.
