How bod is measured
WebBOD (or COD) load: Units: kg/day The concentration of BOD (in mg/l) in the influent can be used to calculate the total BOD load per day being treated. This is simply done by multiplying the BOD in mg/l by the daily effluent volume in cubic metres (m3) and dividing the product by 1000. WebThe chart below is intended to be a guide in selecting dilution amounts. It presumes a SCF value of 0.8. Each column is for an amount of oxygen depleted and each row is for a volume of sample in the bottle. Chart 1: BOD value in mg/L for various sample volumes and depletion amounts. DO Depletion.
