The quantity of suspended sediment passing some extent in the stream more than a specified stretch of time. When expressed in tons a day, it really is computed by multiplying water discharge (in cubic feet for every next) from the suspended-sediment concentration (in milligrams for every liter) and because of the issue 0.0027.

Dr Kani is proper. Attached is actually a web site from the Masters thesis which shows the relationship of measured values of BOD and COD. Observe the BOD benefit is close to zero if the COD worth is close to 50 Considering that the BOD demonstrates only the dissolved organics though COD includes whole dissolved organic and inorganic compounds.
