C-Sys: COD COD is a measure of the organic load
in a substance and, is therefore important as a measure of pollution,
quantifying organic product loss and calculating effluent charges.
CSys_COD measures COD by a standard method using acidic oxidation
with Dichromate ions.
It should also
be noted that with this method, Aromatics and pyridines are not
oxidised at all. In natural waters these interferants are rare,
but care must be taken with industrial liquors. Sample must be pretreated
to avoid blockage, this may be achieved with a cutter pump and a
crossflow filter. Soluble COD may be determined using a submersible
ultrafilter
