The BOD test relies on the measurable depletion of DO around a specified time period. Mainly because most samples of wastewater can have a BOD increased that the quantity of oxygen available inside the BOD bottle in the course of the incubation period of time, the samples must be diluted. This dilution is done by adding dilution water towards the sample inside the BOD bottle.
The Winkler System takes advantage of titration to determine dissolved oxygen in the h2o sample. A sample bottle is stuffed entirely with water (no air is still left to skew the outcomes). The dissolved oxygen within the sample is then "fixed" by incorporating a series of reagents that variety an acid compound that is definitely then titrated by using a neutralizing compound that results in a shade modify.
Be aware: If This can be the case, a notation must be built about the sample bench sheet that potentially invalid info has long been utilised to ascertain the noted worth. Sample dilution volumes must be cautiously selected making sure that at least one particular dilution satisfies both of those criteria.
