COD is most fitted for rapid and frequent checking of remedy plant effectiveness and h2o good quality.
There's a correlation in between COD and BOD, on the other hand, it should be experimentally established ahead of applying 1 parameter to specific A further. Typically COD Assessment (that is a considerably faster and even more correct system) is utilized to estimate BOD utilizing the established correlation.
Substantial COD concentrations in wastewater show the existence of organic and natural substances that could decrease the level of dissolved oxygen.
There are plenty of ways that have been proven to reduce COD in the management of wastewater. Wastewater Separation (coagulation and flocculation) and COD removal by microbial action are two of the most common strategies to remove COD in wastewater.
