COD and BOD removal
There are different options for Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) removal:
- A first option is biological purification where the polluting components are removed by means of bacteria.
- Sometimes, an alternative is the use of ultrafiltration to separate the polluting components.
- The third option is treatment through an active carbon filter. In this technique the polluting components are adsorbed. This is only an interesting option in case of low concentrations.
PCA can help you with this technology, both in design and construction of the installation.
