The theme is about mass transfer by filtration through a fixed bed. The most appropriate graph is: concentration versus time. The optimization of the operating system is obtained through a porous bed without high pressure losses, but also that it has a good flow velocity, because if we increase the speed too much, we lose in the capacity to remove the metal. Other important variables in the process are pH, adsorbent type and temperature. Therefore, it is necessary to perform a statistical response surface study to optimize the removal process.
