Activated carbon filtration for desalinated water

Published on by in Technology

Hello everybody

It is seen in some basic designs for potable water production plants, that activated carbon filtration has been considered on produced desalinated water along with remineralization.

Since desalinated water produced in both thermal and membrane systems is free from organics and other impurities, the question is if activated carbon filtration is basically required for the mentioned case.

Thank you and regards

    Basically, activated carbon is used to dechlorinate water from residual chlorine ahead of the RO membrane in addition to adsorp some organic matters.

     

    However, it should be known that backwashing the activated carbon filter should be based on the TOC in the filtered water rathar than to be on time basis since the media might be saturated with the organic material .

    This should be determined in the commissioning & operation period.
