How can I modify the surface of polymer carriers for moving bed biofilm reactor (MBBR) in order to enhance their hydrophilicity performances.
Thank you.
Chingyeh - I think you can start to imagine really exotic surface chemistries (for example, grafting PEG or other hydrophilic polymer on the surface). My advice would depend on what you're trying to do. If it's very small scale, where the cost of the chemistry is no prohibitive, then either PEG or possible poly-lysine would be a way to go. There are many commercially available polymers using linkers such as NHS assuming you have a working group on the polymer to attack. If it's on a larger scale (where square meters of material might be required) I think I would look for much easier ways of making the surface more biofilm friendly. For example, just increasing the surface roughness by sanding or otherwise etching might produce a very readily colonized surface while not spending much money.
Good luck!

If its polymer has reactive groups in its structure, You can make a chemistry modification of this polymer by using hydrophilic polymer or make a grafting of hidrofilic compounds.

1. surface roughness
2. hydrophilicity
3. surface charge
are the factors that influence biofilm formation.
find out the type of bacteria present in the waste water and do functionalization accordingly.
All the best! post your updates!! i am interested. :)
