Bio carriers in the activated sludge process: improves the organic removal rate,
can be used for the elimination of COD and BOD as well as for nitrification and denitrification.
can be efficiently used for significantly increasing the capacity of existing activated sludge sewage treatment plants without any need for structural changes.
so, is it possible to use them in anaerobic conditions?

Interesting topic. I googled a bit and found a paper. Check it out.

Hi, bio-carriers can be applied in anaerobic, anoxic and aerobic conditions. They act as a support media where microorganisms from different conditions attaching on them from outer surface area and internal surface area. There are many journals you can find via Science Direct. Thank you.
Dear Gopi, As already confirmed by others, the answer to your 2 questions is positive ("Yes"). However the assumption that biocarriers would "significantly increase the capacity of existing activated sludge (AS) systems" is not substantiated in spite of the wild claims of the suppliers of commercial carriers. In real world large scale AS systems retrofitted with biocarriers (called IFAS) we found no improvements at all in treatment performance nor capacity. In fact there was very little biofilm on the biocarriers (less than 10% of the biocarriers in terms of mass as dry solids). Since about 25 years we boost the performance and capacity of new and existing AS systems within the same basins by biosorption combined with kinetic and metabolic selection resulting in highly active and dense biosludge enabling up to 10 g/l MLVSS which is 3 - 4 times higher than most AS systems.
Dear Ms. G Tejaswari .. we come to the subject of remediation on P.C B matter. Certainly caution is to be afforded prior usage of processed water. If re use water used for flush water.. can be appplied. For lawns and parks. Can be used... However for itrigation for agri farms.more assessment is desired. Apply UV as post process on trickle flow.. Bio carrier behave similar to phyto r.. and can be applied for many variations of pollutants.. we offer our well wishes for progress of researching on bio carriers. Ajit Seshsdri
.
we use bio carriers for denitrification in anoxic conditions and it is working great!
Good luck
