ANAMMOX

Hi all,
Please I am using WEST to simulate ANAMMOX process, and this is my first time to try it with WEST. Please can someone guide me on how to go about it? I am using WEST2011

Thanks in advance!

The "conversion model" for [b]ANAMMOX [/b]was first included in WEST in [b]release 2012[/b].
I am afraid your only option is to implement it yourself through the Model Editor.

Thank you very much, Enrico. Could you offer some guide on the implementation? Or could anyone who have also implemented it before offer some guide? Thanks a lot.

The ANAMMOX model that is implemented in WEST (as of release 2012) derives from ASM1:
[list]
[li]S_NO is split into S_NO2 and S_NO3[/li]
[li]X_BA is split into X_NH, X_NO with the specific X_AN (the ANAMMOX biomass)[/li]
[/list]
The processes included in the conversion model are:
[list]
[li]Hydrolysis[/li]
[li]Aerobic growth of heterotrophs[/li]
[li]Decay of heterotrophic biomass[/li]
[li]Anoxic growth of heterotrophs by reducing nitrate to nitrite[/li]
[li]Anoxic growth of heterotrophs by reducing nitrite to nitrogen gas[/li]
[li]Aerobic growth of ammonium oxidisers (AOB)[/li]
[li]Decay of ammonium oxidisers[/li]
[li]Aerobic growth of nitrite oxidisers (NOB)[/li]
[li]Decay of nitrite oxidisers[/li]
[li]Anaerobic growth of Anammox biomass[/li]
[li]Decay of Anammox biomass[/li]
[li]Aeration[/li]
[/list]

This would in principle enable you to [b]create the Gujer Matrix for the new category[/b].
But the details of the conversion model, i.e. stoichiometry and kinetic expressions, as well as some interactions with the rest of the library, are difficult to explain here.

Thank you very much, Enrico.
