Ammonia inhibition

Hi all,

I need your help /suggestion please respond.

In anaerobic digestion model ammonia inhibition as low as 12% (very bad). Soluble concentration of acetate in the effluent is very high when compare with others. I think the ammonia inhibits uptake of acetate and reduces the acetate degradation. How I overcome this problem? 

Thanks

I would also assume this is the reason why acetate does not get degraded.
Is it only the ammonia inhibition factor that affects the acetate uptake? I mean: are all the other inhibition and 'Monod' terms inactive, i.e. ~1 ?
You need to backtrack the source of such high ammonia inhibition (low inhibition term) and potentially of the other terms negatively affecting acetate uptake.

Thanks for your replay Enricho.

All other inhibition terms are close to 1. pH is 7.3.  I couldn't verify other factors which affet the acetate degradation except ammonia inhibition. Do you have any other suggestions?

thanks

Based on the elements provided here, no, I cannot think of anything else.
