Modeling natural attenuation of chlorinated ethenes under spatially varying redox conditions.

abstract：:In biological nitrogen removal, application of the autotrophic anammox process is gaining ground worldwide. Although this field has been widely researched in last years, some aspects as the accelerating effect of putative intermediates (mainly N₂H₄ and NH₂OH) need more specific investigation. In the current study, exp...
