Abstract

decomposição de estruvita. trata-se de um método para decompor estruvita que compreende a dissolução (s10) de um material de alimentação que compreende estruvita em um ácido mineral. assim, uma solução que tem um ph ácido é formada. magnésio é removido (s30) da solução. a remoção de magnésio compreende aumentar (s32) um ph da solução até um ph na faixa de 4,5 a 6, precipitar (s34) compostos de magnésio que não compreendem amônio e separar (s36) os compostos de magnésio precipitados da solução. assim, a solução, após a remoção de magnésio, compreende um sal de amônio do ácido mineral. uma disposição para realizar tal método é também divulgada. além disso, são divulgados um método e uma disposição para recuperar pelo menos nitrogênio do material de refugo, com base na decomposição de estruvita.
