Abstract

controle da atividade bacteriana, tal como em esgotos e sistemas de tratamento de águas residuais. a presente invenção refere-se a um método para o controle da atividade das bactérias redutoras de sulfato ou da arqueias metanogênicas (ou ambas) em ambientes contendo tais organismos compreendendo o tratamento do ambiente com ácido nitroso livre (hno~ 2~) ou com uma solução contendo nitrito (no~ 2~) tendo um ph menor do que 7 ou mediante a adição de nitrito ao ambiente e tendo um ph menor do que 7 no ambiente. o método também pode romper as biopelículas.
