Abstract

"MéTODO E APARELHO PARA O TRATAMENTO DE áGUA RESIDUAL REDUZINDO A CONTAMINAçãO BACTERIANA DA MESMA". Método e aparelho para seq³encialmente dosar água residual com um desinfetante em uma pluralidade de locais espaçados ao longo de um percurso de fluxo (15), tal como em um tanque de contato (10). As dosagens de desinfetante introduzidas em cada local são colocadas em proporção ou graduadas, de modo que a dosagem em cada local seja menor do que as dosagens enviadas a montante dali. A dosagem graduada provê um nível de desinfetante efetivo para destruir ou, de outra forma, tornar inofensivos microorganismos na água residual e minimizar o desinfetante residual remanescente no final do percurso de fluxo, enquanto se emprega uma quantidade total menor de desinfetante, em comparação com as técnicas de dosagem única convencionais.
