Resumo
A mucilagem e o pó de quiabo foram avaliados como biofloculantes no tratamento de água, utilizando o teste jar. Os conjuntos de agitação, os métodos de preparação do quiabo e a quantidade de coagulante / biofloculante foram avaliados na redução da turbidez. Os resultados mostraram que as agitações de 150 rpm e após 40 rpm foram mais eficazes na redução da turbidez. Os resultados mostraram que, quando se utilizou 80 mg / l de coagulante, foi observada uma remoção de 39% de turbidez e a adição de mucilagem e pó de quiabo foi de 76% e 88%, respectivamente. Portanto, todos os resultados mostraram que o pó de quiabo apresenta uma melhor redução da turbidez no tratamento da água. Ele pode ser preparado por metodologia simples e também permite a redução do coagulante em aproximadamente 64%. No pó de quiabo foram identificados grupos hidroxila que servem como locais ativos para a eliminação de partículas coloidais.
