Abstract
resumo adição de reagentes de alumínio a um fluxo de resíduos contendo sulfato reduz a concentração de sulfato a invenção proporciona métodos e composições para a detecção e a remoção de sulfatos a partir de um líquido. o método proporciona uma remoção mais rápida do sulfato do que a arte anterior e faz o mesmo enquanto requer o uso de menos alumínio. o método envolve adicionar sequencialmente um acídico para um agente de alumínio gerando um ph neutro ao líquido, um agente de alumínio gerando um ph alcalino ao líquido, após ter adicionado um acídico ao agente de alumínio gerando um ph neutro e um agente de cálcio alcalino ao líquido. a taxa mais eficiente possível pode ser obtida também usando um fluoróforo para determinar precisamente a quantidade de sulfato no líquido.
