    Uso de Aditivos Poliméricos em Estações de Tratamento de Água (ETA) Substituindo os Compostos de Alumínio
    (Instituto de Tecnologia, 2015) BARBOSA, Cleyton Luiz Ramos; SOUZA, José Antonio da Silva
    The research explored the replacement of aluminum sulfate with polymeric additives (tannin and sodium polyacrylate) in water treatment plants (WTTPs). The study compared the technical efficiency and economic feasibility of these coagulants through Jar Test experiments, analyzing parameters such as pH, color, and turbidity. Results indicated that tannin outperformed aluminum sulfate in impurity removal, meeting potability standards, despite higher initial costs. The reduced sludge generation with tannin suggests long-term environmental and economic benefits.
