Reuse of Phosphogypsum Water as a Strategy for Reducing Consumption and Improving Efficiency in Phosphoric Acid Production
ABOUT IT
The project consists of a new phosphorus recovery process from the phosphogypsum pile, with direct application in the agro-industry. The technology captures the accumulated effluent from rainwater regarding the phosphogypsum pile, which previously contaminated the drainage system with chemical compounds such as phosphorus and fluorine.
This water is reused in the production process, reintegrating the phosphorus (P₂O₅) to the system, increasing the efficiency of phosphoric acid production and transforming one environmental liability in productive resources. Studies on the chemical behavior of effluents and water balance simulations were carried out to make the solution viable.
