Abstract

Se divulga un método para producir un producto que comprende fósforo, donde el método comprende obtener un efluente o filtrado a partir de un proceso de fabricación de pasta química; ajustar el pH de al menos una parte del efluente o filtrado a alcalino con un agente alca-lino; permitir que el fósforo se preci-pite en la forma de sal de fosfato y se-parar el precipitado para producir un efluente o filtrado purificado y un re-siduo que comprende el precipitado. Ade-más, se describen un producto que se puede obtener mediante el método y el uso del producto.A method for producing a product comprising phosphorus is disclosed, where the method comprises obtaining an effluent or filtrate from a chemical pulp manufacturing process; adjust the pH of at least a part of the effluent or filtered to alkaline with an alkaline agent; allow the phosphorus to precipitate in the form of phosphate salt and separate the precipitate to produce a purified effluent or filtrate and a residue comprising the precipitate. In addition, a product that can be obtained by the method and use of the product is described.
