Abstract
Método para reducir el fósforo en efluentes y aguas del proceso en una fábrica de pulpa o una fábri ca de papel, que comprende: - ajustar el pH del agua a tratar mediante un agente alcalino (A), - suministrar iones de carbonato al agua, - precipitar carbonato de calcio a partir del agua a tratar por efecto de los iones de carbonato suministrado s al agua, - coprecipitar el fósforo junto con el carbonato de calcio precipitado y - separar el fósforo coprecipitado del efluente o el agua del proceso junto con el carbonato de calcio precipitado.Method for reducing phosphorus in effluents and process waters in a pulp mill or paper mill, comprising: - adjusting the pH of the water to be treated by an alkaline agent (A), - supplying carbonate ions to the water, - precipitate calcium carbonate from the water to be treated by the effect of carbonate ions supplied to the water, - co-precipitate the phosphorus together with the precipitated calcium carbonate and - separate the co-precipitated phosphorus from the effluent or the process water together with the precipitated calcium carbonate.
