Abstract

La invención se refiere a tratar el efluente primario de una fábrica de pulpa, papel o tableros contrachapados en una planta de tratamiento de aguas residuales introduciendo gas de escape que comprende dióxido de carbono (CO2) en el efluente primario que comprende calcio (Ca2+) y haciendo reaccionar el dióxido de carbono (CO2) con el calcio presente en el efluente primario para formar carbonato de calcio (CaCO3).The invention relates to treating the primary effluent of a pulp, paper or plywood board in a wastewater treatment plant by introducing exhaust gas comprising carbon dioxide (CO2) into the primary effluent comprising calcium (Ca2 +) and by reacting the carbon dioxide (CO2) with the calcium present in the primary effluent to form calcium carbonate (CaCO3).
