Abstract
Procedimiento de remineralización de fluidos.#La presente invención se refiere a un procedimiento de remineralización de fluidos con control de la turbidez final. Dicho procedimiento comprende las etapas de dosificación de reactivos, remineralización y filtración. Más específicamente, la invención se refiere al tratamiento de agua para consumo humano, procesos industriales, uso agrícola u otros usos que requieran ajuste de parámetros de dureza, alcalinidad, pH, índice de saturación de Langelier (LSI), etc.Fluid remineralization procedure # The present invention relates to a fluid remineralization procedure with final turbidity control. Said process comprises the steps of reagent dosing, remineralization and filtration. More specifically, the invention relates to the treatment of water for human consumption, industrial processes, agricultural use or other uses that require adjustment of parameters of hardness, alkalinity, pH, Langelier saturation index (LSI), etc.
