Abstract

Procedimiento para el pretratamiento de agua de mar destinada a desalación por ósmosis inversa. El procedimiento comprende: (a) captar agua de mar mediante toma abierta; (b) añadir permanganato potásico, en el punto de captación del agua de mar, en una cantidad adecuada para eliminar o reducir sustancialmente la materia orgánica y la materia viva presente en el agua de mar bruta captada; (c) neutralizar el exceso de permanganato potásico con un reductor adecuado antes de que el agua de mar entre en los filtros de arena; y, si fuera necesario, (d) ajustar el pH del agua de mar tratada con permanganato potásico y el reductor, procedente de los filtros de arena, a aproximadamente 7, antes de que entre en los filtros de afino. El agua así pretratada tiene un valor de SDI muy inferior a 4 (ASTM D-4189-82) y es adecuada como alimentación de la línea de producción de agua desalada mediante ósmosis inversa.Procedure for the pretreatment of seawater intended for desalination by reverse osmosis. The procedure comprises: (a) capturing seawater by open tapping; (b) add potassium permanganate, at the point of capture of seawater, in an amount suitable to eliminate or substantially reduce the organic matter and living matter present in the raw seawater collected; (c) neutralize excess potassium permanganate with a suitable reducer before seawater enters the sand filters; and, if necessary, (d) adjust the pH of the seawater treated with potassium permanganate and the reductant, coming from the sand filters, to approximately 7, before it enters the refining filters. Water so pretreated has a value of SDI much lower than 4 (ASTM D-4189-82) and is suitable for feeding the desalinated water production line by reverse osmosis.
