ELIMINACIÓN DEL ACIDO ISOCIANÚRICO PRESENTE EN EL AGUA DE LAS PISCINAS

Abstract

The chloration is the treatment used disinfectant in swimming pools. The objective of the chloration is guarantee to the water a good "state of health" and to maintain the presence of a certain active free chlorine level to act such like oxidant-disinfectant against the contamination. When using chlorinated products for the disinfection of the swimming pool water the effect of the solar action is due to consider on chlorine. The ultra-violet rays transform chlorine into ion inactive chloride, which makes difficult to outdoors maintain a correct concentration of chlorine in swimming pools and times of strong insolation. The use of stabilizers of chlorine like the isocyanuric acid, eliminates this difficulty. If the isocyanuric acid is not used, in a sunny day, 90% of active chlorine it could destroy by the action of the sun, in two hours, this is a great problem considering the amount of radiation from the sun to which a swimming pool is exposed in summer. The isocyanuric acid is accumulated after weeks of treatment and the excess in the water can be prejudicial for the health, besides to prevent that the hypochlorous acid acts effectively on the microorganisms. This motivates the search of viable alternatives, as much technological as economically to the purification system, since numerous disadvantages of health consider, environmental and of maintenance.
