Description
Método y dispositivo para la eliminación parcial del ácido isocianúrico en el agua de piscinas.Method and device for partial disposal of isocyanuric acid in pool water.
El objeto principal de la presente invención se refiere a un método y a un dispositivo que permite eliminar el ácido isocianúrico en el agua de las piscinas con el fin de conseguir un ahorro en el consumo de agua.The main object of the present invention is refers to a method and a device that allows the acid to be removed isocyanuric in the pool water in order to get a Water consumption savings.
El consumo de agua de red en piscinas se debe, principalmente, a las pérdidas por evaporación y a la acumulación de ciertas sustancias químicas.Network water consumption in swimming pools is due, mainly, the evaporation losses and the accumulation of Certain chemical substances
Dentro de este último factor, se encuentra el ácido isocianúrico (ICN). La concentración de ácido isocianúrico (ICN) acumulado en piscinas, como consecuencia de la desinfección del agua mediante derivados organoclorados, no se puede eliminar mediante un tratamiento físico-químico convencional. Por ello, los distintos reglamentos higiénico-sanitarios de cada provincia exigen realizar una purga y renovación diaria del agua del vaso, que suele estar en torno a un 5% del volumen total de la piscina, cantidad que en determinadas comunidades autónomas puede ser aún mayor.Within this last factor, is the isocyanuric acid (ICN). The concentration of isocyanuric acid (ICN) accumulated in swimming pools, as a result of disinfection of water by organochlorine derivatives, cannot be eliminated through a conventional physical-chemical treatment. Therefore, the different regulations hygienic-sanitary of each province demand perform a daily purge and renewal of the water in the glass, which usually be around 5% of the total volume of the pool, amount that in certain autonomous communities it may be even greater.
En el caso de una piscina olímpica, donde el volumen medio de agua es de 500 m^{3}, se estima un consumo diario de agua de red del orden de 10 m^{3}.In the case of an Olympic pool, where the Average volume of water is 500 m 3, daily consumption is estimated of mains water of the order of 10 m 3.
Cuando se emplean productos clorados para la desinfección del agua de piscina, se debe considerar el efecto de la acción solar sobre el cloro. Los rayos ultravioletas transforman el cloro en ión cloruro inactivo, lo que dificulta mantener una concentración correcta de cloro en piscinas descubiertas y en épocas de fuerte insolación. El uso de estabilizadores del cloro, tal como el ICN, elimina esta dificultad.When chlorinated products are used for pool water disinfection, the effect of the solar action on chlorine. The ultraviolet rays transform the chlorine in inactive chloride ion, which makes it difficult to maintain a correct concentration of chlorine in outdoor pools and in times of strong sunstroke. The use of chlorine stabilizers, such as the ICN eliminates this difficulty.
Comercialmente, el ICN se puede encontrar combinado con cloro formando compuestos organoclorados, tales como el ácido tricloroisocianúrico (C_{3}Cl_{3}N_{3}O_{3}) y el dicloroisocianurato sódico (C_{3}Cl_{2}N_{3}O_{3}Na) anhídrido o dihidratado. Estos productos de desinfección reaccionan en el agua formando ácido hipocloroso (HClO) e isocianúrico (C_{3}H_{3}N_{3}O_{3}):Commercially, the ICN can be found combined with chlorine forming organochlorine compounds, such as trichloroisocyanuric acid (C 3 Cl 3 N 3 O 3) and the sodium dichloroisocyanurate (C 3 Cl 2 N 3 O 3 Na) anhydride or dihydrate. These disinfection products react in water forming hypochlorous acid (HClO) and isocyanuric acid (C 3 H 3 N 3 O 3):
En resumen, el ICN se acumula al cabo de las semanas de tratamiento y el exceso en el agua puede ser perjudicial para la salud, además de impedir que dicho cloro actúe eficazmente. El nivel de ICN en piscinas debe mantenerse entre 25 y 75 mg/l y las asociaciones de salud pública recomiendan que la concentración nunca exceda de 100 mg/l. Para mantener o llevar el agua por debajo de este umbral, hay que purgar y renovar una parte de ésta, cada cierto tiempo.In summary, the ICN accumulates after weeks of treatment and excess in water can be harmful for health, in addition to preventing said chlorine from acting effectively. The level of ICN in swimming pools should be maintained between 25 and 75 mg / l and the public health associations recommend that concentration never exceed 100 mg / l. To keep or carry water below this threshold, you have to purge and renew a part of it, every certain weather.
El método que propone la presente invención permite eliminar parcialmente el ácido isocianúrico acumulado en el agua de piscina, con el fin de conseguir un ahorro en el consumo de agua de red. En el presente documento, el término "piscina" incluye tanto piscinas como cualquier otro tipo de aguas lúdicas que requieran la eliminación del ácido isocianúrico.The method proposed by the present invention allows partially isolate the accumulated isocyanuric acid in the pool water, in order to achieve savings in the consumption of mains water In this document, the term "pool" It includes both swimming pools and any other type of recreational waters that require the removal of isocyanuric acid.
El método consiste en la eliminación del ICN mediante la dosificación de un reactivo sólido (en polvo o en forma de comprimido) en base a la sustancia melamina (C3H6N6). La melamina reacciona con el ICN de forma cuantitativa, repetitiva y reproducible formando un complejo no soluble fácilmente eliminable por filtración.The method consists in the elimination of the ICN by dosing a solid reagent (powder or form of tablet) based on the substance melamine (C3H6N6). Melamine reacts with the ICN in a quantitative, repetitive and reproducible forming an easily soluble non-soluble complex by filtration
La melamina se disuelve con el agua de la piscina mediante un dispositivo de flujo y caudal controlados que permiten la óptima aditivación del reactivo en función de las características de cada instalación y del ICN a eliminar.Melamine dissolves with the water in the pool through a controlled flow and flow device that allow the optimum reagent additive based on the characteristics of each installation and the ICN to be removed.
El dispositivo va instalado en el propio sistema de filtración-depuración de la piscina y está compuesto por un laminador o enderezador de flujo, un dosificador donde se coloca el reactivo (en polvo o comprimido) y es donde se produce la aditivación por disolución y un mezclador estático que origina una turbulencia para favorecer la formación del complejo melamina-ICN. Posteriormente el complejo melamina-ICN es eliminado al quedar atrapado en un filtro, normalmente un filtro de arena de la instalación de filtración del agua de la piscina.The device is installed on the system itself pool filtration-purification and is composed of a laminator or flow straightener, a dispenser where the reagent (powder or tablet) is placed and is where produces dissolution additivation and a static mixer that originates a turbulence to favor the formation of the complex melamine-ICN. Subsequently the complex melamine-ICN is eliminated by being trapped in a filter, usually a sand filter from the installation of pool water filtration.
De esta forma se asegura que el agua retorna a la piscina sin exceso de ácido isocianúrico, disminuyendo así considerablemente la frecuencia de purgas de agua con el consiguiente ahorro de este recurso en las instalaciones.This ensures that the water returns to the pool without excess isocyanuric acid, thus decreasing considerably the frequency of water purges with the consequent saving of this resource in the facilities.
