Abstract
Description
O'jvit À i Dans le traitement des eaux de piscine, les particules solides sont captées à l'aide d'un filtre à sable ou à cartouche. Parmi les 1.5 million de piscines privées en France, environ 600.000 sont équipées d'un filtre à cartouche. Pour les jacuzzis et les spas la filtration à cartouche intégrée dans le circuit de circulation est standard. La cartouche de filtration a une finesse de filtration de 15 à 20 micromètres (pour un filtre à sable 40 à 50 micromètres). L'inconvénient d'un filtre à cartouche est son colmatage progressif. A cause de ce phénomène la pression avant la cartouche augmente et le débit de circulation diminue jusqu'à l'arrêt presque total. Dans ce cas la cartouche doit être remplacée. Le prix d'une cartouche de rechange (piscine familiale 4x8m) est entre 100 et 120 euros. Les fabricants de cartouches conseillent un nettoyage régulier avec un jet d'eau et les forums sur le web qui évoquent ce problème proposent d'essayer de l'eau de javel ou un produit anticalcaire, d'ailleurs toutes les deux sans résultat spectaculaire d'après ces forums. Dans un filtre à cartouche les grosses particules s'entassent sur le support et peuvent être enlevées par jet d'eau. Les particules avec un diamètre de plusieurs fois celui des pores du tissu filtrant se déposent aussi sur le support en formant une couche appelée `filter-cake'. Cette couche améliore, si elle est correctement formée, la finesse de la filtration et elle peut être aussi enlevée par jet d'eau. Les particules qui colmatent le filtre ont une taille presque identique à celle des pores du filtre. Le corps filtrant est composé de plusieurs couches de tissu superposées. Les pores de chaque couche individuelle par contre, ne sont pas superposés et forment un minuscule labyrinthe à travers le corps filtrant. C'est dans ce labyrinthe qu'elles se coincent. Sans intervention spécifique, le résultat final est un blocage total de la cartouche.In the treatment of pool water, solid particles are captured by sand or cartridge filters. Of the 1.5 million private swimming pools in France, around 600,000 are equipped with a cartridge filter. For Jacuzzis and spas cartridge filtration integrated into the circulation circuit is standard. The filter cartridge has a filtration fineness of 15 to 20 micrometers (for a 40-50 micron sand filter). The disadvantage of a cartridge filter is its progressive clogging. Because of this phenomenon, the pressure before the cartridge increases and the flow rate decreases until it stops almost completely. In this case the cartridge must be replaced. The price of a spare cartridge (family pool 4x8m) is between 100 and 120 euros. Cartridge manufacturers advise regular cleaning with a jet of water and the forums on the web that evoke this problem propose to try bleach or an anti-lime product, moreover both without spectacular result of after these forums. In a cartridge filter, large particles pile up on the substrate and can be removed by water jet. The particles with a diameter of several times that of the pores of the filter cloth are also deposited on the support forming a layer called filter-cake. This layer improves, if properly formed, the fineness of the filtration and it can also be removed by jet of water. The particles clogging the filter have a size almost identical to that of the pores of the filter. The filter body is composed of several layers of fabric superimposed. The pores of each individual layer, however, are not superimposed and form a tiny labyrinth through the filter body. It is in this labyrinth that they get stuck. Without specific intervention, the end result is a total blockage of the cartridge.
25 Dans ce cas elles ne peuvent plus être retirées par jet d'eau. La composition des impuretés donne la réponse au problème. Sauf d'éventuelles poussières amenées par le vent, elles sont toutes d'origine organique : humaine, végétaux et insectes décomposés, huiles, crèmes. Afin de pouvoir enlever ces matières, il faut donc l'action concertée de zéolites, agents de surface, enzymes ainsi que des éventuels 30 adjuvants qui agissent sur la qualité, la performance , la stabilité, le pH, l'alcalinité, l'aspect, de ces produits. Un lavage d'une cartouche colmatée, par submersion dans de l'eau tiède contenant 2 à 4% d'un tel produit pendant 12 à 48 heures (selon état), nettoie cette cartouche en profondeur. Ce procédé s'applique également aux cartouches utilisées dans la purification d'air. In this case they can no longer be removed by water jet. The composition of the impurities gives the answer to the problem. Except for any dust brought by the wind, they are all of organic origin: human, plants and decomposed insects, oils, creams. In order to be able to remove these materials, the concerted action of zeolites, surfactants, enzymes as well as any adjuvants which affect the quality, performance, stability, pH, alkalinity, of these products. A washing of a sealed cartridge, by submersion in warm water containing 2 to 4% of such a product for 12 to 48 hours (depending on state), cleans this cartridge in depth. This process also applies to cartridges used in air purification.
