Abstract
Description
La présente invention concerne un procédé de filtration de l'eau de mer au moyen d'un granulat minéral expansé synthétique. The present invention relates to a process for filtering seawater using a synthetic expanded mineral aggregate.
I/ FABRICATION DU GRANULAT
Ce granulat doit être léger, poreux, permettre le passage de l'eau de mer en son sein, présenter une grande surface de contact avec l'eau, il ne doi entraîner aucune modification des constantes physico-chimiques naturelles de l'eau de mer, et doit être capable d'éliminer toutes les formes de pollution tendant à modifier ces normes physico-chimiques.I / MANUFACTURE OF AGGREGATE
This aggregate must be light, porous, allow the passage of sea water within it, have a large contact surface with water, it must not cause any modification of the natural physico-chemical constants of sea water. , and must be able to eliminate all forms of pollution tending to modify these physico-chemical standards.
Le granulat est obtenu par le concassage d'un bloc minéral expansé de synthèse fabriqué selon la formule
Nous utiliserons un mélange anhydre de
- une matière riche en acide silicique, comme par exemple du sable, finement broyé et tamisé (mailles du tamis 0,5 mm) 55 %
- un liant hydraulique comme par exemple du ciment 28 % ;;
- une matière basique cosse par exemple de la chaux vive broyée, tamisée (grains < 0,5 mm) 13 %
- une matière riche en carbone pur comme par exemple du charbon de bois broyé et tamisé (grains < 0,5 mm) 1,7 %
- une matière ayant des propriétés antiseptiques connues comme par exemple du sulfate de cuivre 0,1 %
- nous adjoindrons à ce mélange anhydre un métal susceptible, avec une solution basique, de réagir en produisant de l'hydrogène, gaz qui rendra poreux notre bloc minéral lors de sa prise en masse ainsi qu'un agent régulateur comme par~ exemple, de la poudre d'aluminium 0,2 %, et du sulfate de calcium 2 %.The aggregate is obtained by crushing an expanded synthetic mineral block manufactured according to the formula
We will use an anhydrous mixture of
- a material rich in silicic acid, such as for example sand, finely ground and sieved (mesh of the sieve 0.5 mm) 55%
- a hydraulic binder such as cement 28%;
- a basic pod material, for example crushed quicklime, sieved (grains <0.5 mm) 13%
- a material rich in pure carbon such as for example ground and sieved charcoal (grains <0.5 mm) 1.7%
- a material having known antiseptic properties, for example 0.1% copper sulphate
- we will add to this anhydrous mixture a metal capable, with a basic solution, of reacting by producing hydrogen, gas which will make porous our mineral block during its solidification as well as a regulating agent like for example, 0.2% aluminum powder, and 2% calcium sulfate.
Une fois notre mélange réalisé, et ses composants soigneusement mélangé, nous allons le mouiller avec une solution basique comme par exemple de la soude à la concentration obtenue en dissolvant 6 grammes de paillettes de soude caustique dans un litre d'eau. Once our mixture is made, and its components carefully mixed, we will wet it with a basic solution such as, for example, soda at the concentration obtained by dissolving 6 grams of flakes of caustic soda in a liter of water.
la mélange est mouillé avec la quantité de solution basique équivalent à 50 % du poids anhydre du mélange. the mixture is wetted with the amount of basic solution equivalent to 50% of the anhydrous weight of the mixture.
Le mélange mouillé est alors mis dans des moules que l'on place dans un autoclave à vapeur d'eau. Dans l'autoclave se produira l'expansion du produit, sa prise et son durcissement. The wet mixture is then placed in molds which are placed in a steam autoclave. In the autoclave, the product will expand, set and harden.
la bloc obtenu après refroidissement est placé dans un broyeur qui peut être à cylindre, et concassé de façon à obtenir un produit de granulométrie variant entre 2 et 5 mm, les déchets plus fins étant éliminés. the block obtained after cooling is placed in a crusher which may be a cylinder, and crushed so as to obtain a product with a particle size varying between 2 and 5 mm, the finer waste being eliminated.
IIZEXEMPLE D'UTILISATION DU GRANULAT EN AQUARIOPHILIE HARGNE
Nous utilserons pour cela une cassette verticale amovible(3) permettant le passage de 1 eau de haut en bas remplie de granulat.IIZAMPLE USE OF AGGREGATE IN AQUARIOPHILIE HARGNE
We will use for this a removable vertical cassette (3) allowing the passage of 1 water from top to bottom filled with aggregate.
La taille de la cassette et la quantité de granulat sont déterminés par la taille de l agu rium. The size of the cassette and the amount of aggregate are determined by the size of the agu rium.
Sur la cassette est adaptée une pompe(2) aspirante refoulante qui aspire l eau passée à travers le granulat et la refoule dans l'aquarium.La puissance de la pompe et son débit sont adaptés au volume d'eau a' filtrer. On the cassette is fitted a pressure suction pump (2) which sucks the water passed through the aggregate and discharges it back into the aquarium. The power of the pump and its flow rate are adapted to the volume of water to be filtered.
La cassette est placée dans un bâti vertical (1) formant fond de l aquarium et la rendant interchangeable
III/RESULTATS ET AVANTAGES OBTENUS AVEC LE GRANULANT
Le granulat mis en présence d'eau de mer est neutre vis a' vis des propriétés physico~chimiques normales de l eau.Il a une porosité macroscopique et microscopique permettant le passage de l'eau et retenant les impuretés physiques en suspension dans l'eau de mer sa porosité microscopique permettant lors de filtration longues en circuit fermé l'installation de bactéries qui éliminent les substances azotées dissoutes dans l'eau de mer.The cassette is placed in a vertical frame (1) forming the bottom of the aquarium and making it interchangeable
III / RESULTS AND BENEFITS OBTAINED WITH THE GRANULANT
The aggregate put in the presence of sea water is neutral with respect to the normal physico-chemical properties of water. It has a macroscopic and microscopic porosity allowing the passage of water and retaining the physical impurities suspended in it. seawater its microscopic porosity allowing during long filtration in closed circuit the installation of bacteria which eliminate nitrogenous substances dissolved in seawater.
Le granulat a des propriétés antiseptiques, absorbantes et des propriétés tampon maintenant le Ph de l'eau de mer à une valeur voisine de 8,3. The aggregate has antiseptic, absorbent and buffering properties keeping the pH of seawater at a value close to 8.3.
Lors de 1 utilisation du granulat comme masse filtrante dans un système de filtration de l'eau de mer ouvert ou fermé. When using the aggregate as a filter medium in an open or closed seawater filtration system.
nous obtenons un filtre unique qui réalise à lui seul toutes les fonctions de filtration que l'on peut exiger d'un filtre:
~f ltration physique
~filtration chimique
filtration biologique permettant au sein de la masse d'eau filtrée la pérennité de la vie marine.we obtain a single filter which alone achieves all the filtration functions that can be required of a filter:
~ physical filtration
~ chemical filtration
biological filtration allowing the sustainability of marine life within the filtered water body.
On atteint ainsi une simplification de la filtration en aquariophilie marine:
filtre unique aisement interchangeable
~inutilité de contrôler les constantes de l'eau
possibilite de montages esthétiques entiérement inclus dans l'aquariur. This simplifies filtration in marine aquariums:
easily interchangeable single filter
~ no need to check the water constants
possibility of aesthetic assemblies fully included in the aquariur.
On peut envisager toute application du granulat dans la filtration d un volume quelconque d'eau de mer. Any application of the aggregate can be envisaged in the filtration of any volume of sea water.
L'invention n'est pas limitée à l'exemple de réalisation représenté et décrit car diverses modifications peuvent y être apportées sans sortir de son cadre. The invention is not limited to the embodiment shown and described since various modifications can be made thereto without departing from its scope.
