Description

OBJECT OF THE INVENTION

The present invention relates to a tablet for integral water treatment, based on being formed by three parts that dissolve according to phases of different periods of time, allowing a shock treatment with a contribution of functions and a maintenance of the water to be treated. in a lasting way.

The object of the invention is to achieve different water treatments with a single tablet.

The field of application of the tablet is intended for the treatment of water in swimming pools, spas, water parks, treatment plants, disinfection systems, fountains ~ artificial waterfalls, etc., that is, for the treatment of recreational and decorative waters.

BACKGROUND OF THE INVENTION

There are numerous types of tablets existing in the market for water treatment, being able to mention first the typical slow-dissolving tablets for a prolonged treatment of water, given its stability and controlled solubility, while secondly the multifunction tablets for swimming pools with algae problems, access of particles in the water, hardness problems, etc., comprising this second type of chlorinated derivative tablets that are mixed with other products for subsequent compaction. There are also fast-dissolving tablets, intended for hyperchlorination or rapid chlorination and to solve serious problems in the water quickly and effectively.

There are also stuffed products (tablets) with alternative functions such as mosquito repellents, metal metal sequestrants, etc., there being another alternative field to chlorinated products and which are the tablets based on active oxygen and others based on brominated compounds.

The problem presented by the numerous variety of pills is that the client does not finish getting the first choice to treat the water in the desired way. In other words, if you decide on one or the other pill, sometimes a specific and specific treatment is carried out, but a vacuum is left in relation to other treatments.

In any case, there are numerous patents of invention in which tablets for water treatment are described, first mentioning US Patent 3,873,685, where a process for manufacturing a tablet or a compound with a mixture is described of dichloroisocyanurates and trichloroisocyanurates, to obtain in the same product (patterned or not) a shock treatment and a subsequent action of lasting maintenance.

In US Patent 3,956,444 another method is described for making a quick dissolution tablet based on a dichloroisocyanuric derivative, offering a shock treatment for water.

A process for obtaining a fast dissolving pasture, based on tricoloroisocyanuric acid, is described in US Patent 4,389.318 as the most important technical active ingredient, the dissolution rate being lower than that of the previous dichloroisocyanuric acid. In this tablet it was possible to incorporate a bicarbonate that provides effervescence quickly. to disengage the tablet and therefore increase the contact surface of the tricolor isocyanuric grains and thereby increase their solubility.

In US Pat. No. 2004/0040915 A 1 a mixture with, at

less, a halogenated product as a disinfectant, as well as at least one

pH regulator Said pennite mixture obtain a pill for disinfection of water and control biosecurity, being specially applied to

Pools and spas.

In US patent 6,852,238 another tablet is described, in this case bilayer or double layer, where one of the layers is of slow dissolution based on coroisocyanuric or brominated products, and another fast dissolving layer based on dichloroisocyanuric . A pH regulating compensator is also incorporated in this tablet that helps maintain the pH.

In patent 2005/00400116 Al a double layer tablet is also described, that is to say a fast dissolving layer and another slow dissolving layer, which is multifunction, based on the products TeCA, lithium hypochlorite, calcium hypochlorite, sodium persulfate, potassium persulfate, potassium monopersulfate, dichloroisocyanuric, sodium anhydrous and, at the hands, a clarifier, an algaetic pH reducer, algicide, descaler, anticalcarea, flucolante, degreaser, dispersant, colorant, dissolution rate controller, fragrance, surfactant in the slow layer, and chlorinated compounds, or brominated in the fast dissolving layer.

In US Patent 7,018,562 B2 a manufacturing process of a fast dissolving tablet is described, with cyanuric acid, trichloroisocyanuric acid, anhydrous dichlorisocyanuric acid, magnesium sulfate and / or alumina sulfate and warm carbonate.

In the invention patent US 7,404,902 B2 a method is described for the treatment of water, in which, based on boric acid and cyanuric acid, a product is added that serves as a metal sequestrant and another as a clarifier.

In US patent 2009 / 0220.559 A 1 a solid multifunction formulation in bath pill is described, mixing a sanitizer, a bath disinfectant and a deodorizing substance.

Finally, in US Patent 7,534,368 B2 a tablet based on a halogen (bromide and / or chlorine) is described as biocides, together with other products that generate a gel layer when they come into contact with water, facilitating dissolution of the tablet and also in a prolonged way, since a gelatinous structure is created that contributes to the stability of the product.

In none of the cases a pill is obtained by means of which an integral water treatment can be carried out, but treatments are carried out to solve one or the other problems, but in no case of integral water.

DESCRIPTION OF THE INVENTION

The recommended tablet has been conceived to carry out an integral water treatment, based on a structure determined by three parts, one of rapid dissolution, another of slow dissolution and another of intermediate dissolution to provide different functions, as later on. will expose.

The tablet according to the invention will have a mark engraved on one of its faces to increase customer recognition and thereby allow clear differentiation from other conventional tablets.

Obviously the compaction to get the three layers of the tablet will be appropriate and its fan will be circular, since it is the fan that allows a better compaction, since edges or angles could lead to damage to the punches, matrices and beds of the own compaction machine.

More specifically, the tablet of the Invention will comprise three parts, two of them with the same diameter but different weight, and logically of different thickness, so that the first part, that is to say the thickest or tallest, is a slowly dissolving layer. intended to maintain the water under acceptable conditions, its trichloroisocyanuric acid, as well as active oxygen or brominated derivatives, being its fundamental active ingredient, acting as a disinfectant and allowing the addition of at least one anti-scale product or even a sequestering product of metals. It will also be accompanied by an adjuvant substance such as alkaline stearates (magnesium, calcium), talc, citric acid, etc. This layer may optionally have a dye.

The second layer, of the same diameter as the previous one, although of a lower weight and therefore of a lower height, is a fast dissolving layer and is used for shock treatment, hyperchlorination and acting against a serious problem of the water to be treated, by an example of a pool, so that this layer dissolves quickly, thanks to some of the components that disintegrate, increasing the surface in contact with water and therefore helping to dissolve it. The main active ingredient of this second layer can be ATCC (trichloroisocyanuric acid) or OCCna (Sodium salt of dichloroisocyanuric acid dihydrate), and disintegrants, dense sodium carbonate, and / or sodium bicarbonate and / or cyanuric acid, including also an adjuvant to favor the extraction of the compaction machine. Said second layer may also carry a dye.

The third layer is an independent element, of smaller diameter and of less weight, being the part that adds most of the auxiliary functions such as algaecides, algistatic, flocculants, descalers, degreasers, pH regulators and also including a binder, so that said third layer confers an independent element that is obtained in another machine, subsequently incorporating into the body that the two layers referred to above refer.

The third layer may also include a dye and will be housed in the second layer, that is to say the lower one, being embedded in a hole or cavity thereof in part of the height.

The particularity of the tablet obtained pennite that if the water to be treated does not require the third layer with auxiliary functions, that independent element is easily removable by the user, thus avoiding providing substances that are not needed, thus respecting the environment ambient.

In any case, the most outstanding advantages obtained through the tablet of the invention can be summarized in the following:

It is a unique product for the integral treatment of the water of a swimming pool, spas, or decorative or recreational water. It has a high concentration and stability of the fundamental disinfectant, increasing its storage capacity over time and reducing the risk in it. It offers excellent compaction for obtaining a desired dissolution rate and ideal for water treatment. It offers excellent dissolution of all components and reagents in the mixture.
