Description

INORGANIC COMPOSITION, PROCEDURE FOR ITS PREPARATION AND METHOD FOR ITS USE BACKGROUND OF THE INVENTION The present invention relates, in general, to coagulants for water treatment purposes. In general, coagulants are used for the imaging of suspended solids in aqueous systems. Coagulants typically fall into the general category of inorganic compounds (metallic lenses, lenses, glasses) or organic compounds (water-soluble poly-molecules). Examples of inorganic coagulants widely used are aluminum sulfate AI2 (SO4) 3, chlorine of AIC 13 luminium, alu minium hydrochloride AI2 (OH) 5CI, ferric chloride FeCI3, ferric sulfate Fe2 (SO4): ?, and calcium chloride. Examples of water-soluble polymers or of polyelectrolyte solution, commonly used are p-DMDAAC (polychloro methyl diali mon monium chloride) and Epi-DMA polya mine. Many inorganic coagulants are compatible with cationic polyelectrolytes of solution and can be combined to form stable combinations. In recent years, many different mixing formulations of an inorganic coagulant Re: f: 123228 have been presented and marketed with a highly charged cationic, solution, and ionic solution. An example of an inorganic coagulant / polymer mixture can be: 5 parts of a standard solution of AICI3, 28 ° Baumé, mixed with 1 part of polyamine Epi-DMA. More examples, limits and ranges are explained in U.S. Patent Nos. 4,746,457, 4,800,039, and 5,035,808, from Calgon Corporation; and additionally in U.S. Patent Nos. 2,862,880, 3,285,849, 3,472,767, 3,489,681, 3,617,569, 4, 137, 165, 4,450,092, 4,582,627, 4,610,801, and 4,655,934, the descriptions of which are hereby incorporated by reference in their entirety. Normally, these compositions are physical mixtures of a trivalent metal salt solution and a water soluble polymer solution, which is a simple mixture of the components, where the two components are retain their identity or original chemical composition, but which provides utility and advantages such as: 1. a synergy from the addition of the inorganic and polymeric coagulants at the same time, as a mixture; and 2. ease of use - the use of one product instead of two (thereby eliminating systems, equipment and handling for food).

Systems for wastewater treatment typically require the use of trivalent metal salts, a polymer, or a combination of both in the coagula ion process. Both ferric coagulants, as well as mixtures with FeCI3, and aluminum coagulants, such as alum or mixtures of AI2 (OH) 5CI are often used for these processes. The two coagulants, the ferric and the aluminum, provide different desirable properties. However, these coagulants are usually incompatible with each other. Accordingly, it was desired in the art to develop a single coagulant that combines the desirable properties of ferric and aluminum coagulants.

BRIEF DESCRIPTION OF THE INVENTION The present invention comprises a composition which is the product of the reaction of a trivalent metal salt, excluding the salts and chromium, an acid phosphorous compound and an aluminum hydroxy chloride, and a process for the preparation of the same. The method of use, according to the present invention, comprises adding this reaction product, in an effective amount, to the solution to be treated. The composition of the present invention is an excellent and unique anti coagulant for most water treatment applications. As used herein, the phrase "effective amount" refers to the amount of the claimed reaction product that is useful to treat (coagulate), at least partially, the impurities in wastewater or in the system to be subjected to treatment.

BRIEF DESCRIPTION OF THE FIGURES The composition mentioned above will become more apparent when referring to the following detailed description, taken in conjunction with the appended figures, in which: Figure 1 is an NMR spectrum of AI-27, monoa phosphate I um I nio; Figure 2 is an NMR spectrum of AI-27 of aluminum chlorohydrate; and Figure 3 is an NMR spectrum of AI-27 of the reaction mixture, iron (III) chloride, monoaluminium phosphate and aluminum chlorohydrate. These figures are discussed in detail later.

DETAILED DESCRIPTION OF THE INVENTION The present invention was discovered when the inventors tried to obtain the desirable properties of the FeCl3 mixtures and the AI2 (OH) 5CI mixtures, by mixing these two inorganic compounds and then combining the resulting mixture with a for cationic ion and other ingredients. However, they discovered that mixtures of trivalent metal salts, such as FeCl3 and aluminum hydroxy chlorides, such as AI2 (OH) 5CI, are incompatible and that all attempts to combine these mixtures resulted in a gelled reaction product. / so id, which was not useful. Unexpectedly it was discovered that the solution of FeCI3 and the solution of AI2 (OH) 5CI can be stabilized and combined through the use of a third ingredient, monoaluminum phosphate. The inventors have discovered a method for combining these previously incompatible coagulants and creating a stable, complex ionic coordination compound which exhibits greater efficiency as a coagulant for industrial and municipal water treatment. The inventors have discovered a composition, and the process for preparing the same, comprising the reaction product of a trivalent metal salt, different from the chromium salts, an aluminum hydroxy chloride and an acid phosphorous compound which acts as a compound of stabilization. The preferred process for preparing the present invention is the addition of the acidic osporous compound (stabilizer) to the trivalent metal salt, followed immediately by the addition of the aluminum hydroxy chloride. A slight exotherm occurs from the addition of the acid phosphorous compound (stabilizer) to the metallic salt t ivalent. A larger and more vigorous exotherm results from the subsequent addition of the aluminum hydroxy chloride. Based on this exotherm, as well as color changes and partial precipitation (and re-dissolution), the components are thought to react and a new compound is formed. Although the order of addition of these compounds can be altered to form the new compound, the order of addition mentioned above is preferred. If the trivalent metal salt and the aluminum hydroxy chloride are combined without the acidic phosphorous compound, a suspension will form which will generally solidify in less than one hour. In order to create a stable final product, if this order of application is used, the acidic phosphorous compound should be added to this mixture before solidification, or preferably in a time of 40 minutes. However, reconstitution after solidification is possible by the addition of the acid phosphorous compound. The least preferred order of addition is when the acidic phosphorous compound is mixed only with the aluminum hydroxy chloride, because a solid mass will form almost instantaneously. However, this solid mass can be reconstituted by the addition of FeCl 3 - For these reasons, the order of addition mentioned above is preferred. This new resulting compound is stable and appears to be of a composition different from that of the compounds used in the preparation preparation. The conclusion that a new compound is formed is supported by Figures 1-3 which illustrate the NMR spectra of AI-27 for a compound formed by the reaction of the formula volume of 10 parts of FeCl 3 (approximately 40% of the crude active material in Water), 3 parts of monoaluminium phosphate (AI (H2P? 4) 3-XH2O) (about 50%, by weight, in water), and 5 parts of AI (OH) 5 CI (about 50%, by weight, in water) ). The commercially available FeCl3 solution is from 38% to 42% of the initial active material, in water. The commercially available monoaluminum phosphate and the AI (OH) 5CI are both 50% by weight, in water, plus or minus 1% to 2%. The combination of shape and position of a peak give structural information in NMR spectroscopy. The position is based on a relative marker with respect to a selected standard material and is measured in ppm settings in the frequency. The standard reference material used in these spectra was aluminum oxide (Al203) at 0 ppm. The shape of the peak (singlet, doublet, etc.) depends on the interaction of the nuclei with neighboring atoms. The combination of shape and position of the peak is a function of the environment of the nuclei and, consequently, of their structure. Figure 1 is an NMR spectrum of AI-27, of monoaluminum phosphate. This spectrum shows a single band centered at approximately -77.7 ppm, with respect to the standard. The width of the peak is indicative of the structure in the solution. Figure 2 is an NMR spectrum of AI-27, of aluminum chlorohydrate (A 12 (O H) 5 C I). This spectrum shows a very broad group of peaks centered at approximately -57.8 and -68.6 ppm, where the first peak is the strongest band. This spectrum shows two overlapping peaks. There are also two significantly smaller peaks to both the os of these two main bands, which are probably minor impurities. It is known that this material is polymeric in nature. In general, the higher the molecular weight of a material, the wider the spikes become. Figure 3 is an NMR spectrum of AI-27 of the reaction mixture of the present invention. This spectrum shows the product of the claimed reaction mixture of iron (III) chloride, monoaluminium phosphate and aluminum chlorohydrate, according to the present reaction, using the concentrations and parts by volume of these three compounds in the preferred embodiment. In Figure 3, the NMR peak of aluminum is a much sharper singlet and is shifted to a position of about -26.2ppm with respect to the standard. These changes indicate that a reaction has taken place, that the two component raw materials (iron (III) chloride and aluminum hydrochloride) are most likely the limiting reactants in this reaction, and that the structure of the final product is simpler than the of the aluminum hydrochloride precursor. Aluminum exists in a simple type of chemical environment, here is the foundation for the proposed structure of a new compound.

The molecular formula of this preferred embodiment, which is the object of Figure 3 is: iron (III) salt of [Aln (OH) a (H2PO4) b (CI) c (H2?)] 3 p "a" b "c where a + b + c> 3n This new composition is the product of a reaction of the Lewis base acid type, in which a complex, stable coordination ionic compound is formed, as indicated below: A + B "intermediate compound" (observed temperature increase of 4 ° C) "intermediate compound" + C? New compound (observed temperature increase of 20 ° C) where: (% active base) A = 17.5% iron chloride - twenty% B = Phosphoric Acid, Aluminum Salt (3: 1) 8% - 10% C = Aluminum Chloride, Basic 11.0% - 13% A typical structure of this new compound, of the preferred embodiment, is shown below, where the number of H2O, Cl, OH and H2P04 ligands can vary, as well as their position on the metal ion in the coordination complex. The nature of the bond between each ligand and the central metal atom is covalently coordinated.

H, 0 H2O +1 Cl OH H2O .Cl Al Fe H2PO4? H2O 'Cl H, 0 H2O The preferred embodiment of the composition of the present invention, by volume, is: FeC (aqueous solution of approximately 40% of active raw material in water) 3 of monoaluminum phosphate (AI (H 2 P 04) 3-XH 2 O) (approximately 50% by weight, in water) 5 of AI2 (OH) 5CI (approximately 50% by weight, in water) 1 of CaCl2 (30% solution) 2 of CA-250 (polyamine Epi-DMA) (50% in weight, in water) Multiple experiments have been carried out involving the modification of the volume of the ingredients mentioned above. It has been determined that, although the volumes mentioned above provide the preferred combination, these ratios can be altered to various degrees, while still maintaining a stable reaction product and the desired coagulation properties. It has been determined that (using the concentrations stated above) the volume of the FeCl3 component can be varied from 3 to 30 parts, the monoaluminum phosphate can be varied from 0.5 to 10 parts and the AI2 (OH) 5CI can be increased to 20 parts However, the upper limit of the volume of Al2 (OH) 5CI appears to be 20 because precipitation begins to occur at this level. Although the quality of the resulting compounds varied proportionally by deviating from the preferred embodiment, the resulting compounds provided stable reaction products. Additional tests have been carried out by varying the combinations of the different trivalent metal salts, the acid phosphorous compounds and the aluminum hydroxy chlorides, as well as the volumes of each of these components. The example mentioned below shows the results of selected tests on the variations in volume and component. The volumetric relationships established above, for the components of the preferred embodiment, can also be applied to the various combinations claimed of the other trivalent metal salts, acid phosphorous compounds and aluminum hydroxychlorides. It is known to one skilled in the art that these various compounds can be obtained in various concentrations. In order to obtain the most preferred ratio of the components, of the various substitution components of varying concentration, one must obtain the same ratio of the molar amounts of the ferric, phosphate or phosphite and aluminum, as those of the preferred embodiment mentioned above. For example, phosphoric acid is commercially available at a concentration of about 85% by weight, in water, compared to about 50% by weight, monoaluminum phosphate. Therefore, a component of different concentration can be used if the correct molar ratio is obtained. It appears that the components of calcium chloride and CA-250 are presented only as a physical mixture with the compound that is the result of the reaction. The mixture resulting from the reaction product and CaCI2 and CA-250 (polyamine Epi-DMA) is a "cleaning clot" that functions as a coagulant and a flocculating substance and, as mentioned above, could be useful in many procedures for water treatment. Other standard additives can also be mixed with the product of the reaction.

Instead of CA-250 (polyamine Epi-DMA), p-DMDAAC can be used under certain circumstances in the physical mixture with the object of the reaction product. The p-DMDAAC can be used when the trivalent metal salt of FeCl 3 (in the preferred embodiment) is diluted 10 times to 40% with water, before the addition of the acid phosphorous compound and the aluminum hydroxy chloride. In order to use p-DMDAAC with the reaction product already prepared, of the preferred embodiment, the entire product of the reaction must be diluted 10 times to 40% with water, before the addition of p-DMDAAC. If the phosphoric acid is substituted by the monoaluminium phosphate of the preferred embodiment, the dilution of the FeCl 3 or the complete product of the reaction should be by 10, up to 80%, with water, otherwise precipitation will occur. Tests have also been carried out involving the variation of the amounts of CaCl2 and the amount of CA-250 (polyamine Epi-DMA). The volumes of these compounds have been varied both together and independently. The variation of these two components seems to have a negligible effect on the formulation. As mentioned above, although the preferred embodiment uses FeCl3 as the trivalent metal salt, substitutions of the monoaluminum phosphate as the acid phosphorous compound, and of AI2 (OH) 5CI as the aluminum hydroxy chloride, can be made for each of these compounds , while still resulting in a stable, effective reaction product. The preferred trivalent metal salts are those of Group 8. The most preferred trivalent metal salts are metal halides. However, the most preferred trivalent metal salts are ferric, such as FeCl3, Fe2 (S04) 3, FeBr3 and Fe (N03) 3. Additionally, mixtures of the aforementioned compounds can be used. The ferric halide is the most preferred, while the ferric chloride is the most preferred. The preferred anions of the salt are the chloride and the halide. The sulfate is a less preferred anion of the salt. Nitrate can also be used as an anion for salt. The preferred acidic phosphorous compounds of the present invention are selected from the group consisting of acid phosphites (including phosphorous acid), acid phosphates (including phosphoric acid) and phosphonic acid. Acid phosphorous compounds having the following formula can be used: MnHxP04 Where: M = cation, such as a metal or ammonium; n = 0 to 2; x = 1 to 3; q = 3 or 4 For example, the following acid phosphorous compounds can be used: monoaluminum phosphate (A I (H 2 P O 4) 3 • X H 2 O), phosphoric acid (H 3 PO 4), phosphorous acid (H3P03), sodium monobasic phosphate (NaH2P0), sodium dibasic phosphate (Na2HP04), HEDP (CH 3 C (OH) (PO 3 H 2)), vinyl phosphonic acid (H2C) = CHP (0) (OH) 2), dimethyl phosphite ((CH302) P2 (0) H), (NH4) 2HP04, NH4H2PO4, potassium monobasic phosphate (KH P04) and K2HP04. The most preferred acid phosphorous compounds are those that are not organic, because of their low cost. The aluminum hydroxy chloride compounds, which can be used in the formulation of the composition of the present invention are those of the general formula AI2 (OH) and Clz, where y = 0.1 to 5; and z = 1 to 5.9. More preferred are those where y = 1 to 5 and z = 1 to 5. The most preferred are those where y = 1.8 to 5 and z = l to 4.2. To prepare the claimed reaction product, AICI3 can be used as the trivalent metal salt and combined with AI2 (OH) sCI and a stabilizer (acid phosphorous compound). An exotherm will be present and a reaction product will be formed. The A I C i 3 can also be used as a substitute for the aluminum hydroxy chloride component and combined with FeCl 3 and a stabilized one. However, under these circumstances, a reaction product is not formed, rather, a mixture is formed. However, this mixture exhibits good coagulation properties. Experiments have also been carried out where the compound CaCI2 has been substituted with MgCl2 and BaCI2, without seriously detrimental to the characteristics of the resulting mixture with the reaction product. Also the CA-250 (polyamine Epi-DMA) can be replaced by other polyamines Epi-DMA. CA-250 is preferred because of its relative molecular weight, in the low to medium range. CA-250 s a commercial product of polyamine, sold by Calgon Corporation. This new compound has proved to be an excellent and unique coagulant for most water treatment applications, including the treatment of E-coated waste, coagulation of water with paint residues, the elimination of the viscosity of paint in waste. oily and in solvents with paint residues. It also has utility for the treatment of wastewater in general, the treatment of municipal wastewater, elimination of metals from water, wastewater from papermaking, water containing chemical compounds, water containing organic compounds, water containing biological compounds, processing waste from poultry farming, solutions that contain dyes, clarification for process water (such as municipal drinking water and industrial purification), oil / water separation, water containing suspended solids, color removal (colorful solutions), residual suspensions of clay, coal waste, water for the processing of minerals, oily waste, water containing suspended solids, water that contains solids from the paint, and others. The resulting new compound has also been shown to remove metals from water, including heavy metals such as lead and nickel. The coating residues E are the wastewater generated from the electrolytic sizing process. The method of using the new compound for coagulation in these various systems consists of adding the new compound to the system in an effective amount. This new compound can also be used to strengthen coagulation. Reinforced coagulation is the reduction of total organic pollutants (TOC). The reduction of organic contaminants in drinking water is desirable to minimize the formation of chlorinated hydrocarbons that are formed during the chlorination process. The most preferred method for producing the claimed reaction product comprises the following steps: 1. At room temperature, add 3 parts, by volume, of a monoaluminium phosphate solution (approximately 50% by weight, in water), to 10 parts. , by volume, of an aqueous solution of FeCI3 (approximately 40% of the active raw material in water). During the addition of the monoaluminium phosphate solution to the FeCl 3 solution, a certain degree of the reaction will be carried out. There may be some partial precipitation and color changes - and striations in the solutions. However, when the reaction is complete, everything is in the solution and appears stable. 2. Next, 5 parts, by volume, of the aluminum hydrochloride solution are added (about 50%, by weight, in water) to the mixture of FeCl3 and monoaluminium phosphate (and the additional reaction is carried out). The resulting solution experiences a violent exotherm. The solution is heated and the solution becomes homogeneous. When the solution cools, it remains compatible and homogeneous. 3. Preferably, then, 1 part, by volume, of CaCl2 (30% solution) and 2 parts, by volume, of a polymer, such as CA-250 (polyamine Epi-DMA, 50% by weight) are added. The CaCl2 is added to provide hardness and the polymer to strengthen the coagulation and start the flocculation (to help form the initiation flock). It seems that there is no further reaction when the CaCl2 is added to the polymer. As mentioned above, it will be apparent to anyone trained in practice that this procedure can be duplicated using the other trivalent metal salts, the acid phosphorous compounds, the aluminum hydroxy chlorides that are claimed here, if the same ratios are used. molars mentioned.
