Definitions
- the invention relates to a method for cleaning drain pipes for fatty waste water from the household or from commercial companies, nitrogen-containing compounds being added to the fat-degrading and / or fat-emulsifying bacteria contained in the waste water.
- Supplines are essential substances that are part of the basic structure of the cell and cannot be synthesized by individual organisms. It is e.g. amino acids, purines, pyrimidines, organic acids, carbohydrates and vitamins, in particular phenylalanine, arginine, aspartic acid, oxalic acid, malic acid, malonic and propionic acid. In terms of their function and concentration, Suppline differ significantly from nutrients. They correspond to the vitamins in animal and human nutrition.
- the following compounds can be specified as nutrients which fundamentally differ from supplins: ammonium, nitrate and phosphate ions, glucose, polysaccharides, proteins and carbohydrates.
- supplins ammonium, nitrate and phosphate ions, glucose, polysaccharides, proteins and carbohydrates.
- the supplink combination enables one rapid growth of the desired bacteria, which leads to a dissolution of the annoying plug of fat in the drain pipe.
- the fat-degrading or emulsifying bacteria are a broad spectrum of bacteria that are normally contained in the wastewater itself.
- a detergent can be added to promote the penetration of the suppline into the fat plug and to support the microbial fat solution.
- the same purpose alone or in combination with the detergent is the addition of a CO 2 -developing powder, for example effervescent powder, which consists of about 50 percent by weight sodium bicarbonate and about 50 percent by weight tartaric acid.
- This application discloses a two-stage system of action, according to which in a first phase the germ-inhibiting substances and in a second phase the germ-promoting substances bring about wastewater treatment.
- a cleaning block for toilets which is dissolved in the cistern and has a composition of 5 to 85% by weight of one or more anionic surface-active agents, 2 to 50% by weight of one or more agents to control the solubility and 0.5 to 50% by weight of at least one water-soluble polyvalent metal salt, such as magnesium sulfate containing water of crystallization.
- a liquid drain cleaner also contains urea, a urea derivative, a salt of urea and / or a salt of a urea derivative and 2.
- a solid drain cleaner additionally urea, a urea derivative Salt from the urea and / or a salt of a urea derivative and / or anhydrous magnesium sulfate can be added, growth factors in the form of supplins being largely excluded and a small amount of germ-inhibiting organic substance being present.
- the invention accordingly relates to a method for cleaning drainage pipes for greasy waste water from the household or commercial companies, nitrogen-containing compounds being added to the fat-degrading and / or fat-emulsifying bacteria contained in the waste water, which is characterized in that 1. a liquid drain cleaner additionally urea, a urea derivative, a salt of urea and / or a salt of a urea derivative and 2. a solid drain cleaner additionally urea, a urea derivative, a salt of urea and / or a salt of a urea derivative and / or anhydrous magnesium sulfate are added, growth factors being added are largely excluded in the form of supplins, and in 1. and 2. the amount of germ-inhibiting organic substance is below 0.5 g / kg, preferably below approximately 0.3 g / kg, in particular below approximately 0.1 g / kg of drain cleaner .
- the addressed additive in the form of the germ-promoting organic substance can accordingly contain an open-chain or cyclic compound of the formula (I) R1R2N-CO-NR3R4, in which R 1 to R 4 are each independently open-chain or cyclized and can have the following meanings: hydrogen, a lower alkyl - Group with 1 to 4 carbon atoms, a cycloalkyl group with 3 to 6 carbon atoms, an aryl group in the form of a phenyl or naphthyl radical, an aralkyl group with 7 to 18 carbon atoms, or an O-, S- or N-containing heterocyclic group having 2 to 5 carbon atoms, the compound of the formula (I) being wholly or partly in the form of a salt.
- R 1 to R 4 are each independently open-chain or cyclized and can have the following meanings: hydrogen, a lower alkyl - Group with 1 to 4 carbon atoms, a cycloalkyl group with 3 to 6 carbon atoms, an
- the respective radicals R 1, R 2, R 4 and R 4 are preferably hydrogen, since the corresponding starting compounds are commercially available or easier to prepare.
- Particularly suitable in the context of the invention are the substituents which are specified in the above definition of the invention.
- the lower alkyl groups with 1 to 4 carbon atoms are in particular the methyl, ethyl, n-propyl, i-propyl and the various isomers of the butyl group.
- the cycloalkyl group with 3 to 6 carbon atoms in particular includes the cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl radical, the aralkyl group with 7 to 18 carbon atoms in particular the benzyl and phenethyl group, the alkylaryl group with 7 to 18 carbon atoms in particular the tolyl group and among the heterocyclic group with 2 to 5 carbon atoms, in particular those in whose heterocyclic ring there is at least one oxygen, sulfur or nitrogen atom, suitable examples being the radicals of oxirane, tetrahydrofuran, dioxane and pyran .
- the compounds of the formula (I) can also be used in the form of their salts or other precursors, which can promote solubility. In individual cases this can only lead to the desired solubility. Compounds can therefore be considered which only release the compounds of the formula (I) in the aqueous medium or allow their activity to develop there.
- the following quantities always relate to the compounds of formula (I) as such or their proportion within the suitable derivatives or compounds.
- any suitable salts of the ureas or urea derivatives mentioned can be used, provided they do not impair the desired mechanism of action.
- chlorides, sulfates, in particular hydrogen sulfate, phosphates, in particular the hydrogen phosphates are suitable.
- Urea phosphate is particularly effective. Urea phosphate, in pure Form crystallized, is colorless, has a melting point of 118 to 119 ° C, is soluble in water, alcohol, acetic acid, glycerin, ethylene glycol and the like. The aqueous solution reacts acidic (1 percent solution pH 1.8).
- N / P source it offers a further advantageous practical use due to its acid action in soldering agents, melt fluxes, pickling agents,
- the urea in an amount of about 0.1 to 20 percent by weight, in particular about 5 to 15 percent by weight, the urea phosphate in an amount of about 0.2 to 40 percent by weight, in particular 2 to 30 percent by weight, could be stated. and the magnesium sulfate in an amount of about 5 to 95 percent by weight, in particular about 20 to 70 percent by weight, based on the solid or the solid cleaner.
- the essence of the invention is therefore the solid or liquid drain cleaner urea and its derivatives, including its salts, e.g. Add urea phosphate, especially in combination with enzymes and microorganisms that break down fat, protein and carbohydrates.
- urea phosphate especially in combination with enzymes and microorganisms that break down fat, protein and carbohydrates.
- anhydrous magnesium sulfate is added to it. Due to its property profile, this can also be used in isolation.
- urea and its designated derivatives both as such or in salt form, not only physically promote the hydrophilization of plugs and their parts due to their water-binding and swelling-promoting and protein-dissolving properties, but also their physical explosion or dissolution.
- penetration and degradation performance of natural or added microorganisms and enzymes on the graft and its parts are promoted and thus the biological-chemical degradation is accelerated, for example also in wastewater.
- the growth factors described in the prior art see above proposal according to EP-B-236
- anhydrous magnesium sulfate is a completely safe, consumer and environmentally friendly neutral salt.
- anhydrous magnesium sulfate can also be replaced by other anhydrous neutral salts which correspond to its property profile, and that such salts thus develop a new mode of action in solid drain cleaners which has not hitherto been found in the prior art.
- Example 1 (destruction of the plug in the drain pipe)
