Abstract: The invention relates to a pasty washing agent for use in commercial laundering which contains a non-ionic surfactant, an organic and/or inorganic builder, a bleaching agent based on peroxygen, and optionally contains other common constituents. The inventive pasty washing agent is characterized in that it contains 30 wt. % to 60 wt. % of non-ionic surfactant, 0.5 wt. % to 5 wt. % of a fatty acid and/or fatty acid alkaline-salt, 5 wt. % to 15 wt. % of citrate and/or citric acid and 15 wt. % to 35 wt. % of an inorganic peroxygen compound. In addition, the pasty washing agent does not contain alkali metasilicate nor a bleach activator. In addition to exhibiting a good cleaning efficiency, the inventive agent has a disinfecting action.

Abstract: Process for the treatment of sewage by using conventional precipitants and flocculants, like silicates, iron- or aluminum salts or organic polymers, and in addition about 0.1-10 (0.03-3) g/l sewage of X-ray amorphous or crystalline, finely-divided alkali- and/or alkaline earth-alumosilicates of the formula:x cat.sub.2/n.Al.sub.2 O.sub.3.y SiO.sub.2where x=0.7-1.5; y=0.8-6; cat=Na, K, Mg or Ca; n=1-2. The compounds contain preferably bound water. The alumosilicate is added preferably in the form of an aqueous suspension (pH 3.5-5.0) to the sewage to be treated, adjusted if necessary to a weakly alkaline to weakly acid pH-value (5-10). The pH-value is preferably adjusted with strong acids, preferably sulfuric acid.In sewage from laundries, which can already contain x g alumosilicates, the amount is reduced by x g.Advantage: Compared to known processes, the dirt elimination rate is greater and/or the consumption of precipitants is reduced.

Abstract: A process for the preparation of a cation-exchanging alkali metal aluminosilicate granulate having a particle size of from 0.05 to 1 mm comprising (a) charging a finely-divided, crystalline water-containing alkali metal aluminosilicate powder having a calcium binding power of from 50 to 200 mg CaO/gm of anhydrous aluminosilicate and a particle size of less than 30.mu. into a conventional granulator, (b) adding thereto (i) m moles of SiO.sub.2 as an aqueous alkali metal silicate solution or an aqueous silicic acid sol, and (ii) n mols of Al.sub.2 O.sub.3 as an acidic hydrolyzing aluminum salt and/or alkali metal aluminate powder and/or an aqueous alkali metal aluminate solution, (c) mixing until the moisture is uniformly absorbed and a granulate with a particle size of 0.05 to 1 mm is formed, and (d) drying said granulate at 80.degree. to 150.degree. C.

Abstract: An improvement in the machine washing of solid soiled materials comprising withdrawing and recycling the wash liquor in contact with said solid soiled materials through a silicate cation exchange compound having some combined water and a particle size of at least 10.mu. of the formula:(M.sub.2/n O).sub.x.Me.sub.2 O.sub.3.(SiO.sub.2).sub.ywherein M is a cation of valence n exchangeable with calcium, Me is a member selected from aluminum and boron, x is a number from 0.7 to 1.5 and y is a number from 0.8 to 6, said silicate compound having a calcium binding power of at least 50 mg of CaO per gram, said silicate compound being maintained out of contact with said solid soiled materials, for such time that the recycling wash liquor has passed through said silicate compound at least twice, in the presence of other soluble washing and cleaning compounds, while reversing the direction of flow of said wash liquor through said silicate compound repeatedly.
