Abstract: The modification of concentration of liquids, comprises contacting the liquid with solid phase formed of capillary bodies (1)/capillary systems that are permeable to liquid and removing a part of the liquid by capillary bodies/passes through bodies and developing temporary local concentration changes during the movement of the liquid, which is used for the production of products of different concentrations. A part of the products passes through the capillary bodies. The modification of concentration of liquids, comprises contacting the liquid with solid phase formed of capillary bodies (1)/capillary systems that are permeable to liquid and removing a part of the liquid by capillary bodies/passes through bodies and developing temporary local concentration changes during the movement of the liquid, which is used for the production of products of different concentrations. A part of the product is passed through the capillary bodies. The liquid or a part of the liquid is absorbed by the single- or multiple-part capillary and pressed out, sucked off or removed, in which the fractions from the individual parts of the capillary body and the non-absorbed part of the liquid represent the obtained products. A dimension of the capillary body lies between 10 pm-100 nm. The ratio of the surface area of the capillary body to its pore volume is above 10 m2> per cm3>. The capillary body is composed of different materials and/or zones of different structure. A zone of the capillary body exhibits -hydrophilic - hydrophobic - lipophilic - lipophobic - electrophilic - electrophobic/nucleophilic characteristics. Flexible materials are used for the capillary body and/or the stable capillary system or a material for example a jelly or a pouring made of small bodies is used with a stabilizing support. A discharge for a product is limited by a restriction, a counter-pressure or an inhibition of the flow. The raw liquid (2) is brought into the system with increased pressure, which prevails at the product side in one of the discharges (3, 4). A negative pressure is produced at the product side in a discharge. The flow behavior of the raw liquid is influenced by mechanical bodies and/or appropriate shaping of the capillary bodies and/or their support. The temperature of the raw liquid and/or the capillary body is modified for the achievement of a definite result. A device or a part of the device is exposed to direct or an alternating field, for example an electrical or magnetic field. The electrical potential of liquids or parts of the liquids or of the components (capillary bodies, housing (8), and inlets and discharges) are modified or influenced. Materials are added to the raw liquid to modify the characteristics of the raw liquid. The raw liquid is subjected to a pre-treatment (cleaning, filtering, modification) process. A capillary body is used to reduce the absorption of a minimally-present substance dissolved in the raw liquid into the capillary body. Concentration of a dissolved solid in a solvent, concentration of a dissolved solid mixture in a solvent, concentration of a solved solid in a solvent mixture, concentration of a solved solid mixture in a solvent mixture, mixing ratio of a solvent mixture, production of more than two products with different concentrations, removal of certain components from solutions and quantitative ratio of emulsions are modified by using the device for the modification of concentration of liquids. Independent claims are included for: (1) a procedure for the separation of a mixture from soluble solids; and (2) a device for the modification of concentration of liquids.
