Definitions

  • the present invention relates to the use of a fulvic acid-containing starting material for inhibiting the formation of beer scale.
  • the present invention further relates to the use of a fulvic acid-containing starting material for removing beer scale.
  • Beer scale is a deposit of calcium oxalate, which accumulates on the inside of vessels in which beer is fermented. In this deposit, (anaerobic) bacteria may become established and they are then difficult to remove so long as they are protected by the (porous) beer scale. There is then also a considerable risk of contamination. Beer scale may also form in beer pipelines, casks and bottles in which beer is stored. Beer scale cannot be removed with acid but with a base, or EDTA. There are also breweries that scrape the beer scale off of the vessels. After the brewing process, these kettles must be cleaned with cleaning agents to remove the scale so as to prevent contamination.
  • the Russian publication RU2215594 relates to an aqueous composition that is usable on a metal surface.

  • the present inventors also found, surprisingly, that the use of said fulvic acid-containing starting material led to a method for removing beer scale.
  • One or more aims are thus achieved.
  • the term "fulvic acid-containing starting material” means a starting material in which fulvic acid is present. Other constituents may also be present besides fulvic acid.
  • the use of said fulvic acid-containing starting material is also to be perceived as a useful application of a residual stream.
  • humic acid may be mentioned as a fulvic acid- containing starting material of this kind.
  • An aqueous product stream obtained in a regeneration step, in particular an ion exchange step, from a drinking water production unit is preferably used as said fulvic acid-containing starting material.
  • Humic acids also called humic materials, consist of humic and fulvic acids, and are released in the decolorizing of drinking water. They are natural substances, degradation products of organic matter in low-oxygen conditions. Humic acids are obtained by means of so-called ion exchangers. These ion exchangers are washed (regenerated) periodically with salt water. The residual product largely consists of water, salt, and humic acids. Using a unique technology, water, salt and humic materials are separated from one another and these streams can be reused usefully. As a result, pure humic materials are obtained (liquid), which are - depending on the concentration - from yellow to brown in colour.
  • humic acids can be used advantageously for improving the fertility of agricultural land: they give structure to the soil so that it retains more water and nutrients, they improve the root growth of plants, serve as food for microorganisms and improve the uptake of minerals. Sustainable application of humic materials will thus ensure a higher plant yield, and at the same time there is less need to apply fertilizers and phosphate.
  • the aforementioned fulvic acid-containing starting material is to be regarded as an aqueous product stream that is obtained in the rinsing of ion exchangers.
  • Ion exchangers of this kind are used in drinking water production processes for decolorizing water.
  • the humic acids which colour the water, are taken up by a kind of resin, wherein the resin then exchanges ions, generally chloride ions, for humic acid molecules. If the resin becomes saturated, the ion exchanger must be regenerated. Cleaning is carried out with a solution of sodium chloride, wherein the regenerate (cleaning fluid with waste material) is cleaned by so-called dead end nanofiltration, wherein a considerable part of the regenerate is added to the fresh regenerate.
  • the remainder of the treated regenerate still contains humic acids and salt.
  • the aqueous product stream that is used in the regeneration of the ion exchangers has its salt removed, for example by diafiltration, and is in particular rich in humic and fulvic acids.
  • the content of humic and fulvic acids is between 10-30 wt.%, based on the weight of the residual stream.
  • Lower contents of humic and fulvic acids of the aforementioned residual stream may be obtained by the application of purification techniques.
  • the term "fulvic acid-containing starting material” is further to be understood as a "humus-rich residual stream", namely an aqueous stream that is rich in humic and fulvic acids.
  • humic acid is to be regarded as a general term for organic substances that are finally released through slow degradation of peaty soil and account for the yellowish colour of the groundwater in that district. Besides peat, humic acid also occurs in coal and lignite. A fulvic acid-containing starting material obtained in a process for decolorizing groundwater during a drinking water production process is preferred, from the viewpoint of the natural constituents and the sustainable reuse of residual streams.
  • the aforementioned fulvic acid-containing starting material is used in a beer brewing process, in particular in the fermentation process.
  • a beer brewing process There are in principle two different ways of fermenting beer.
  • the yeast slowly rises.
  • the yeast floats on the beer like a blanket. This method is called 'top fermentation'.

  • the present inventors also observed that the aforementioned fulvic acid-containing starting material can also be used advantageously in containers in which beer is stored. Beer scale formation may also occur in said containers, such as kegs and bottles. By adding the aforementioned fulvic acid-containing starting material, the formation of beer scale is counteracted or even prevented.
