Definitions
- the ultraviolet radiation strikes the cell walls of the cells of the contaminants, causing pre-damage in the cell walls of the contaminants.
- the pores of the cells can be opened under certain circumstances and it comes to a "bleeding" of the cell.
- the chemically active substances, in particular the radicals can now easily penetrate into the cells and destroy them completely.
- the object of the invention can therefore be used so that no auxiliaries, e.g. Chemicals or biocides, and / or complementary dyes are used for the purpose of reducing the impurities.
- auxiliaries e.g. Chemicals or biocides
- complementary dyes e.g., IR-rays, IR-rays, and/or complementary dyes.
- auxiliaries and / or complements are advantageous to use auxiliaries and / or complements.
- color is added in an amount that is less than the amount that would be required without applying the voltage.
- An accurate knowledge of the concentration and the effect of chemically active substances in the water or the suspension opens up the possibility, excipients and / or complementary ⁇ colors in terms of a to be achieved result opti ⁇ times to dose and so the possible environmental impact too low hold.
- biocides, algicides, bactericides, fungicides and others which are sometimes used as auxiliaries, pollute the environment. Also a cost advantage is achieved by abandoning or curtailing ⁇ kende addition of dyes or excipients.
- a tertiary cycle in particular a cycle for purified wastewater.
- Microbiological contaminants which can lead to a reduction of the fiber or paper quality in papermaking, are, for example, microorganisms which release, among other things, carbohydrate-cleaved enzymes, such as the enzyme cellulase, with which the cellulose in the process decomposes as a fiber base is used as a decomposed, short-chain carbohydrate as food for the microorganisms.
- carbohydrate-cleaved enzymes such as the enzyme cellulase
- a previous solution to prevent this exploited aus ⁇ finally chemical methods, ie adding chemicals, especially biocides, such as lutaraldehyde, in the material cycle or the water cycle to kill the microorganisms and so the contamination both during the manufacturing process as well to minimize in the final product.
- the otherwise widely used agent Wasserstoffper ⁇ oxide H2O2 can often not be used, since the peroxide-cleaving enzyme catalase is often also miter Wegt and the hydrogen peroxide H 2 O 2 is rapidly decomposed.
