Abstract

Postupak za smanjenje organskih komponenata u vodi, naznačen time, što se u kontakt sa vodom koja treba da se prečisti dovode- prirodni kalcijum-karbonat koji reaguje površinski, i- hidrofbni adsorbent, koji se bira iz grupe koju čine talk, hidrofobizovani kalcijum-karbonat, hidrofobizovani bentonit, hidrofobizovani kaolinit, hidrofobizovano staklo ili bilo koja njihova smeša, gdeprirodni kalcijum-karonat koji reaguje površinski, je proizvod reakcije prirodnog kalcijum-karbonata sa nekom kiselinom i ugljen-dioksidom, nastalim in situ tretmanom sa kiselinom, i/ili dovedenim spolja, a ovaj prirodni kalcijum-karbonat koji reaguje površinski se priprema kao suspenzija u vodi, koja ima pH veće od 6,0, mereno na 20°C; igde bar jedna organska komponenta ne sadrži smolu, koja nastaje u procesu proizvodnje papira ili procesu pulpiranja, ukoliko se bar jedna organska komponenta bira iz grupe koju čine surfaktanti; holesterol; endokrino razgrađena jedinjenja; aminokiseline; proteini; ugljenihidrati; agensi protiv penušanja; agensi za modifikovanje, koji se biraju iz grupe koju čine dimer alkil ketena (AKD), anhidrid alkenil ćilibarne kiseline (ASA) ili njihove smeše; polivinilacetati; poliakrilati; kopolimeri stiren-butadien; mikroorganizmi; mineralna ulja; biljna ulja ili masti; ili bilo koja njihova smeša.Prijava sadrži još 33 patentna zahteva.A process for reducing organic components in water, which is brought into contact with water to be purified - natural calcium carbonate, which reacts surface, and - hydrophobic adsorbent, selected from the group consisting of talc, hydrophobized calcium carbonate , hydrophobized bentonite, hydrophobized kaolinite, hydrophobized glass or any mixture thereof, where naturally occurring superficial calcium caronate is the product of the reaction of natural calcium carbonate with an acid and carbon dioxide formed by in situ treatment with an acid and / or brought from outside , and this naturally occurring reactive calcium carbonate is prepared as a suspension in water having a pH greater than 6.0 measured at 20 ° C; that at least one organic component does not contain a resin produced in the paper-making or pulping process, if at least one organic component is selected from the group consisting of surfactants; cholesterol; endocrine degraded compounds; amino acids; proteins; Carbohydrates; antifoaming agents; modifying agents selected from the group consisting of alkyl ketene dimer (AKD), alkenyl amber anhydride (ASA) or mixtures thereof; polyvinyl acetates; polyacrylates; styrene-butadiene copolymers; microorganisms; mineral oils; vegetable oils or fats; or any mixture thereof. The application contains a further 33 claims.
