Claims (14)
1. Metoda obrade hidrofilne tekućine koja sadrži mikroplastiku i/ili nanoplastiku, pri čemu spomenuta metoda uključuje korake dodavanja kolagenih materijala ili derivata kolagena u hidrofilnu tekućinu koja sadrži mikroplastiku i/ili nanoplastiku čija je hidrofilna tekućina prisutna u spremniku tako da adsorbira i/ili fizički veže spomenute mikroplastične i/ili nanoplastične materijale prisutne u navedenoj hidrofilnoj tekućini i odvaja navedene adsorbirane i/ili fizički vezane mikroplastične i/ili nanoplastične materijale od hidrofilne tekućine.
2. Metoda sukladno zahtjevu 1, naznačena time što je navedena hidrofilna tekućina odabrana iz grupe koju čine voda iz slavine, otpadna voda, podzemna voda, površinska voda, slana voda ili morska voda.
3. Metoda za koju se traži patentna zaštita prema zahtjevu 1 ili 2, naznačena time što je hidrofilna tekućina koja sadrži mikroplastiku i/ili nanoplastiku već podvrgnuta mehaničkom i/ili biološkom i/ili kemijskom koraku obrade.
4. Metoda za koju se zahtijeva patentna zaštita u bilo kojem od zahtjeva 1 do 3, naznačena time što je kolagen ili derivat kolagena koji se koristi odabran iz grupe koju čine kolagen, frakcija kolagena, hidrolizat kolagena, želatina ili hidrolizat želatine.
5. Postupak za koji se zahtijeva patentna zaštita prema zahtjevu 4, naznačen time, da hidrolizat kolagena ima molekularnu težinu od 500 do 5000 da bi se koristio kao kolagen ili derivat kolagena koji se koristi.
6. Metoda za koju se traži patentna zaštita u patentnom zahtjevu 5, naznačena time što hidrolizat kolagena ima molekularnu težinu od 1000 do 3000 da bi se koristio kao kolagen ili derivat kolagena koji se koristi.
7. Metoda sukladno bilo kojem od zahtjeva 1 do 6, naznačena time što se plin nosilac, poželjno zrak, dušik, kisik ili ugljični dioksid, propuhuje ili raspršuje u hidrofilnu tekućinu koja se tretira.
8. Metoda za koju se traži patentna zaštita u patentnom zahtjevu 7, naznačena time što se plin nosilac uvodi u hidrofilnu tekućinu pri brzini plina u rasponu od 1 do 100 Nm3/sat po 1 m2 površine hidrofilne tekućine u taj kontejner.
9. Metoda za koju se traži patentna zaštita u patentnom zahtjevu 8, naznačena time što se plin nosilac uvodi u hidrofilnu tekućinu pri brzini plina u rasponu od 1 do 50 Nm3/sat po 1 m2 površine hidrofilne tekućine u taj kontejner.
10. Upotreba kolagenskog materijala ili derivata kolagena u odvajanju mikroplastike i/ili nanoplastike od hidrofilne tekućine koja sadrži mikroplastiku.
11. Upotreba sukladno zahtjevu 10, naznačena time što je navedena hidrofilna tekućina odabrana iz grupe koju čine voda iz slavine, otpadna voda, podzemna voda, površinska voda, bočata voda ili morska voda.
12. Upotreba sukladno zahtjevu 10 ili 11, naznačena time što navedeni kolagenski materijal ili derivat kolagena ima veličinu čestica u rasponu od 100 do 1500 um.
13. Upotreba sukladno bilo kojem od zahtjeva 10 do 12, naznačena time što hidrolizat kolagena ima molekularnu težinu od 500 do 5000 da bi se koristio kao kolagen ili derivat kolagena koji se koristi.
14. Upotreba sukladno zahtjevu 13, naznačena time što se hidrolizat kolagena koji ima molekulsku masu od 1000 do 3000 Da koristi kao kolagen ili derivat kolagena koji se koristi.
