Claims (10)

1. Förfarande för avlägsning av suspenderat finför-delat fastämne frän en utloppsström, varvid utloppsströmmen 5 förs genom ett öppencelligt kompressibelt hydrofobt poly-mermaterial och detta material pressas för att avlägsna det därvid bundna fastämnet för regenerering av materialet, kännetecknat därav, att nämnda öppencelliga kompressibla hydrofoba polymermaterial har bildats av ät- 10 minstone tvä successiva skikt av nämnda material, varvid skikten har ordnats sä, att de öppencelliga porerna av varje skikt är slumpmässigt riktade i förhällande tili porerna av varje angränsande skikt.
2. Förfarande enligt patentkravet 1, kanne- 15 tecknat därav, att polymermaterialet utgörs av poly-uretan eller ett styren-butadien-gummi, som har ca. 24 - 40 porer per 1 cm.
3. Förfarande enligt patentkravet 2, k ä n n e -tecknat därav, att polymermaterialet är ett nät- : 20 formigt polyesterpolyuretanskum av Q-typ eller Z-typ som har ca. 24 - 40 porer per 1 cm.
4. Förfarande enligt nägot av patentkraven 1, 2 eller 3,kännetecknat därav, att skiktet av polymermaterialet, genom vilket utloppsströmmen först leds, har 25 ett större antal porer per 1 cm än det följande skiktet med-ströms.
5. Förfarande enligt nägot av patentkraven 1, 2 eller 3, kännetecknat därav, att utloppsströmmen är en sekundär utloppsström frän ett pappersbruk och poly- 30 mermaterialet pressas vid "breakthrough"-punkten för att regenerera skummet.
6. Förfarande enligt nägot av patentkraven 1, 2 eller 3,kännetecknat därav, att den totala tjock-leken av de successiva skikten av polymermaterial är ca. 35 10 - 20 cm, varvid varje skikt har en tjocklek av ca. 2,5 -5 cm.
7. Förfarande enligt patentkravet 1 för avlägsning
