Abstract
En dispersjon med en vandig kontinuerlig fase blir membranflltrert i ett eller flere membranflltrerings- trinn, hvor en tilførselsdispersjonsføde til en filtrerlngsmembran blir separert i hvert trinn i et retentat tilbakeholdt av filtrerlngsmembranen og et permeat som går gjennom nevnte filtreringsmembran, hvorved retentatet fra ett trinn kan bli benyttet, hvis ønskelig, som en fødedlspersjon eller en del derav i ett eller flere påfølgende trinn. Permeatet som er resultat fra ett eller flere trinn, blir utsatt for en konsentrerlng i form av en konsentrert fraksjon inneholdende en øket konsentrasjon av tørrstoff eller en del derav tilstede i permeatet, og denne konsentrer- te fraksjonen blir returnert som en del av fødedisper- sjonen i en eller flere membranfiltreringstrinn. Et system for membranfiltrering av slike dlspersjoner, omfatter en eller flere membranflltreringsenheter, hver forbundet med et tllførselsrør, et retentat- utløpsrør og et permatutløpsrør, en eller flere av de permeate utløpsrørene (S11"1, 8n, 8n+1, . . . ) er koblet til en eller flere konsentrerende enheter (1011'1, I0n, 10n+1, ...) tilpasset til å separere permeatet l en fortynnet fraksjon og et konsentrat, hver konsentrer- ende enhet er utstyrt med et utløp (1211-1, I2n, 12n+1,...) for den fortynnede fraksjonen og et konsen- trasjonsutløpsrør (1411-1, 14n, 14n+1,...) for konsen- tratet, nevnte konsentreringsutløpsrør er koblet til et retur-rør (1611-1, 16n, 16n+1, ...) som åpner til en eller flere av tllførselsrørene (211"1, 2n, 2n+1, . ..) i membranfiltrer ingsenhetene.A dispersion with an aqueous continuous phase is membrane filtered in one or more membrane filtration steps, whereby a feed dispersion feed to a filtering membrane is separated at each stage of a retentate retained by the filtering membrane and a permeate passing through said filtration membrane used, if desired, as a birth portion or part thereof in one or more subsequent steps. The permeate resulting from one or more steps is subjected to a concentration in the form of a concentrated fraction containing an increased concentration of dry matter or a portion thereof present in the permeate, and this concentrated fraction is returned as part of the feed dispersion. in one or more membrane filtration steps. A system for membrane filtration of such parts, comprises one or more membrane filtration units, each connected with a feed tube, a retentate outlet tube and a permeation outlet tube, one or more of the permeate outlet tubes (S11 "1, 8n, 8n + 1, ...). is coupled to one or more concentrating units (1011'1, I0n, 10n + 1, ...) adapted to separate the permeate into a dilute fraction and a concentrate, each concentrating unit being provided with an outlet (1211-1 , I2n, 12n + 1, ...) for the diluted fraction and a concentration outlet tube (1411-1, 14n, 14n + 1, ...) for the concentrate, said concentration outlet tube is connected to a return tube ( 1611-1, 16n, 16n + 1, ...) which open to one or more of the feed tubes (211 "1, 2n, 2n + 1, ...) in the membrane filtration units.
