1. Fremgangsmåde til kraftig koncentrering af vandige opløsninger, der indeholder termisk følsomme organiske bestanddele og er med eller uden mineralbestanddele, hvor først en større del af vandet (2) ekstraheres ved hjælp af membranfiltrering (MF) fra opløsningen (1) til forkoncentrering og fjernes fra processen, hvorefter opløsningen (3), der er forkoncentreret på denne måde, udsættes for en frysekoncentreringsprocedure (FC), hvor yderligere vand i form af separeret iskrystallisat (4) ekstraheres fra opløsningen, hvor denne koncentrering fremkaldes ved frysekoncentreringsproceduren (FC), indtil der er opnået en viskositet i moderopløsningen (6) på mindst 0,0002 m2/s, der er kendetegnet ved, at det separerede iskrystallisat (5) fra frysekoncentreringen (FC) med moderopløsningen klæbende dertil som en suspension returneres (7) til membranfiltreringen (MF) opstrøms for membranfiltreringen (MF) eller efter smeltning af iskrystallisatet.
2. Fremgangsmåde ifølge krav 1, der er kendetegnet ved, at koncentreringen fremkaldes ved frysekoncentreringsproceduren, indtil der er opnået en viskositet i moderopløsningen på mindst 0,00025 m2/s, fortrinsvis mindst 0,0005 m2/s, især mindst 0,001 m2/s.
