Abstract

A method for fractionating and concentrating sulfite residual liquid, which has previously been devoid of free SO2 by steam stripping, cooled and released from fibers by filtration, by means of a combination of ultrafiltration and reverse osmosis, characterized by 1) subjecting a measured amount of residual sulphite liquid to ultrafiltration by forced recirculation in a manner known per se, under certain conditions of pressure and temperature, on membranes adapted to the higher molecular weight of the fraction retained on the primary face of the membrane, a fraction which is then if a desired optimum concentration is reached, it is washed by a continuous supply of water for the separation of low molecular weight residual components, and 2) collecting the discharged filtrate on the secondary face of the membrane, to serve as a raw material for the recovery of fractions that have low molecular weight, by reverse osmosis during forced recirculation is indicated in 1), and using membranes having successively finer porosity, after which, if desired, the retained fractions are washed with water as indicated in 1).
