Abstract

Provided herein is an apparatus for producing dialysis fluid including a forward osmosis unit used for diluting a dialysis concentrate for producing dialysis fluid. The FO-unit includes a FO-membrane that separates a first side from a second side. The apparatus also comprises a first flow path including a first side and a control arrangement providing priming fluid from a source to the first flow path. A return path fluidly connects an inlet port of the first side to an outlet port of the first side to allow priming fluid from the outlet port to circulate to the inlet port via the return path. The apparatus further comprises a gas collection chamber arranged in the first flow path between the first side and the return path. The gas collection chamber removes gas from first flow path. The present disclosure also relates to a method for priming a FO-unit.
