Abstract

The present invention relates to a method for cleaning water by means of RO equipment (2) where unclean water (10) is pre-treated. The invention is characterised in that the pre-treated unclean water (13) is caused to be led through a membrane distillation arrangement (1) on its cold side before the RO equipment (2), in that the concentrate (16) from the RO equipment (2) is caused to be heated, and in that the heated concentrate (16) is caused to be led through the membrane distillation arrangement (1) on its hot side.
