A distillation device and method of manufacturing a distillation device is disclosed. The distillation device includes at least one spiral wound membrane distillation (MD) unit. The spiral wound MD unit includes a perforated center tube concentric to a cylindrical housing and a plurality of effects spirally wound around the center tube. Each of the effects include a vapor permeable membrane, a feed spacer disposed on the vapor permeable membrane, a permeate spacer, and a heat exchange film. The permeate spacer is disposed between the vapor permeable membrane and the heat exchange film. Distillation of a feed fluid by the plurality of effects deposits a condensate fluid into the center tube.
