The invention pertains to a device for the condensation of water from an aqueous liquid by using a temperature gradient, which device includes: (a) a vapor chamber that can be brought in contact with a condensation compartment wherein at least part of the water vapor from the aqueous liquid condenses, and wherein inside of said vapor chamber is located (b) an evaporation compartment having a least a wall with an outer surface and which includes a closed, hollow and water permeable membrane wherein the vapor chamber has an outer surface that includes a substantially water-impermeable insulation skirt with an inner and an outer surface, such that there is a gap between the inner surface of the insulation skirt and the outer surface of the evaporation compartment, and wherein the vapor chamber has a lower surface of an active width (w) which is at least 10% of the effective diameter (d) of the evaporation compartment. The invention further pertains to a device and to the use of said device for the irrigation of plants, salt leaching, recovery of fresh water, purification of water by membrane distillation, and/or concentrating waste water.
