Membrane Distiller and Membrane Distillation Assembly Comprising Such Membrane Distiller

A membrane distiller for producing purified water, the membrane distiller comprising:

• an evaporation chamber,
• a condensation chamber, and
• a membrane separating the evaporation chamber and the condensation chamber from each other, wherein the membrane has a pore size equal to or less than 1000 nanometres,
• wherein the membrane is a multi-layer polymer membrane comprising a nonwoven first layer having a pore size equal to or less than 1000 nanometres and a spunbonded second layer that is laminated to the first layer, wherein the second layer is facing the condensation chamber, wherein the membrane distiller comprises a rigid first polymer frame having a first surface, a second surface and a central aperture extending between the first surface and the second surface, at least a portion of the condensation chamber being constituted by the central aperture, wherein the membrane is connected to the first surface of the first polymer frame covering the central aperture and the second layer of the membrane is facing the first surface of the first polymer frame, and in that the membrane distiller comprises a cooling chamber located adjacent the condensation chamber, wherein a polymer film separates the cooling chamber and the condensation chamber from each other.

A membrane distillation assembly for providing purified water, the membrane distillation assembly comprising,

• a membrane distiller that is configured for producing purified water, the membrane distiller having an evaporation chamber and a condensation chamber, wherein the evaporation chamber and the condensation chamber are separated from each other by a membrane, wherein the membrane has a pore size equal to or less than 1000 nanometres,
• a reservoir connected to the membrane distiller, the reservoir being configured for intermediate storing of purified water,
• a water supply unit connected to the membrane distiller, and
• a purified water dispenser tool connected to the reservoir,
• wherein the membrane is a multi-layer polymer membrane comprising a nonwoven first layer having a pore size equal to or less than 1000 nanometres and a spunbonded second layer that is laminated to the first layer, wherein the second layer is facing the condensation chamber, wherein the membrane distiller comprises a rigid first polymer frame having a first surface, a second surface and a central aperture extending between the first surface and the second surface, at least a portion of the condensation chamber being constituted by the central aperture, wherein the membrane is connected to the first surface of the first polymer frame covering the central aperture and the second layer of the membrane is facing the first surface of the first polymer frame, and in that the membrane distiller comprises a cooling chamber located adjacent the condensation chamber, wherein a polymer film separates the cooling chamber and the condensation chamber from each other.
