Drinking water production through absorption of air humidity

The aim of this project is to develop and experimentally test an energy-efficient mobile distillation unit that can be used to produce drinking water by absorbing moisture from the ambient air. In the process, a highly hygroscopic lithium chloride brine removes part of the water vapor from the air flow via sorption elements and is distilled in a vapour compressor in a next step. This cooperation project with DEWA Engineering und Anlagenbau GmbH is financially supported by the Central Innovation Program for SMEs (ZIM) of the Federal Ministry of Economics and Technology. The cooperating company DEWA is responsible for manufacturing the plant. The measurements and process simulation models for the design and optimization of the plant are carried out at ITM.
