More Information
Summary:Some embodiments may include a device for separating product water which is obtained by condensation from raw water comprising a mixture of water and impurities comprising: a gas process circuit for a process gas, including an evaporator for the raw water and a condenser for the product water connected in series; and a product water process circuit including the condenser and a first heat exchanger for cooling the product water connected in series. The evaporator comprises an inlet for the raw water and an outlet for a concentrate which as compared to the raw water has a higher concentration of impurities to be separated. The condenser comprises an inlet for the product water in a top of the condenser and the outlet for the product water in a bottom of the condenser. The process gas flows from the bottom of the condenser to the top of the condenser.
