    • A process for purifying water via freezing is disclosed. The process may include: contacting an aqueous mixture with a flotation medium, wherein the flotation medium has a density greater than or equal to the density of ice or hydrate and less than the density of the aqueous mixture or concentrated brine at its freezing point; reducing the temperature of the aqueous mixture to a temperature equal to or below the freezing point of the aqueous mixture to form ice or hydrate and a concentrate; phase separating the concentrate and the flotation medium; recovering the concentrate; and recovering the ice or hydrate and flotation medium as a slurry. Upon melting, phase separation of the resultant water from the flotation medium may provide a purified water product.

    • The invention relates to a method and arrangement for purifying water. The method utilizes two chambers (1, 2) and a closed air circuit arranged therebetween, to a fan (5) through two channels (3, 4). The method comprises the following steps: between the chambers (1, 2), there is arranged a temperature difference, so that the temperature in the first chamber (1) is higher than the temperature in the second chamber (2), raw water (RW) is sprayed in the first chamber (1), a first air flow (A1) is brought in the first chamber (1) and in contact with the sprayed raw water (RW1), a humidified second air flow (A2) is conducted in the second chamber (2), and at least part of the humidity of the second air flow (A2) is condensed in the second chamber (2) and recovered as pure water, so that the humidity of the first air flow (A1) leaving the second chamber (2) is reduced, the first air flow (A1) is conducted from the second chamber (2) to the first chamber (1), and the above described steps are repeated. According to the invention, the method also includes the following steps: raw water (RW) is heated by a heating device (18) outside the first chamber (1) and sprayed essentially in tiny droplets to the first chamber (1) by means of sprinkler equipment (6), the temperature difference between the chambers is maintained by thermally insulating (16) at least one of the chambers (1, 2), and raw water droplets are removed from the humidified second air flow (A2) by a droplet separator (8) before it enters the second chamber (2).
    • 本发明涉及一种净化水的方法和装置。 该方法利用两个腔室(1,2)和设置在其间的封闭空气回路通过两个通道(3,4)与风扇(5)连接。 该方法包括以下步骤:在腔室(1,2)之间布置有温度差,使得第一腔室(1)中的温度高于第二腔室(2)中的温度,原水 RW)喷射到第一室(1)中,第一空气流(A1)被引入第一室(1)并与喷射的原水(RW1)接触,进行加湿的第二空气流(A2) 在第二室(2)中,并且第二空气流(A2)的湿度的至少一部分在第二室(2)中冷凝并作为纯水回收,使得第一空气流(A1)的湿度 离开第二室(2)减少,第一空气流(A1)从第二室(2)传导到第一室(1),并且重复上述步骤。 根据本发明,该方法还包括以下步骤:原水(RW)由第一室(1)外部的加热装置(18)加热,并以微小的液滴喷射到第一室(1),借助于 喷淋设备(6)通过将至少一个室(1,2)热绝缘(16)来维持室之间的温差,并且通过液滴从加湿的第二空气流(A2)中除去原始水滴 分离器(8)在其进入第二室(2)之前。
