    • Method and system for processing of a liquid (“contaminant liquid”) containing water and containing urine and/or other contaminants in a two step process. Urine, or a contaminated liquid similar to and/or containing urine and thus having a relatively high salt and urea content is passed through an activated carbon filter to provide a resulting liquid, to remove most of the organic molecules. The resulting liquid is passed through a semipermeable membrane from a membrane first side to a membrane second side, where a fortified drink having a lower water concentration (higher osmotic potential) than the resulting liquid is positioned. Osmotic pressure differential causes the water, but not most of the remaining inorganic (salts) contaminant(s) to pass through the membrane to the fortified drink. Optionally, the resulting liquid is allowed to precipitate additional organic molecules before passage through the membrane.
    • 在两步法中处理含有水并含有尿和/或其他污染物的液体(“污染液体”)的方法和系统。 尿液或类似于和/或含有尿液并因此具有相对高的盐和尿素含量的污染液体通过活性炭过滤器以提供所得液体以除去大部分有机分子。 所得液体通过半透膜从膜第一侧到膜第二侧,其中定位具有比所得液体更低的水浓度(更高的渗透势)的强化饮料。 渗透压差导致水,但绝大多数剩余的无机(盐)污染物通过膜到强化饮料。 任选地,使所得液体在通过膜之前沉淀另外的有机分子。
