Abstract: The invention provides an efficient method to purify an aqueous solution, typically mine drainage water, especially of anions and cations present in the aqueous solution as dissolved solids, the anions and cations are removed by treatment with a positively charged extractant having at least eight carbon atoms, whereby an unstable emulsion is formed; the unstable emulsion is allowed to break into an extract phase loaded with the anions and cations, and a water phase depleted in anions and cations; a floc inherently forms in the loaded extractant phase and then the loaded extractant phase and floc are separated from the purified water and treated to remove the anions and cations as concentrated useful products; the treated aqueous phase now reduced in anion and/or cation content is also separated from the emulsion as a purified aqueous solution. The extractant phase is preferably recycled. A continuous water purification process is provided.

Abstract: The invention provides an efficient method to treating a nutrient rich process water, such as municipal, agricultural, and/or farm water. The process water is treated by first extracting one or more P- and/or N-based ionic species from the process water with an extractant phase, resulting in an ion-loaded extractant phase; and then stripping one or more ionic species from the ion-loaded extractant phase to obtain a stripped extractant phase and useful concentrated ionic products. The stripped extractant phase is preferably recycled. A continuous flow treatment process is provided. The process is also capable of inactivating pathogens and reducing odors.
