    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.
