Beschreibung
Zusammenfassung:	Processes for the preparation, concentration and recovery an N-(phosphonomethyl)glycine product from aqueous process streams including contacting mother liquor generated in the precipitation of N-(phosphonomethyl)glycine product crystals with a selective membrane to produce a retentate enriched N-(phosphonomethyl)glycine product and a permeate depleted in N-(phosphonomethyl)glycine product are disclosed.
