Abstract: Waste waters are purified from metals, esp. low concns. of metal cations and anion-active metal complexes, by passing consecutively through an anion exchanger in sulphate form as well as through a cation exchanger in Na from. Waste waters contg. metal complexes, esp. Cu, Cu salts and Cu-EDTA, can be purified sufficiently for discharge into sewer system.

Abstract: Nitrocresols recovered in acetone, dioxane or tetrahydrofuran as washings from ion-exchangers is acidified and the organic solvent distilled off when the nitrocresol collects as an oil. Specifications 867,449 and 885,717 are referred to.ALSO:Ion exchangers used for removing nitrocresols from waste liquors are regenerated with mineral acids and acetone, dioxane or tetrahydrofuran. Specifications 867,449 and 885,717 are referred to.

Abstract: A system for removing long-chain and short-chain per- and polyfluoroalkyl substances (PFAS) from contaminated water using a regenerable anion exchange resin includes at least one first anion exchange resin vessel configured to receive a flow of water contaminated with long and short-chain PFAS compounds. The at least one first anion exchange resin vessel includes a first regenerable anion exchange resin therein having a high affinity for long-chain PFAS compounds configured such that a majority of the long-chain PFAS compounds sorb to the first regenerable anion exchange resin to remove a majority of the long-chain PFAS compounds from the contaminated water and produce a flow of water having a majority of the long-chain PFAS compounds removed. The system also include at least one second anion exchange resin vessel configured to receive the flow of water having a majority of the long-chain PFAS compounds removed.
