摘要： The invention consists of a water treatment process using selective and regenerable weak base anion exchange resins to remove any number of complex anions, especially oxyanions including perchlorate, nitrate, chlorate, arsenate, selenate, and chromate, from aqueous solutions. The treatment process is comprised of three key processes including 1) pretreatment to lower pH, 2) ion exchange, and 3) post treatment to adjust pH and alkalinity. The invention also includes processes for regenerating weak base anion resins and treatment of the residuals generated. This invention employs pressurized treatment, carbon dioxide management, and reuse of regenerating solution to minimize pumping and treatment costs.

摘要： A new process for ion exchange softening of water used in Once-Through Steam Generators (OTSGs) by recovering and using the salt content of the blowdown water from the OTSG to regenerate the softener resin is provided, thus eliminating the cost for commercial regenerant salt that would otherwise be needed. Further, the very high purity of the salt recovered in the blowdown inherently results in the production of softened water with hardness leakage levels that are an order of magnitude lower than can be attained using commercial salt, thus reducing scale deposit potential and improving operating efficiency and reliability of the OTSG.

摘要： The present invention provides a method for purifying or softening water comprising: passing a specific volume of feedwater through at least one service column comprising a strong acid cationic exchange resin capable of binding divalent cations that are present in the feedwater, wherein the loading of the divalent cations on the resin is restricted to about 1 to 25% of the available ion exchange sites on the resin, and the total dissolved solids in the feedwater is greater than 100 mg/l; feeding the water exiting the service column to a reverse osmosis membrane or a nanofiltration membrane to produce permeate water stream and a reject water stream; and passing all or some of the volume of the reject stream corresponding the specific volume of feedwater through at least one off-line column capable of binding monovalent cations; wherein the chemical equivalent ratio of monovalent to divalent cations in the water exiting the service column is greater than 20 to 1; wherein no external source of regenerant salt is used. The inventive method allows for multiple softening/regeneration cycles so that steady state hardness leakage is achieved that is lower than obtainable with conventional ion exchange softening systems.
