SULFOCATIONITE REGENERATION METHOD Russian patent published in 2001 - IPC

Abstract RU 2166364 C1

FIELD: water treatment. SUBSTANCE: invention is intended for use in KU-2x8N sulfocationite regeneration process flow-sheets on power and heat stations and is distinguished by that regeneration is effected with 0.8-1.0% sulfuric acid in quantity 16-18 g acid (calculated for 100% sulfuric acid) per 1 g-equ of adsorbed cations. EFFECT: reduced acidity of regenerate to the extent allowing neutralization step to be avoided before discharge of water into sewer net. 1 tbl
