In the very brief study the removal with polyelectrolytes of both soluble organic and insoluble organic and inorganic materials is considered. Particular attention is given to the use of Primafloc C-7, a polyamine bisulfate salt which permits much greater removals to be attained than do other presently known cationic polyelectrolytes. Emphasis is placed upon the removal of soluble, anionic, organic foulants from aqueous streams. These materials are known to irreversibly foul conventional anion exchange resins. Economical removal of such anionic, organic foulants should increase considerably the useful life of such anion exchange resins.
