Abstract
Oliver processing brines containing 0.05 to 0.7% sodium chloride were passed through a mixed bed of cation and anion exchange resins in a process known as the Aqua-Ion process. Influent pH, salt content, and COD levels were the particular variables of interest investigated. Sodium chloride levels of 500 to 7000 ppm were subjected to random variations in pH and COD levels, with 94% removal being obtained at 2700 ppm, the optimum for the ranges investigated. Holding pH and COD constant, sodium chloride levels were varied between 600 and 6000 ppm, with resulting effluent concentrations of 150 ppm for influent concentrations of 600, 1000, and 2700 ppm. Influent concentration of 6000 ppm resulted in an effluent concentration of 790 ppm. Calcium hydroxide regeneration was used, with the regenerant being repeatedly cycled through the resin bed to establish the maximum salt concentration attainable in the regenerant effluent. Levels of 3000 ppm were obtained with no indication of leveling off. Pretreatment with activated carbon reduced distributor deposit formation, ennabling possible flow rates of 10,000 gpd. Cost analyses based on pilot plant information predicted a cost of 26 cents per 1000 gallons treated.
