Contents Notes
A number of extremely useful and widely produced compounds are produced by the alkaline hydrolysis of chlorohydrins such as ethylene and propylene glycols and glycerin. The brine wastewater resulting from the production of the glycols is characterized by a high salt content (8-10% NaCl), excess alkalinity, and the presence of several organic compounds. Several processes were examined in the laboratory to determine the usefulness for the treatment of the brine wastewater. The processes tried included solvent extraction of the glycol wastewater with secondary or tertiary amines; adsorption of glycols on activated carbon; biological oxidation of propylene glycol wastewater; and an activated sludge process. Only the last was successful. The operational and design parameters determined from a pilot plant operation were used to design an activated sludge plant to treat 6 MGD of wastewater resulting from the production of 1.2 million pounds per day of propylene glycol. Costs are given.
