Increasing oxygen transfer into aqueous solutions
Abstract
Abstract THE RATE AND EFFICIENCY OF OXYGEN TRANSFER INTO AQUEOUS SOLUTIONS IS INCREASED ACCORDING TO THE DISCLOSED METHOD BY FIRST SELECTING A WATER-IMMISCIBLE LIQUID HAVING THE PROPERTIES OF EITHER A GREATER SOLUBILITY FOR OXYGEN THAN HAS WATER OR, FOR AN EQUIVALENT AMOUNT OF ENERGY, ALLOWS A FASTER TRANSFER OF OXYGEN INTO THE LIQUID THAN IS TRANSFERRED INTO WATER UNDER SIMILAR CONDITIONS OR BOTH. THE LIQUID SELECTED IS THEN OXYGENATED, BROUGHT INTO CONTACT WITH AND DISPRESED THROUGHOUT THE AQUEOUS SOLUTION TO BE OXYGENATED AND THE OXYGEN PASSES FROM THE WATER-IMMISCIBLE LIQUID INTO THE AQUEOUS SOLUTION. THE WATER IMMISCIBLE LIQUID IS THEN SEPARATED FROM THE AQUEOUS SOLUTION AND OPTIONALLY RE-OXYGENATED AND REUSED. THE AQUEOUS LIQUID MAY COMPRISE A CHEMICAL SYSTEM OR A MICROBIOLOGICAL SYSTEM. THE METHOD IS USEFUL IN INCREASING THE OXYGEN SUPPLY NECESSARY TO SUPPORT AEROBIC MICROBIOLOGICAL FERMENTATIONS AS USED IN LIQUID WASTE TREATMENT PROCESSES.
