ABSTRACT:
A method of reducing foaming of a liquid containing dissolved carbon dioxide during filtering. The carbonated liquid to be filtered is adjusted in pH to a value of 6.5 to 8.0 by the addition of an alkaline material which reacts with the dissolved carbon dioxide to remove the carbon dioxide from solution. The elimination of the dissolved carbon dioxide results in decreasing foaming during filtering and substantially increases the rate of filtration.
