Abstract
Ozone is dispersed in river water to be purified and used in a high pressure boiler. The ozone selectively degrades large organic molecules, dissolved in the water, which ordinarily will irreversibly foul the strongly basic anion attracting resin used to adsorb silicious contaminants from the water. The degraded molecules are reduced in resin-fouling capability and are removed from the resin during regeneration.
