Abstract
A water treating apparatus is provided with a softening section, including an ion-exchange resin-filled section and a softening section disposed integrally with a vacuum deaerating membrane section so as to allow gases to pass through the membrane while a liquid is prevented from passing therethrough. The apparatus is compact in size and easily handled. The softened water provided thereby is useful as deionized and degassed water for boiler water and for the preparation of integrated circuits.
