WASTE WATER TREATMENT Abstract of the Disclosure In order to dissolve in a liquid amounts of gas giving a relatively high concentration of gas in the liquid, it is usually necessary to pass into the liquid considerably more gas than is theoretically needed. This is because some of the gas will pass out of the liquid without dissolving and thus is wasted. This wastage is reduced by the present invention wherein, prior to the gas dissolving step, the liquid in which the gas is to be dissolved is subjected to a reduced pressure to release therefrom gases therein.
