Abstract
Abstract Method and apparatus for increasing the oxygen content of water for sanitizing natural waters and for purifying water, in which method oxygen or oxygen containing gas is fed into water liberated from gases dissolved therein, characterized in that gases are separated by pressure strokes on the liquid and/or vibration whereafter the desired gas, e.g. air, oxygen or oxygen containing gas, is fed into the liquid.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
164 words
A method for increasing the oxygen content of water for sanitizing natural waters and for purifying water, in which method oxygen or oxygen containing gas is fed into water liberated from gases dissolved therein, characterized in that gases are separated by pressure strokes on the liquid and vibration whereafter oxygen or oxygen containing gas, is fed into the liquid, and water flowing along the suction pipe is set to vibrate by means of a vibrator; said water being discharged and noxious gases escaping from the water; said water being forced by means of a propeller pump and the resultant pressure developed in said water into a gas feed zone provided by dispersion means, said zone being connected to a source of gas through pipes, gas bubbles formed on wet surfaces of the dispersion means for dispersing said bubbles said bubbles being mixed with flowing water, said propeller pump forcing said water with gas bubbles into a discharge pipe and therealong to the desired depth.
Claim 2
Independent Claim
164 words
A method for increasing the oxygen content of water for sanitizing natural waters and for purifying water, in which method oxygen or oxygen containing gas is fed into water liberated from gases dissolved therein, characterized in that gases are separated by pressure strokes on the liquid and vibration whereafter oxygen or oxygen containing gas, is fed into the liquid, and water flowing along the suction pipe is set to vibrate by means of a vibrator; said water being discharged and noxious gases escaping from the water; said water being forced by means of a propeller pump and the resultant pressure developed in said water into a gas feed zone provided by dispersion means, said zone being connected to a source of gas through pipes, gas bubbles formed on wet surfaces of the dispersion means for dispersing said bubbles said bubbles being mixed with flowing water, said propeller pump forcing said water with gas bubbles into a discharge pipe and therealong to the desired depth.
Claim 3
Dependent Claim
16 words
