Abstract: A liquid degasification apparatus having a vortex chamber of conical configuration with fixed internal grooves arranged in a spiral pattern along with means of controlling the amount of entering liquid, the pressure within said vortex chamber, and the amounts of both the products of the degasification process and contaminated liquid to be discharged to waste. A centrifugal impeller of open design imparts a rotary motion to the liquid to create a vortex in the vortex chamber and the dynamic force to convey the degasified liquid to its ultimate point of use. An adjustable stripping means causes the products of the degasification process along with quantities of the contaminated liquid to be directed to a rotating impeller of closed design, having as its primary function, the discharge of the contaminant products to waste.
