ABSTRACT:
The invention relates to an apparatus for removal of suspended matter from a liquid, such as used for treatment of oil containing water. A cylindrical horizontal vessel is divided into a single gasification chamber and a single degasification chamber by a partition which extends through the interior chamber of the vessel and allows fluid communication between the two chambers. A liquid to be treated is introduced through distribution header(s) adjacent a bottom of the vessel and/or an alternative inlet nozzle which is combined with a gas eductor in order to achieve a more intimate mixture of the gas and liquid. The gas eductor has its outlet slightly above the outlet of the distribution headers. The released gas bubbles carry oil and suspended matter towards the upper portion of the vessel, from which the froth is collected through a primary skim collection trough which extends through the gasification chamber and from a vertically adjustable, based on specific gravity, secondary skim collection funnel in the degasification chamber. Skim collection is accomplished through control of the liquid level in the vessel.
