<p>Fluid mixtures containing a carrying liquid as water and solid particles or oil, or both may be separated in a settling treatment by being passed through channels between plates which are tilted so that one side of all plates is lower than the other, whereby the more dense phase concentrates on the lower side to discharge therefrom as a stream containing at least most of the solid particles, if that represents the more dense phase; and clear water discharges substantially free of particles from the upper side of the channels. While accomplishing the separation of phases the process may simultaneously and rapidly destroy organic materials in waste liquors, such as sewage waters, by utilizing an oxidation depending on (a) pressure treatment to supply more oxygen in solution from air and/or oxygen that is obtainable under atmospheric pressure, (b) the utilization of this oxygen to supply BOD and COD in the liquid, due to strictly chemical, enzymatic, and/or aerobic reactions, (c) the depressurization to eliminate dissolved gases, and (d) the continuation of these steps to obtain less polluted effluent water.</p> |
