Water clarification method and device

An apparatus for clarifying liquid or sludge comprising organic material and water, the apparatus comprising:

• first pumping means configured to pump, at a minimum rate of QEB and via at least a first inlet of a reactor that is closed and has a predetermined volume v, a continuous flow of the liquid or the sludge into the reactor, wherein the first inlet is between a top of the reactor and a bottom of the reactor, wherein the minimum rate of QEB is equal to VEB/hour, wherein VEB is at least 20 v,
• second pumping means configured to pump, at a rate d and via at least a second inlet of the reactor, air into the reactor,
• wherein the reactor comprises an outlet that has a cross section more limited than that of the reactor, said outlet being provided with a pressure regulating means for regulating pressure in the reactor, the pressure regulating means being arranged with the first inlet and the second inlet to:
• put the reactor in overpressure in relation to atmospheric pressure,
• produce, in the reactor by turbulent mixing of the liquid or the sludge with the air to cause treatment of colloidal structures present in the liquid or the sludge, a mixture of the organic material and a portion of the air that is in suspension with the water, and
• discharge, via the outlet, at least a portion of the mixture.

An apparatus for clarifying liquid or sludge that includes water, the apparatus comprising:

• a reactor defining a closed chamber and having a predetermined volume v, wherein the reactor has a first end, a second end, and a chamber body portion that extends between the first end and the second end along an axis, wherein the reactor has at least a first inlet configured to introduce a continuous flow of the liquid or the sludge into the closed chamber, and wherein the reactor has a second inlet configured to introduce air into the closed chamber;
• a first pumping means configured to pump, at a minimum rate of QEB, the continuous flow into the closed chamber, wherein the minimum rate QEB is equal to VEB/hour, wherein VEB is at least 20 v;
• and
• a second pumping means configured to pump, at a rate d, the air into the closed chamber simultaneously with the continuous flow;
• wherein the first end is configured with an outlet that has a cross section more limited than that of the reactor, wherein the outlet is provided with a pressure regulating means for regulating pressure in the closed chamber, wherein the outlet includes a tube portion configured to discharge from the reactor along the axis, and
• wherein the closed chamber, the first pumping means, the second pumping means, and the pressure regulating means are arranged to
• put the closed chamber in overpressure in relation to atmospheric pressure,
• generate, based on the simultaneous pumping of the continuous flow and the air into the closed chamber, a turbulent mixing of the liquid or the sludge with the air, wherein the turbulent mixing obtains a mixture of organic material and a portion of the air that is in suspension with water and is sufficient to cause treatment of colloidal structures present in the liquid or the sludge,
• circulate the mixture to the outlet, and
• discharge, via the tube portion of the outlet and along the axis, at least a portion of the mixture.
