摘要： This invention relates to a process for the controlled flocculating or precipitating of foreign substances from a liquid by the addition of a flocculating agent, at least a partial quantity of the liquid being treated with a dosed amount of the flocculating agent, the flocculation or precipitation caused thereby in said partial quantity being measured by a turbidity measurement and the addition of the flocculating agent to the liquid to be treated being determined on basis of the turbidity measurement. An apparatus for the carrying out of such a process also constitutes the object of this invention.

摘要： The invention relates to a flotation method and a flotation reactor. The invention provides a method and a device, wherein the formation of the gas bubbles needed for flotation are produced by catalytic reaction of a chemical substance, i.e. H2O2, thereby saving energy and reducing the number of compressors. Flocculation also occurs in a tangential flow in the funnel-shaped expansion (12) of an admission pipe (8) so that a flocculation basin with a stirrer is no longer required.

摘要： The coalescence and release of bubbles from packing that supports the growth of microorganisms is promoted by mechanical action on the packed bed arrangement, in particular by continuous or intermittent vibrations, rotations, or by rocking motions. With particular advantage, a reactor vessel which is typically tubular is filled with packing upon which microbial growth is sustained, preferably leaving a free space of 10% to 35%, in particular 15% to 20%. The reactor vessel has an axis that is substantially horizontal but preferably inclined by at least about 3.degree., and is set continuously or intermittently, for example, by an axle drive or by means of friction wheel drive, into rotational or rocking motions about that axis. The gas can be discharged, for example, via valves and a cam mechanism. Alternatively, a vent pipe, taken through the hollow shaft on the discharge side and upwards, can be provided behind a screen plate. Pipes that are parallel to the axis and that have openings, which are protected by finlike rims with slots, feed liquid or gas to the biomass-containing system in the reaction vessel. In another embodiment, a vertical reactor is equipped with packing provided on vibrating plates which are set into vibration, preferably intermittently. For denitrification, a nitrate-nitrite degradation stage can be provided upstream of the reactor vessel.

摘要： An aeration/flotation reactor, of particular usefulness in the treatment of biomass-containing liquids, comprises a foam tube which terminates at the top in a collecting vessel and overlaps, or is inverted over, an inner rising tube which is preferably coaxial. The latter tube delimits an inlet chamber positioned, at the bottom of the foam tube, to receive liquid and finely divided gas bubbles. The lower end of the foam tube is enlarged, preferably into a funnel-shape, and runs into the lower region of an outer tube, the upper end of which is connected, via a return tube, to the inlet chamber below the axial rising tube. The outer tube, which is open at the top, is provided with a T-shaped liquid outlet having a dip connector, which extends below the liquid level, and with an outlet level immediately above the junction of the return tube, The upper end of the foam tube can be extended telescopically, thus permitting adaptation of the device to liquid/gas systems characterized by different foam properties.

摘要： A flotation method in which the gas bubbles for inducing flotation of the solids in the liquid are produced by a chemical reaction, for example a decomposition of hydrogen peroxide to oxygen and water, induced by catalytic action. The catalyst is on the walls of the flotation reaction and the substance to be flotated is introduced tangentially and caused to flow downwardly and thus upwardly in the reactor.
