    摘要: The disclosure relates to a separation process. An aerated inlet mixture of fluid and solids is fed to a flotation separation vessel and is separated into an upper float layer and a lower clarified layer. The upper float layer is withdrawn from the vessel when the height of the upper float layer exceeds the height of an overflow conduit and forms a concentrated solids effluent The lower clarified layer is withdrawn from the separation vessel as a clarified fluid effluent. The separation process is performed continuously using a control process that maintains a relatively stable distribution between the lower clarified layer and the upper float layer. The control process is a closed loop process that monitors the instantaneous height of the vessel contents and computes an error function based on the instantaneous height and a set-point height. The error function is used to periodically adjust the outlet flowrate of the clarified fluid effluent. The resulting process has improved stability (e.g., being continuously operable without interruption and/or operable for extended periods between intermittent cleaning processes) and provides a concentrated solids effluent with solids concentrations higher than those previously attainable in similar separation processes.

    摘要: A scalable process and device for producing a biomolecule, in particular pharmaceutical grade plasmid DNA is described. The process includes the steps of alkaline lysis, neutralization and clarification and can be further extended. For separating the lysate and the precipitate an improved floatation method is disclosed. This method is based on attachment of CO 2 bubbles on the precipitate floc. The CO 2 is released from a carbonate salt during or after neutralization (acidification). The method of the invention is preferably carried out in an automated continuous mode applying devices for lysis and neutralization and a novel device for completely continuous clarification (separation of flocs and clarified lysate).

    摘要: A coolant liquid feeding method comprises feeding a coolant liquid, with air bubbles caused to form continuously therein, for cutting or grinding operation to a region under machining, expediting the splashing of air bubbles in all directions when the air bubbles impinge on the region under machining and burst, and also expediting the entry of accelerated splashed liquid particles into a cutter/workpiece pressure contact plane, thereby improving the cooling and lubrication of the region under machining, whereby the air bubbles in the coolant liquid which has failed to reach the region under machining or which, though reaching there, has left there for the recovery channel are allowed to adhere to suspended foreign matters in the liquid, thereby expediting the surfacing of the foreign matters.
    The coolant liquid is discharged downward generally as a spiral flow which is a collection of particulate turbulent flows, thereby forming a cylindrical veil of coolant liquid which surrounds the milling tool or grinding tool and whose lower end reaches the surface of the workpiece, at least part of the spiral flow being caused to move from the lower end of the cylindrical veil along the surface of the workpiece in a whirl toward the central region until it is fed to the region under machining which is in contact with the milling tool or grinding tool.

    摘要: A flotation device for the suction of floated masses comprising a first inner tub (12) vertically arranged and communicating at the bottom with a second outer tub (26) which surrounds the first tub (12) and operates as a manifold for clarified liquid, the second tub communicating with a collector resevoir (34) for clarified liquid. At the middle of the first tub (12), the flotation device bears a column (40) extending above an upper edge of the inner tub (12) and sustaining a support (42) for a motorized arm (50) which can be oriented and ending with a suction hood (54) which can also be oriented by driving means (66) arranged on the arm (50); the column (40), the arm (50) and the suction hood (50) being hollow, connected among them and to a pipe (68) for the draining of floated particles. The pipe (68) is connected to a reverseble volumetric pump (70) which provides both for the removal of the floated particles and for the inlet of washing water in order to carry out periodic cleaning of the same flotation device.
