| 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). | ||||||

A method and apparatus for feeding coolant liquid to a lathe with a nozzle (53) having a discharge port (58) of substantially rectangular cross section and a constricted curved surface portion (62) on its inner wall to produce a turbulent flow and a loosely mounted tongue piece (59) crossing the section of the discharge port and projecting outside the port. The coolant is thus discharged as a collection of particulate turbulent flows containing air bubbles drawn into the coolant liquid as it passes by the tongue piece. The coolant is caused to impinge on the rotating peripheral surface (56) which is continuous with the region of the workpiece in contact with the cutter (57). |

| A mobile apparatus and method for treating contaminated soil is disclosed. The apparatus consists of three interconnected subunits, namely a fluidized bed reactor (10, 200) for segregating an aqueous soil slurry based on particle size; a metals extraction unit for removing heavy metals and other contaminants from the contaminated soil fraction; and a water treatment system utilizing a high density sludge process to remove metals from the contaminated aqueous phase. The fluidized bed reactor (10, 200) includes a relatively small first chamber (12, 202) and a relatively large second chamber (14, 204) which are partially separated by a baffle (16, 206). Pressurized gas is dispersed into the first chamber (12, 202) to create a turbulent mixture of raw soil and water, resulting in interparticle scouring of the soil surfaces to assist in the abrasion and removal of adsorbed contaminants. The soil particles are segregated into a first fraction containing relatively small, contaminated soil particles and a second fraction containing relatively large, uncontaminated soil particles. The first fraction is preferably withdrawn from an upper portion of the reactor (10, 200) as a foam. A soil slurry containing the relatively uncontaminated second fraction is continuously withdrawn from a lower portion of the reactor (10, 200). In one embodiment of the invention, the soil slurry may be circulated between the first and second chambers multiple times to increase the soil residence time in the reactor (10, 200). The soil slurry is dewatered downstream of reactor (10, 200) and the water filtrate is recycled. Gas vented from reactor (10, 200) may also be captured, cleaned and recycled. | ||||||

| A compact dissolved-air-flotation (DAF) clarifier and clarification process utilize three zones for clarification which operate in sequence in a single clarifier. Raw water with suspended solids enters a flocculator at the center of an annular tank where microscopic air bubbles introduced to the inflow float flocked contaminants to form a floating sludge layer. A first clarification, calming and degassing occur here. The water then flows radially outwardly into the tank where further quiet clarification occurs. A third level of clarification occurs in a lower portion of the tank, specifically, in a set of plate-like lamellae, radial and conical, which form inclined channels where a final clarification occurs. The bottom wall of the tank has a set of apertures which allow a gravity flow of clarified water through a layer of pressurized gas to an underlying collection compartment. Level sensors control a valve in the clarified outflow line and an air bleed from the pressurized gas layer to regulate liquid levels in the clarifier. A set of rotating paddles push the sludge layer up a ramp to an inclined discharge conduit. Alternatively, a suction head with a mechanical skimmer sweeps around the tank to draw the sludge through a central hollow pipe to a discharge conduit. An offset drive operating through a belt rotates the sludge removal mechanism and the lamellae. | ||||||

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. |
