Abstract:
A method of treating alkaline water comprises the steps of introducing water into a first compartment (1), bubbling carbon dioxide into the water in the first compartment (1), causing solids to precipitate, transferring water with solids that have precipitated into a second compartment (2), separating, in the second compartment (2), solids that have precipitated from the water, transferring water from which solids have been separated to a third compartment (3), bubbling carbon dioxide into the water in the third compartment to reduce the pH of the water, and removing water from the third compartment (3), the pH of the water removed from the third compartment (3) being lower than the pH of the water in the second compartment (2). The compartments are provided in a single portable unit.

Abstract:
Methods and systems for efficiently manufacturing modified asphalt materials include agitating a base asphalt at a high shear rate using an in-line mixer equipped with a rotor-stator mixing tool while simultaneously exposing the asphalt to oxygen by blowing an oxygen- containing gas at a high gas flow rate through openings in the rotor-stator mixing tool and heating the asphalt at an elevated temperature.
Abstract:
A surface aeration impeller incorporating a stabilizer cylinder that damps out and eliminates any sustained oscillatory or vibratory displacements normal to the axis of rotation when the impeller is in operation. The surface aeration design operates in a mechanically stable fashion under diverse loading conditions and at any static liquid level submergence of the impeller.
Abstract:
The invention relates to a stirring assembly comprising a stirring element (2) for stirring a liquid and a gassing device (3 or 3') which supplies gas, such as air, below the stirring element (2) and at the side(s) of the stirring element (2), with the gas to be dispersed by means of the stirring element (2). The gassing device (3; 3') is designed in such a manner that until a critical gas quantity value determining the flooding point is reached, the gassing device (3; 3') supplies the quantity of gas to the stirring element (2) from below and when the flooding point is exceeded, the gassing device (3; 3') simultaneously supplies the gas exceeding the flooding point at the side(s) of the stirring element (2). The aim of the invention is to prevent the stirring element (2) from being flooded and to improve the dispersing effect of the liquid and gas. For this purpose, the gas supply in the stirring assembly according to the invention is carried out, depending on the quantity of gas to be supplied, from below and from the side(s) in relation to the stirring element (2).

Abstract:
A wet type air cleaner includes a purification unit installed in a housing. The purification unit includes a blower unit for directing air to cleaning water in the bottom of the housing; an inner guide for drawing up the cleaning water in the bottom of the housing; a nozzle portion for dispersing radially the cleaning water drawn up by the inner guide, the air directed by the blower unit flowing through the dispersed cleaning water; and an outer guide for guiding the directed air and the dispersed cleaning water into the cleaning water in the bottom of the housing. The blower unit, the inner guide and the outer guide are together rotated by a driving unit. The inner guide has a central portion and a spiral guide portion disposed on an outer surface of the central portion.
Abstract:
A fermentation process uses substantially pure oxygen. The oxygen is the only reactive gas which is injected into a fermentation vessel. The oxygen is moved through the vessel solely by its own pressure. The process can be used with both mechanically-agitated and air-lifted fermenters. The mechanically-agitated fermenter includes an analyzer (35) for measuring oxygen concentration in the exhaust line, and adjusting the flow of fresh oxygen into the vessel accordingly. In the air-lifted fermenter, an analyzer measures the oxygen concentration in the head space of the vessel, and operates valves which either recycle the gas from the head space, or vent that gas to the outside, according to the measured concentration. A stream of nitrogen is periodically injected into the vessel to drive out carbon dioxide and other gases, to control the pH of the fermentation medium. The present invention substantially improves the efficiency of a commercial fermentation process.
Abstract:
A method and an apparatus (11) for treating fluids are provided. The method generally includes cavitating and irradiating a liquid. The irradiation of the liquid may include exposing the liquid to ultraviolet radiation. The apparatus generally includes a housing (12) having a chamber (15) formed therein and defined, at least in part, by a chamber wall that transmits radiation therethrough. The apparatus also includes a cavitator in flow communication with the interior of the chamber and a radiator (10) aligned to direct radiation into the interior of the chamber. Cavitation generated by the apparatus and/or provided in the method tends to refresh the liquid exposed to the radiation, thereby increasing the rate of radiation exposure for the liquid.
Abstract:
The invention provides an agitator (1) is disposed to agitate slurry within a flotation tank (2). The agitator includes a rotor (6) mounted on one end of a centrally disposed drive shaft (7) extending axially downwardly into the tank and driven by a motor (8) and associated gearbox (not shown). The other end of the drive shaft includes a mounting flange (9) adapted for connection to the motor. A stator (10) is also provided around the rotor. A froth deflection cone (11) extends around the drive shaft adjacent the top of the tank. The deflection cone is oriented such that its smallest diameter is located at its lowermost end nearest the rotor (6). An auxiliary agitator (12) is connected to the drive shaft at a position substantially midway between the underside of the deflection cone (11) and the top of the rotor (6), as shown in Figure 1 and Figure 2. The auxiliary agitator (12) includes agitation blades (13) extending radially outwardly from diametrically opposite sides of the shaft (7). Each blade (13) intersects the shaft at an angle of incidence of around 45 degrees to the shaft axis (14).
