A wastewater treatment device has: an ozone generator which supplies ozone; a mixer which mixes ozone supplied from the ozone generator with wastewater and supplies ozone mixed wastewater; an ozone oxidation unit which progresses ozone oxidation in the ozone mixed wastewater while passing the ozone mixed wastewater therethrough and discharges wastewater in which the ozone has been consumed; a biological treatment unit which performs biological treatment on the wastewater discharged from the ozone oxidation unit using microorganisms; and an adjusting device which adjusts the amount of ozone to be mixed with the wastewater by the mixer so that ozone in an amount that inhibits the microorganisms of the biological treatment unit does not remain in the wastewater discharged from the ozone oxidation unit.

Disclosed herein is a device and method for changing the conditions of a solution flowing in a serial path. In particular, disclosed herein is a device that includes a chemical reactor, a first system, and a second system that are each serial to one another. Each of the first system and the second system include a mixing chamber, a solvent reservoir, a solvent pump, and one or more detectors. Also disclosed herein is a method for changing the condition of a solution that includes flowing a liquid sample in a path, serially mixing the sample with at least two discrete solvents while it flows through the path, and detecting the condition of the sample after it is mixed with each solvent.

A method and system for treating wastewater is disclosed. In one example the method comprises activating a mixing system that imparts a motive force on wastewater in a vessel, measuring at least one property of a first portion of the wastewater at a first time, measuring the at least one property of a second portion of the wastewater at a second time subsequent to the first time, calculating a difference between the at least one property measured at the first time and the at least one property measured at the second time, performing a determination of whether the difference is within a predetermined allowable range of differences, and responsive to a result of the determination, controlling a component of the mixing system.

A food processing facility having application apparatus located within the interior space of the food processing facility for applying a PAA solution to food, a mixing container for containing a PAA solution having a PAA solution concentration, with the mixing container connected to the application apparatus for delivering the PAA solution to the application apparatus, and a PAA gas sensor, located within the interior space, for sensing a PAA airborne concentration. An actuation control system connected to the PAA gas sensor is adapted to receive a measure of the PAA airborne concentration and, when the measure of the PAA airborne concentration exceeds a reference value, changes one or more of the PAA solution concentration of the PAA solution in the mixing container, the flow rate of the fresh air ventilation system, and the flow rate of the exhaust air system.

A novel in vitro system and method for predicting the in vivo behavior, such as absorption time or mechanical strength retention, of biodegradable polymeric implants and medical devices. Data from this in vitro method are correlated to in vivo absorption data, allowing for the prediction of accurate in vivo behaviors, such as absorption times. The system uses a novel bypass loop to maintain the integrity of pH measuring devices to improve the reproducibility of data collected during in vitro testing.

The present invention provides a method for the manufacture of a carbonated beverage, including the steps of: providing oxygen-reduced water; mixing the oxygen-reduced water with a mixing component to obtain a beverage mixture, adding a gas comprising CO.sub.2 to the beverage mixture to obtain a beverage mixture mixed with CO.sub.2, reducing the oxygen content of the beverage mixture mixed with CO.sub.2 in a first container to obtain an oxygen-reduced beverage mixture mixed with CO.sub.2, discharging the oxygen-reduced beverage mixture mixed with CO.sub.2 from the first container, determining the CO.sub.2 content of the oxygen-reduced beverage mixture mixed with CO.sub.2; and adding further CO.sub.2 to the discharged oxygen-reduced beverage mixture mixed with CO.sub.2 on the basis of the determined CO.sub.2 content to obtain a finally carbonated beverage.

A low-cost drug compounding system that can practically fit inside of a fume hood or the like is provided. The system can use a single pump operable in forward and reverse directions (or multiple pumps) to compound complex mixtures particularly including those requiring the creation of solutions from dry or powdered ingredients. A wireless link allows operation of the system remotely. In one embodiment, the system uses a disposable mixing tube set that can be discarded after mixing while still attached to the base ingredient containers used for the compounding thereby minimize the chance of personnel exposure.

The present invention relates to a device (60) for manufacturing pharmaceutical compositions, comprising: a support (62); a mixing container (16); a plurality of reservoirs (18, 20) containing starting materials for the composition of a medicament; at least one dispensing device (64, 66) that is designed to dispense an amount of a starting material into the mixing container, wherein the dispensing device is assembled, or is designed to be assembled, with a reservoir; a stirring device (68) that is able to stir the mixing container and/or the contents of the mixing container; and an electronic module (74) for controlling the at least one dispensing device.
