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.

Metastable state spore incubation mixing systems are described. An example system includes a spores container to store spores, a nutrient container to store nutrients, a water supply line, a syringe tank, a syringe pump, an adjustable valve, a heater, and a controller. In a drawing phase of the system, a controller can cause the syringe pump and the adjustable valve to draw into the syringe tank a volume of spores, nutrients, and water to form a mixture. The controller causes the heater to heat the mixture for a period of time. In a dispensing phase of the system, the controller can cause the syringe pump to expel the mixture through the adjustable valve and into a water distribution system. The controller can direct the system through a number of other phases of operation.

The invention relates to a dispersion tool (4) that can be cleaned more easily. For this purpose, the dispersion rotor (8) is arranged on the dispersion tool (4) axially moveable between the working position in the shaft tube (5) and the cleaning position outside the shaft tube (5), the dispersion rotor (8), in the cleaning position, being preferably completely arranged outside the shaft tube (5) and therefore being more easily cleanable.

Provided herein are methods and systems of the invention that include the use of an automated solution dispenser to form a solution according to at least one target characteristic. A controller may be operatively connected to the automated solution dispenser, wherein the controller is programmed to direct mixing of one or more solids and one or more liquids to produce the solution. At least a portion of the solution can be dispensed into one or more containers.

Devices, systems, and apparatuses for heating a liquid are disclosed herein. In one embodiment, a heater includes a base comprising a generally planar surface and at least two heater pillars and a sensor pillar configured on the base. The at least two heater pillars each comprise heating elements. The sensor pillar includes a thermal sensor. A mixing element is configured on the generally planar surface of the base and is coupled to a mixing motor. When powered, the heating elements of the heater pillars are configured to generate heat and the mixing motor is configured to cause the mixing element to rotate.

Methods and systems for chromatography are disclosed that employ a flexible container configured to fit within a support structure and adapted to receive a filtration or absorptive medium. The flexible container can include at least one inlet, at least one outlet, and a separation barrier peripherally sealed within the container to separate the container into a resin containing portion and a drainage portion. The barrier can be configured to exclude the resin material from the drainage portion while allowing fluids to pass therethrough. The disposable chromatography system can further include one or more agitators disposed within the flexible container and adjustably configured to be raised or lowered in the flexible container. When the agitator is in the raised position, the resin packing material can operate in a settled, packed-bed configuration. Alternatively, the agitator in the lowered position permits the chromatography resin packing material to operate in a mixed, slurry configuration.

The embodied invention is a low humidity generator which encapsulates essential piping, pressure regulator, flow regulator, and saturator in a sealed vacuum chamber. Additionally, a Stirling piston type cooler is used to cool the saturator. This eliminates atmospheric water vapor permeation and the need for thermal insulation surrounding the piping and control units. Also, the humidity generator has improved cool down characteristics, improved thermal control, and better maintenance access.

A continuous ready mix joint or texture compound manufacturing system and a method for continuously manufacturing a ready mix joint or texture compound includes a continuous mixer having an inlet and an outlet, a pump disposed at the outlet of the continuous mixer, and a disperger having an inlet and an outlet. The continuous mixer is adapted to receive at least one dry ingredient and at least one wet ingredient at the inlet and continuously mix the at least one dry ingredient and the at least one wet ingredient to form a mixed composition. The pump is adapted to pump the mixed composition from the outlet of the continuous mixer to the inlet of the disperger. The disperger is adapted to receive the mixed composition and apply a shear force to the mixed composition to form a homogenized, disperged composition.

A domestic beverage carbonator for carbonating a liquid in a bottle comprising temperature and pressure sensors that communicate with processor to improve the carbonation process. The device further comprises a CO2 cylinder coupling and a cylinder discharge valve, an exhaust valve, a fill head and a user interface. The user interface further comprises user controls and a graphic display and the fill head has a pressure sensor to sense a pressure in the attached bottle and communicate a pressure signal to the processor and the processor uses the pressure signal to regulate the cylinder valve and the exhaust valve.

In a centrifugal mixer, a maximum wetting height within a mixing cup is optically detected and is regulated by means of a control of drives.
