Abstract:
A method of remediating a water-based fluid includes the steps of providing a container providing a fluid cavity and organic, inorganic and biological remediation media within the cavity. The container is tubular and provides a linear flow direction, organic, inorganic and biological remediation media arranged in the cavity and configured to permit a water-based fluid within the cavity to simultaneously flow through the media. The organic, the inorganic and the biological remediation media are respectively configured to remove organic, inorganic and microbiological constituents. The organic, inorganic and biological remediation media are arranged within the cavity along the linear flow direction. Multiple cartridges are arranged within the cavity and spaced apart from one another. A predetermined flow rate of the water-based fluid through the cavity is set and it concurrently removes organic, inorganic and iodine-based biocide contaminants from the fluid within the cavity.
Abstract:
The present invention provides a new design for high capacity stationary phases for chromatography, for example, ion chromatography. The stationary phases include a first polymer layer in contact with and at least partially coating the substrate of the stationary phase. The first polymer layer serves as a foundation for the attachment, and in various embodiments, the growth and attachment, of a highly hyperbranched polymer structure, typically based on one or more products of condensation polymerization. Multiple components are of use in forming the first polymer layer and the hyperbranched polymer structure, thereby providing a stationary phase that can be engineered to have a desired property such as ion capacity, ion selectivity, and the like. Exemplary condensation polymers are formed by the reaction of at least one polyfunctional compound with at least one compound of complimentary reactivity, e.g., a nucleophilic polyfunctional compound reacting with an electrophilic compound.
Abstract:
A device is provided for performing chemical transformation in a fluid, with a flow distributor having at least one fluid medium inlet, at least one fluid medium outlet, and at least one confinement wherein the chemical transformation is performed; and a means for rotating, rocking, wagging, or oscillating the device. At least one confinement may be equipped with a provision for providing heat, cooling, sound, light or other types of radiation, such provision being contacted to an external source through an actuator shaft. The flow distributor may be provided with sectors connected with the centrally located fluid medium inlet and a designated peripheral fluid medium outlet. The means for rotating, rocking, wagging, or oscillating the device may be an element producing magnetic fields or a shaft mechanically connected to an external actuating device.
Abstract:
A system for selectively removing at least one undesirable ion from an acidic solution including a tank receiving the acidic solution, a chiller in fluid communication with the tank, the chiller being configured to reduce a temperature of the acidic solution, and an ion exchanger in fluid communication with the chiller, the ion exchanger including an ion exchange resin that is selective for the undesirable ion.
Abstract:
An improved system for transferring heat, utilizing diols, specifically 1,3-propanediol (PDO). The system reduces the energy consumption, maintenance costs, corrosion, toxicity, and the risk of fire associated with such heat-dependent processes. Unlike traditional hydrocarbon heating fluids, diols do not require draining and replacement if a purifier is installed in the system. Business methods are also disclosed.
Abstract:
An ion adsorption module comprises a container with at least an opening into which feed water flows, and an organic porous ion exchange material having a three-dimensional reticular structure filled into the container, which has a continuous pore structure comprising macropores and mesopores, the macropores being interconnected with each other forming mesopores with an average diameter of 1-1,000 μm in the interconnected parts, has a total pore volume of 1-50 ml/g, contains uniformly distributed ion exchange groups, and has an ion exchange capacity of 0.5 mg equivalent/g or more of the porous material on a dry basis. The ion adsorption module can be extremely easily filled with the ion exchange material, and the packed layer does not move even if the layer is placed in an upward flow. The ion adsorption module and the water processing method using the ion exchange material are extremely useful.

Abstract:
A method for varying the capacity for a specific chemical element of an ion exchanger used for cleaning a liquid from a loop includes varying the chemical status of the element in the liquid to be cleaned immediately upstream of the ion exchanger by adding given substances. The given substances added are removed immediately downstream of the ion exchanger. The chemical element may be antimony, the loop may be the primary loop of a pressurized water reactor plant and the liquid may be primary coolant.
