  • Publication number: 20140014586
    Abstract: The present invention provides systems and methods for removing an oxidizable target contaminant from a fluid, and methods for their use. In embodiments, these systems and methods include an oxidizing agent, wherein adding the oxidizing agent to the oxidizable target contaminant forms an oxidized species that precipitates as an insoluble precipitate in the fluid; a substrate that forms a removable complex with the insoluble precipitate, thereby sequestering the oxidizable contaminant, and a removal system for removing the removable complex from the fluid.

  • Publication number: 20140008301
    Abstract: Method and apparatus for removing high density particles from a biological fluid such as blood using aphaeresis. The particles are preferably sub-micron in size and denser than normally occurring components of the fluid and can be removed by a modified reverse-flow gradient density centrifuge without damaging the fluid. The particles can be provided to a patient in vivo or added to the fluid after it is removed from the patient. Some particles can carry and deliver oxygen and scavenge carbon dioxide. Other particles are conjugated to capture molecules for attaching to targets such as cancer cells, viruses, pathogens, toxins, or excess concentrations of a drug or element in the fluid. The targets are then removed from the fluid along with the particles by the aphaeresis instrument.

  • Publication number: 20130161264
    Abstract: A method and system for processing fluoride-containing wastewater includes treating the wastewater with brine (waste) created by the regeneration process implemented by in ion exchanging water softener. The brine, which is typically disposed of, contains both calcium and magnesium salts, in varying concentrations and ratios. The regeneration process brine is added to the fluoride-containing wastewater within a reaction tank, and the fluoride ion concentration is monitored. When the fluoride ion concentration falls below a predetermined level (e.g., 15 ppm), the flow of regeneration process brine is stopped. A pH controller monitors the pH within the reaction tank, and adds a basic agent to ensure that the pH remains above a predetermined level (e.g., pH>9). The pH control results in a clear effluent, and a sludge having a high settling rate and a high dewater ability.

    Abstract: A mobile water treatment system is disposed on a trailer of a truck. There is an intake filter, an intake hose, a pump or multiple pumps for water intake and sending water throughout the system, a filtering section that may include sand and/or bag filter or other types of filters, an ozone treatment section after the filters, a holding tank after the ozone section, a UV treatment section after the holding tank, and a chlorination tank. The water may then be sent to a water storage facility or other place as desired. The system includes a generator for power to run the system, and a controller for the system. The ozone section makes use of a misting nozzle in order to increase ozone contact time, and decrease ozone breakdown. The UV section makes use of a slightly downward tilted table with UV bulbs and reflectors above it, and preferably is mounted on a leveling system. A method of treating water uses the mobile system.

  • Publication number: 20130048547
    Abstract: Provided is a filtration system for filtering contaminants and impurities from a coolant, such as water, applied to an air conditioner unit for cooling the air conditioning unit to increase the efficiency thereof. The filtration system filters the coolant to achieve a desired purity level to allow the coolant to mitigate corrosion or particle buildup on the air conditioning unit when the coolant is applied thereto. Along these lines, if the purity level is too low, the contaminants present in the coolant may corrode the air conditioning unit. Conversely, if the purity level is too high, the coolant itself may react with the air conditioning unit, which may lead to corrosion or other structural issues. Thus, the filtration system is specifically configured and adapted to purify the coolant to achieve a purity level within a desirable purity range.
