  • Patent number: 11066317
    Abstract: A process to remove nitrates and chrome from water. The process includes the steps of passing incoming nitrate and chrome contaminated water through a nanofiltration membrane. Retentate liquid rejected from the nanofiltration membrane is pumped to effluent or returned to the nanofiltration membrane. Permeate from the nanofiltration membrane is sprayed through a well screen upper collector above an open atmospheric bed having strong base ion exchange resin. The permeate is pumped through the ion exchange resin and through a gravel layer beneath the resin. The strong base ion exchange resin is periodically regenerated.

  • Patent number: 10183240
    Abstract: Systems, devices, and methods for providing nutrient removals in an up flow filtration storm water system for treating water to very high clean levels using filtration media. A filtration media supported by a screen above an angled floor in a vault allows for incoming storm water to pass into a void space above the angled floor into the screen and filtration media and then out an outlet to the vault. The filtration media can include recyclable and/or natural particles. Layers of river rocks can be placed on top of and below the filtration media. Water sprayers can further liquefy sediment and debris that fills the void space between the angled floor and the bottom of the screen. The captured debris can slide down the angled floor, where a vacuum hose from an above ground vacuum truck can remove the debris and sediment. The long lasting filtration media can be cleaned by being backwashed.

  • Publication number: 20140263009
    Abstract: A sustainable Low Water Footprint Re-circulating Aquatic System for cultivating aquatic organisms and plants. The system conserves water and energy by using gravity to move water and nutrients from the clarifier into the low water footprint management system. The novel water management system controls the volume of water in the plant grow bed such that it never rises to or above the surface, limiting evaporative water loss. Water flow to the plant grow bed is intermittent and the water management system retains water within the grow bed by capillary action, even when there is no water input. The grow bed contains microflora that convert nitrogenous wastes produced by the aquatic organisms to nitrogenous compounds useable by the plants. The clarified water is then pumped back into the animal tanks. The system is sustainable, cost effective, and highly productive, and uses 50-80% less water than conventional re-circulating aquatic production system.

  • Patent number: 8066874
    Abstract: An apparatus for treating an aqueous solution containing arsenic. The apparatus comprises a container that includes a housing, an inlet located at a first end of the housing and an outlet located at a second end opposite the first end. An outer wall extends between the first and second ends and enclosing a fluid flow path between the inlet and the outlet and an arsenic fixing agent is disposed in the fluid flow path. The arsenic fixing agent can include an insoluble rare earth-containing compound, more specifically, a compound comprising one or more of cerium, lanthanum, or praseodymium. The inlet and the outlet are adapted to be closed during transport and storage. The container is adapted to be sealed for long term disposal after exposure to an aqueous solution containing arsenic.

  • Patent number: 8029680
    Abstract: A filtration apparatus and a filtration method are provided. The filtration apparatus includes a filter medium, a first filter layer of a first filter aid disposed on an upstream side of the filter medium, and a second filter layer of a second filter aid disposed on an upstream side of the first filter layer. The first filter aid has a particle size distribution primarily including coarse particles, a representative particle diameter of which is smaller than a representative dimension of openings in the filter medium. The first aid forms bridges over the openings. The second filter aid has a particle size distribution primarily including fine particles, which are smaller than the first filter aid and which themselves cannot form bridges over the openings. The openings of the filter medium and the particles of the second filter layer are adjusted in size by bridging phenomenon of the first filter aid.

  • Patent number: 8002974
    Abstract: A stormwater inlet near an upper edge of a layered filter media vessel is equipped with a distribution header that ensures effective use of the surface area of the filter media by providing plural spaced streams of stormwater thereat, each at a point of impact having its energy dissipated by a layer of material that covers the upper layered filter media surface. The stormwater inflow is metered to control the stormwater pollutant removal process kinetics, thereby slowing the mean free path of the stormwater therethrough and optimizing pollutant capture. The water level within the vessel is height adjustable manually by a pivot arm in the form of a standing column of water coupled to the water within the container. Weep conduits are provided to slowly drain down the standing water in the system between storm events, simplifying maintenance and promoting best removal of pollutants from first-flush storm events. Stormwater pretreatment, e.g. by use of an oleophilic agent or a pH-buffering agent, is provided.

  • Publication number: 20110006009
    Abstract: Provided are an anti-microbial matrix and filtration systems containing the same. The matrix comprises a surface-modified inorganic component and a polymeric binder comprising particles having an irregular, convoluted surface. The surface-modified inorganic component comprises a reaction product of an anti-microbial component and an inorganic component. The anti-microbial component comprises a quaternary ammonium salt containing an epoxide group. A covalent bond is, for example, between the quaternary ammonium cation and a hydroxyl group of the inorganic component. The quaternary ammonium salt can be poly(methyldiallylamine epichlorohydrin). Further, the quaternary ammonium salt can have the formula according to I: (Formula I), wherein n is in the range of 5 to 24. The inorganic component can be diatomaceous earth. The polymeric binder can comprise ultra high molecular weight polyethylene (UHMW PE). Methods of making and using the same are also provided.

  • Publication number: 20100278695
    Abstract: The invention provides improved separation media for use in chromatography and electrophoresis, or for the selective absorption of certain components of a sample mixture, especially in a preliminary stage of an analysis. Improved media according to the invention comprises first particles capable or retaining one or more of the components of a sample mixture and second particles selected to have a higher thermal conductivity than the first particles, so that the thermal conductivity of the media is higher than that of media comprising the first particles alone. The media may be incorporated in packed or capillary columns for chromatography (especially nanoflow HPLC) or for capillary electrophoresis, or may be coated on a substrate. Particular embodiments of the media may comprise mixtures of first particles comprising siliceous polymers, second particles of gold, diamond or graphite. Chromatographic columns and apparatus incorporating them are also disclosed.
