    Abstract: A filter media component containing activated carbon, which undesirably filters chlorine from water in an aquatic reservoir in which a minimum level of chlorine is desired to be maintained, is inserted into a fluid pumping path for water from the reservoir to reduce levels of cyanuric acid without purging the reservoir. Once levels of cyanuric acid drop below a target reduced concentration, chlorine and other required chemicals may be added to the water to restore proper water balance and increase the chlorine concentration to at least the minimum level of chlorine desired to be maintained. The process, which can be completed in a short period of time with sufficient quantities of activated carbon, need only be performed seasonally of periodically and avoids waste and potential damage associated with purging and replacing the water within the aquatic reservoir to reduce cyanuric acid levels.

The nanostructure material supporting an arsenic ion adsorption compound such as ammonium molybdate can selectively adsorb and remove trace of arsenic ion in the solution by a room temperature treatment without a water conditioning such as pH control. In our removal system of arsenic, extra posttreatments are not needed because special pretreatments are not carried out, and special heating equipments are not used. Accordingly, our removal system of arsenic can be constructed at low cost. Furthermore, it can supply an arsenic-free solution by be constructed at multi stages.

    Abstract: The steel-reinforced HDPE rain harvesting system collects, stores, and pumps harvested rain water for a variety of non-portable uses. The rain harvesting system includes either a horizontally disposed or vertically disposed steel-reinforced plastic cylindrical wetwell connected to an inlet pipe. The inlet pipe discharges rain water into a rain filter made from a pervious concrete manhole lined with a replaceable 20-micron filter cloth. The rain filter allows rain water into the storage section of the wetwell. A high water alarm is disposed in the rain filter and alerts maintenance personnel to clean the filter when needed. A submersible pump is housed in an HDPE pump sleeve outside the wetwell and conveys effluent from a forcemain at the wetwell's bottom portion to a target area. A level monitoring system disposed inside the wetwell selectively activates the pumping system. Maintenance hatches atop the unit are included.

  • Patent number: 8544657
    Abstract: A filter system for removing contaminants from oil based industrial liquids and the like includes a support tube with a permeable sidewall through which the industrial liquid flows in an inside out direction. A multilayer coalescence media surrounds the support tube, and includes at least one layer of a non-woven fibrous material that is partially wettable by the dispersed water in the industrial liquid, and commences coalescence of the same to form small primary water droplets, and at least one sheet of a precisely woven monofilament fabric stacked on the downstream side of the non-woven material. The woven fabric is substantially wettable by the dispersed water, and has a fixed open mesh with uniformly sized and spaced apart pore openings which continue to coalesce the primary water droplets into large water drops which fall from the filter for collection along the bottom of the apparatus.

  • Patent number: 8512552
    Abstract: A mat for cleaning a liquid spill on a surface has a flexible, liquid-permeable outer shell having a top side, a bottom side, and a peripheral edge. The top and bottom sides are mutually fastened at a fastening area so that an interior space is segregated into a plurality of compartments, each compartment retaining an absorbent material therein. The absorbent material is preferably a powdered polyurethane foam material. In one embodiment, the absorbent material within each compartment is contained within a rectangular substantially flat inner section having a top surface, a bottom surface and a peripheral edge, such that the mat is foldable between such inner sections but not easily folded across each inner section.

  • Patent number: 8506819
    Abstract: A system and method of filtering metalworking fluid is disclosed. A particle filter is provided in fluid communication with a sump of machining equipment to filter particles from a metalworking fluid. The metalworking fluid is filtered using the particle filter to remove metal filings and debris from the metalworking fluid. A tramp oil filter is provided in fluid communication with the particle filter to remove tramp oil, wherein the tramp oil filter includes hydrophobic material to absorb oil. The oil-free metalworking fluid may then be re-circulated back to the machining equipment.

  • Publication number: 20130199991
    Abstract: A filtering element for the filtration of a fluid medium comprises a rigid porous support of cylindrical shape having a longitudinal central axis (A) and a plurality of channels for the circulation of the fluid medium to be filtered and collection of filtrate on the periphery of the support. The channels are arranged in the support parallel to its central axis central (A) and define at least three filtering zones which are distributed concentrically and separated from each other by a continuous porous zone. The mean thickness of the porous zone (Z1) closest to the central axis (A) is smaller than the mean thickness of the porous zone (Zn?1) the closest to the periphery of the support (1) and, in the direction moving away from the central axis (A) of the support towards its periphery, the mean thickness of a porous zone is either identical to the next or smaller.
