  • Patent number: 10017675
    Abstract: Method for separating a polishing material, which is capable of separating and recovering cerium oxide from a used polishing material that is mainly composed of cerium oxide and a regenerated polishing material which can be obtained by the separation method. This method for separating a polishing material is characterized in that a divalent alkaline earth metal salt is added into the slurry of the used polishing material, while controlling the temperature of the slurry within the range of 10-70 DEG C., thereby causing the polishing material to aggregate under such conditions that the mother liquor has a pH of less than 10.0 as the pH is converted to one at 25 DEG C. so that the polishing material is separated from the mother liquor.

  • Patent number: 9901884
    Abstract: A dispensing system includes a dispenser, a logic device, a nozzle, a diluent source, and a solid product. The logic device controls spray on and spray off cycles to pulse diluent supplied to the nozzle. The diluent contacts the solid product to dissolve a portion of the solid product and create a use solution. Pulsing the spray of diluent controls the concentration of the dispensed product in the use solution by limiting the amount of excess dilutant added to the dispensed product. The product is more consistently dispensed and the concentration of the dispensed product in the use solution is more consistent. Additionally, the concentration of the dispensed product in the use solution can be controlled by changing at least one of a volume of diluent dispensed through the nozzle, a pressure of diluent, a pulsed diluent spray frequency, and a pulsed diluent spray duration.

  • Publication number: 20140342041
    Abstract: A combination micro-filtration halogen apparatus safely delivers drinking water by metering doses of concentrated aqueous iodine into a filtered water supply contained within a chamber. Untreated water is poured into the water filter column that allows for gravity to force the water through filters and the filtered or purified water depending on the filters is stored within a lower chamber of the column for disinfection. An aqueous iodine roller metering system controls the amount of iodine dispensed from an aqueous iodine container to the filter column. Turning the roller mechanism accurately meters a selected dose of concentrated aqueous iodine from the iodine container into the lower chamber of the water column. The active residual iodine disinfectant kills microbes in the filtered or purified water making it safe to consume and prevents recontamination. The iodinated drinking water also provides for essential daily human micronutrient requirements.

  • Patent number: 8889002
    Abstract: The invention relates to a device for cleaning fluid media containing particulate matter, particularly from livestock husbandry, by means of ozonization in a closed ozonization container (11) and subsequent separation of the particulate matter portions. A vertically extending hollow cylindrical fixture (17) is disposed in the closed ozonization container (11). The fixture (17) is operatively connected to a rotating agitator shaft (16), wherein agitation means (18, 19) are associated with the agitator shaft (16), and the fixture (17) is equipped with supply lines (22, 23) by means of which ozone can be fed.

  • Patent number: 8871089
    Abstract: The wastewater treatment system includes a hollow, elongate, horizontally disposed, cylindrical body made from plastic is adapted for water storage and treatment. The cylindrical body includes reinforcement ribs formed by a helically wound steel band embedded in the plastic and extending between opposite open ends of the elongate cylindrical body. A voltage source selectively energizes the steel band. A pair of bulkhead members respectively extends across and covers opposite ends of the cylindrical body. A fluid-tight wall is mounted in the cylindrical body, the first bulkhead member, the fluid-tight wall and the cylindrical body forming a fluid-tight tank defining a liquid storage chamber. The second bulkhead member and the fluid-tight wall define a dry liquid treatment equipment chamber. An inlet pipe extends into the tank for admitting the pretreatment liquid into the tank. An outlet pipe extends from the tank and discharges the treated liquid from the tank.

  • Publication number: 20140305856
    Abstract: Utilizing mobile walls, a transportable (or stationary) low cost, low carbon footprint process and apparatus with a granular filter media dry cell (for filter or bed) for dewatering particulate solids from liquid. The mobile wall structures can be made of a rigid structure constructed of new or preferred salvaged materials, assembled, with watertight joints, used, disassembled and stored for redeployment. The walls are set in a keyway utilizing whatever soil composition is available. The walls can be used in the previous Deskins filters as old wall replacement or new wall construction. The invention utilizes a generator that is not dependent upon site or local electricity thus can be operated in any location. All parts can be engineered, fabricated according to the design of the Quick-Dry Filter Dewatering Mobile Process and Apparatus, packed in shipping containers and be readily available for any immediate need.

  • Publication number: 20140305876
    Abstract: A blood storage container suitable for quick and efficient production of a large amount of serum while ensuring high safety, and a method of separating blood and a regenerative medical process using the same are provided. A blood component separation storage apparatus is provided for separating a plurality of blood components of blood so as to be stored therein. The blood component separation storage apparatus includes a blood reservoir for holding the blood and a component storage part connected to the blood reservoir aseptically and in an air-tight manner. The blood reservoir contains an anticoagulant which suppresses coagulation of the blood. The blood reservoir has a serum producing function to remove coagulation factors from the blood to an extent enabling use in practical applications as a serum, and the component storage part stores each blood component generated by separation of the blood in the blood reservoir.

  • Publication number: 20140299546
    Abstract: In a nanofiltration system for removing sulfate impurity from an aqueous brine stream and for recovering the brine, introducing a dilution stream upstream of the feed stream inlet of a nanofiltration module in the system dilutes the feed stream. This increases the amount of brine salt and water obtained in the permeate stream without substantially diluting the concentration of sulfate in the pass stream and hence results in enhanced recovery of brine while efficiently removing sulfate impurity. The system and process is especially suitable for recovering brine and removing sulfate impurity from a brine stream in a brine electrolysis plant. In a conventional system, the heat exchanger typically used to cool the feed stream can be omitted if the dilution stream is provided at a temperature suitably lower than that of the feed stream.
