  • 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.

  • 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.

  • Patent number: 8834724
    Abstract: In reviewing the oil industry for the past 30 years there has been a need for a low maintenance, low cost, space saving Induced Gas Flotation Cell. With this said, a method has been invented to do this by making several changes in the present design philosophy of induced Gas flotation. First by providing a cylindrical vessel we have made a stronger unit with better structural integrity, and minimizing the opportunity for accelerated corrosion, secondly by changing the vital operations of the unit, specifically the recirculation rate of the system, lowering the overall discharge flow and increasing the discharge pressure we have been able to increase retention time and increase bubble dispersion, part and parcel with this change is the addition of multiple Eductors in each cell providing greater gasification per cell. The combination of these changes provides a greater overall efficiency thus the overboard water quality is improved using a smaller vessel to accomplish the objective.

    Abstract: In order to prevent oxidation degradation of a semipermeable membrane and biofouling growth and avoid an increase in cost due to chemicals and the like, the present invention provides a fresh water production method including membrane-filtering raw water with a microfiltration/ultrafiltration membrane module, followed by performing membrane filtration with a semipermeable membrane unit, in which the membrane filtration in the microfiltration/ultrafiltration membrane module is temporarily interrupted, chlorine agent-containing water is fed from a secondary side of the microfiltration/ultrafiltration membrane module to perform back-pressure washing of the microfiltration/ultrafiltration membrane module, thereafter, an ammoniacal compound and/or an amino group-containing compound are added to a primary side of the microfiltration/ultrafiltration membrane module, and the membrane filtration in the microfiltration/ultrafiltration membrane module is resumed.

  • Patent number: 8480886
    Abstract: A multistage immersion type membrane separator includes a liquid air separator, the liquid air separator including an outlet tube, an inlet tube, and a skirt. The outlet tube is cylindrical and has a outlet tube diameter, and the inlet pipe has an inlet pipe diameter of less than the outlet tube diameter. The inlet pipe is attached to and in communication with the outlet tube so that a mixed flow of air and liquid passing through the inlet tube is introduced into the outlet tube and flows circumferentially around the inside of the outlet tube. The inlet pipe is attached to the cylindrical outlet tube so that the inlet pipe is perpendicular to the outlet tube. The outlet tube has two ends, one end being closed and the other end being open. The skirt is attached to the outlet tube and is concentric with the outlet tube. The skirt is attached to the closed end of the outlet tube, and extends to just past the point of attachment of the inlet tube to the outlet tube.

  • Publication number: 20130168326
    Abstract: The invention concerns a method for separating solid and liquor components of a process slurry comprising solid material entrained in a liquor, said method comprising: (a) a pre-treatment step of adding a flocculent to the process slurry and mixing the flocculent and the slurry by selecting a higher extent of mixing in an early stage of said step than in a later stage of said step, and (b) a solid/liquor separation step of allowing separation of solid material, including aggregates of solid material, and liquor of said process slurry to produce process outputs of a clarified liquor and solid material with some entrained liquor. The invention also concernes a method and an apparatus for adding a flocculent to a process slurry.

  • Publication number: 20120279928
    Abstract: A high percentage of fluorine in fluorine-containing water is removed and high purity calcium fluoride is recovered when treating the fluorine-containing water by passing the same through calcium carbonate packed towers provided in series in a plurality of stages, preferably two stages. In a method including passing fluorine-containing water through calcium carbonate packed towers provided in series in a plurality of stages to remove the fluorine in the fluorine-containing water and recover calcium fluoride, the calcium carbonate towers are packed with calcium carbonate with a volume mean diameter of 30 to 150 ?m. By the use of calcium carbonate granules with a volume mean diameter of 30 to 150 ?m, an increase in the purity of the recovered calcium fluoride and an increase in the fluorine removal ratio can be realized with a relatively small device.

  • Publication number: 20120273431
    Abstract: The present inventors have discovered a novel composition, method of making the composition, system, process for treating a fluid containing a contaminant. The fluid may be aqueous. The contaminated fluid may be in the form of a suspension. The treatment reduces the concentration of the contaminant. The reduction in concentration of a contaminant may be sufficient so as to effect remediation of the fluid with respect to the contaminant. The treatment may reduce the concentration of a plurality of contaminants. The present composition, system, and process are robust and flexible. The composition includes zero valent iron, an iron oxide mineral, and ferrous iron. The ferrous iron promotes maintenance of the iron oxide mineral. The iron oxide mineral promotes the activity of the zero valent iron. The process and system may involve multiple stages. A stage may be optimized for treatment with respect to a particular contaminant.
