  • Patent number: 8715498
    Abstract: A polymer-free method and self-draining self-cleaning apparatus for treatment of water with high total dissolved solids including optional pretreatment, precipitation/flocculation, and separation. The pH is raised by addition of caustic soda and/or soda ash. In a vertical clarifier silo, the feed is gently mixed to cause dissolved solids to precipitate and agglomerate to form suspended flocculates. The clarifier includes an internal mixer surrounded by a cylindrical tube diffuser. Rotation of the mixer provides gentle dual circulation patterns within the clarifier that allow for flocculates of a predetermined size to settle from suspension. The clarifier may also include one or more vertical recirculation lines to recirculate some of the heavier flocculates at the bottom of the vessel into the mixer chamber to enhance precipitation via the seeding effect. The suspended flocculates are stripped from the feed water in a centrifugal separator. The clarifier silo may be trailer mounted for rapid deployment.

  • Patent number: 7507331
    Abstract: A dispenser system that takes high pressure fluid such as a high pressure water source and reduces the volume flow of the high pressure water as it flows into a dispenser with the dispenser having a low pressure outlet, which offers negligible fluid resistance in comparison to the inlet fluid resistance to the dispenser, thereby ensuring that if a dispenser cap is accidentally removed from the dispenser while the unit is in operation the water will not spray out into and onto the user. The dispensing system includes a removable cartridge carrier with adjustable openings and a dispenser housing that one can maintain a uniform flow pattern under different flow rates to provide for a predicable control of a dispersion rate from a dispersant located in the system and a method of predictably changing the dispersion rate of a dispersant.

  • Patent number: 7494803
    Abstract: An apparatus for bio-composting domestic waste from residential dwellings, comprised of a tank, a multi-chambered liner and a separator. Domestic waste influent enters one end of a sluice, which has ribs on its surface directing the influent onto the upper section of an inclined sieve. The inclined sieve is angled downward and is permeable. The influent waste flows down the inclined sieve, and free water drops downward through the sieve while separated waste solids slide off the lower edge of the inclined sieve. The multi-chambered liner is set inside the tank under its lid. The multi-chambered liner is partitioned into a first chamber running the length of the liner on one half its wide, which the other half its width is subdivided into a series of smaller sub-chambers running the length of the liner. The chambers are separated by permeable partitions. The walls of the liner are permeable, as well.

  • Patent number: 7368054
    Abstract: A separator to separate oil and debris from an aqueous fluid includes a container with a cover, the top portion of which includes a control panel access door. The separator draws an aqueous fluid with one or a plurality of skimmers that float on the aqueous fluid inside one or a plurality of corresponding reservoirs. When the separator is operating, the surface portion of the aqueous fluid is drawn into each corresponding skimmer hose and transferred to the separator by a pickup hose. The separator separates oil, debris and any sludge that may be in the aqueous fluid to provide a substantially filtered aqueous fluid. The substantially filtered aqueous fluid is then returned to the reservoirs through an exit hose.

  • Patent number: 7285209
    Abstract: The invention discloses an apparatus for filtration of water from hydrocarbons comprised of a fresh-feed inlet, a first dead end filter, that is hydrophobic, a second sweeping-flow filter, that is hydrophobic, a common housing containing both the first and second filters, a system for the recirculation of the retentate, a chamber for water settling, and an outlet for clean fuel permeate. This invention takes advantage of the properties of the functional groups of a surfactant, by using the surfactant to allow a hydrophobic medium to attract water, attach the water molecules to the hydrophobic medium, and then allow for agglomeration of the water molecules, which finally become large enough to detach and be swept away by the sweeping-flow. This invention can thus be used to remove high concentrations of water, up to 5%, in hydrocarbons, while allowing a high flow rate by preventing blockage of the final filter by water.

  • Patent number: 7267769
    Abstract: A water purification system includes an activated carbon filter and a reverse-osmosis (RO) filter. The activated carbon filter is typically formed with a central aperture that receives an upper portion of a central tube. The RO filter, which is positioned downstream from the carbon filter, may be formed around a perforated section of the central tube. The system further includes a head that is structured to receive a sump that contains the carbon and RO filters, as well as the central tube. An inlet formed in the head enables unpurified feed water to flow into the carbon filter. A first channel, which is defined by an annular surface formed in the carbon filter and an outer surface of the central tube, enables water to flow into the RO filter. A channel within the central tube enables water to flow from the RO filter, through the perforated sections of the central tube, and into an outlet formed within the head.
