    Abstract: The invention relates to a device (2) for drinking water purification, having a water tank (4) for receiving the drinking water (6) to be purified, a pump (8) for transporting the water, and a membrane filter unit (10) which comprises a water inlet (12), a membrane filter (14), a pure water discharge (16), and a rinsing water discharge (18). The water inlet (12) is supplied with water directly or indirectly from the water tank (4) via a feed line (24), and is disposed in the flow direction (19) in front of the membrane filter (14). The pure water discharge (16) is disposed in the flow direction (19) behind the membrane filter (14). To remove deposits, part of the water fed to the membrane filter unit (10) via the water inlet (12) is guided across the membrane filter surface and exits the membrane filter unit (10) via the rinsing water discharge (18). In order to increase user friendliness, a water return line (26) connects the rinsing water discharge (18) to the water tank (4).

  • Patent number: 8152995
    Abstract: Hot water pipes, in areas with hard water, tend to fill with scale until they no longer pass enough water. De-scaling water pipes with acid is dangerous, expensive and damages the pipes. Ion exchange and reverse osmosis water softeners eliminate scale buildup in pipes, but are expensive. Embodiments of this invention provide a means of keeping an amount of the scale precipitate, created when water is heated, inside a housing by passing the hot water through a removal medium where the scale sticks to the surface. The removal medium can be placed inside the water heater or in a separate housing connected to the water heater; both configurations remove the precipitate from hot water; both save hot water pipes from scale accumulation.

    Abstract: A system and method for powering an ultraviolet (UV) water purification system utilizing a dynamo. A dynamo, operably attached to the UV water purification system, generates power from a rotatable crank which is actuated by a user around an axis of the rotatable crank. When the crank is rotated, the dynamo produces an electrical current that activates and powers the UV lamp, which in turn, produces UV light to purify the water. To ensure that the water has been purified appropriately, a microcontroller, employed within the UV water purification system, tracks both the “on” time and the intensity of the UV lamp as the dynamo is cranked. Once the lamp has been “on” at a sufficient intensity and for an appropriate period of time to administer a required dose of UV light, the microcontroller disables the lamp and provides the user with notification that the process has completed.

    Abstract: A solvent filtration and recovery system for filtration and recovery of a solvent-based liquid used in dry cleaning includes filtration tank having filter chamber with motor-driven spin filters which are selectively operated. A valve and conduit arrangement allows the liquid from dry cleaning to enter the filter chamber for filtering and flows out as filtered liquid while the spin filters are not rotating. The arrangement allows initial at least partial draining of the solvent-based liquid in the filter chamber after such filtration procedure. A recovery tank is in communication with the filtration tank through a main drain. A motor drives the spin filters during a recovery procedure, in which centrifugal force caused by the rotating spin filters for a predetermined amount of time removes by-product from the spin filters, which is drained off from the filtration tank. A reservoir stores the solvent-based liquid and receives the liquid from both the recovery tank and the filtration tank.

  • Publication number: 20110017678
    Abstract: The present invention includes capturing water from rain, HVAC condensate and refrigeration blowdown/bleed blowdown that is recycled and reutilized in integrated mechanical processes. Water is monitored for volume, flow rate, and contaminants; and automatically cleaned through filtration and/or chemical and/or biological treatment techniques to meet acceptable health and safety standards for engineered end uses. The process components are integrated into an engineered system that includes: 1) water collection from air conditioning and refrigeration units and rain water; 2) custom design, engineering and implementation of a real time and/or scheduled water monitoring for water volume and water quality; 3) custom design, engineering and implementation of a real time and/or scheduled water treatment system to ensure water quality standards are met with respect to the end use of the recovered water; and 4) utilization of the recovered water by an engineered water distribution system.

  • Publication number: 20110017681
    Abstract: Filtration apparatuses for use in polymer processing systems and methods of using the same are provided. The filtration apparatuses can include a housing with one or more supply channels and discharge channels. The filtration apparatus can also include one or more screen-bearing pistons with filter screen cavities therein for receiving filter screens that filter material flowing from the supply channels through the filter screens and out through the discharge channels. Back flushing channels can be formed by alignment of mating channels in the pistons and the housing. The filtration apparatuses can also include a controller that can communicate with a hydraulic power unit to that can be assisted by a rapid accelerator device to control the filtration apparatus. The filtration apparatuses can include filter screen retention plates.

  • Patent number: 7867388
    Abstract: A contaminated fluid recovery apparatus includes a sludge removal mechanism having a dirty tank, a conveyor, and a magnetic drum which is arranged in the fluid circulating section. The contaminated fluid recovery apparatus is provided with an overflow tank. The overflow tank has a function to keep a fluid surface of the dirty tank in a position higher than the fluid circulating section and the magnetic drum. The magnetic drum is located horizontally between a lower portion and an upper portion of the conveyor. The conveyor scrapes out chips deposited on a bottom portion of the dirty tank toward an exit section. A scraping member, which is in contact with the magnetic drum, drops sludge attracted to the magnetic drum toward the lower portion of the conveyor.

  • Publication number: 20100314302
    Abstract: A dissolved air flotation system and method for purifying fresh water. The system is self-contained within a standard shipping container, with all components disposed in-line within the shipping container. Float is removed from the flotation tank with a skimmer that drives float downstream onto a conveyor belt, and the conveyor belt conveys float away from the flotation tank, in the downstream direction, and deposits the float in a collection tank. Clean water may be drawn from the flotation tank continuously, while float may be removed periodically.

  • Patent number: 7828960
    Abstract: A separator for separating F.O.G. from an effluent that contains F.O.G. includes a tank, an inlet to the tank for receiving effluent that contains F.O.G., and an outlet to allow grey water to leave the tank. The tank has a size to enable stratification of a layer of F.O.G. present in the tank on water in the tank, and first and second thermocouples are positioned at differing levels in the tank. Conductors couple the thermocouples to sensors, and differing voltages in the thermocouples can be sensed to determine if the thermocouples are surrounded by F.O.G. or water.
