  • Patent number: 8187861
    Abstract: For extracting phosphorous from algae-in a body of water, the algae are deposited into a sealable tank (200) that is then evacuated, thereby rupturing the algal cell walls. The ruptured algae are then moved to a second tank (260), mixed with water and bacterial cultures, and allowed to settle until the lipids rise to the top and the oil-less debris settles to the bottom. The second tank also contains sacrificial (295) and rusted electrodes (320). The phosphorous from the algae combines with the rust. The lipids and debris are then removed. Next, an electrical source (315) causes the rust to be removed from the rusted electrodes and settle. In addition, a phosphorous-rich scum floats to the top. These components are placed in storage containers for later use and the water is returned, thereby reducing its phosphorous content.

    Abstract: A power steering fluid filter has a housing that defines an interior chamber, an inlet port communicating with the upstream end of the interior chamber, and an outlet port communicating with the downstream end of the interior chamber. The housing is for spicing inline with a power steering fluid hose via its inlet and outlet ports. A thimble filter is disposed within the housing and an annular magnet is located at the mouth of the thimble filter. A spring biases the thimble filter and magnet toward the inlet port of the housing. In use, power steering fluid passes through the housing and debris is captured by the thimble filter. Ferrous particles entrained in the fluid flow are attracted to and captured by the magnet. When the thimble filter becomes clogged, it is displaced by the pressure of the fluid against the clogged filter so that fluid can flow around and bypass the thimble filter while still being exposed to the magnet for removing ferrous particles.

  • Patent number: 7662290
    Abstract: The present invention removes contaminants from well water without creating the problem of large volumes of waste liquid disposal. It uses double-cone devices as pressure amplifiers which due to their lack of moving parts avoid the risk of additional contamination of the well and provide a prolonged lifetime. For toxic contaminants, a periodic purging of the concentrated contaminants is required. In the case of (sea) salt contamination, there is no waste brine to be continuously handled at all and the system may be run without interruption over an extended period. In this case, the brine is dumped into the well simply by periodically stopping the plant. The brine pours out of the double-cone unit(s) and due to its higher density, sinks down in the well without disturbing the operation of the purification plant.

    Abstract: A process and system for substantially isoelectric separation of an oil sand slurry is disclosed and described. The process can include mining oil sand, crushing the oil sands, forming a slurry of the oil sands, and transporting the oil sands slurry to a sinusoidal pipe. The sinusoidal pipe acts to digest the slurry from which bitumen can be separated using a hydrocyclone. Overflow from the hydrocyclone can be further treated using a revolving oleophilic device from which bitumen is recovered. Various optional further treatments can be used to dewater and/or further treat the bitumen and other process streams. The use of caustic soda, long-term tailing ponds, and froth flotation can be avoided resulting in an effective production of oil using less water than currently conventional processes.
