  • 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 pretreatment particle-accelerating deposition and separation apparatus and method for purifying turbid raw water, which based on the theories of laminar flow requirement, particle-accelerating vertical deposition and water horizontal movement, separates water molecules from turbidity particles in a laminar flow region (with a Reynolds number lower than 1,000). By accelerating the velocity of high-turbidity raw water and the turbidity particles, the particles settle vertically because of inertia. Thus, the turbidity particles can be removed physically from the raw water and clean water can be collected at different heights of the apparatus while concentrated turbid water can be released to a nearby body of water after appropriate treatments. Thereby, turbid water can be purified for the subsequent coagulation, sedimentation and filtration processes in traditional water treatment plants.

    Abstract: The present processing apparatus blocks off such a portion of a flow of a plating solution (17) that is other than a vicinity of a liquid surface, by using a first partition plate (15) whose lower end is in close contact with a bottom of a plating tank (11) and whose upper end is at a position lower than a liquid surface. Therefore, the plating solution (17) flowing at the bottom of the plating tank (11) flows upwards along the first partition plate (15). At this time, heavy foreign substances do not tend to follow such an upward movement of the plating solution (17), and therefore sink and accumulate in a vicinity of the lower end of the first partition plate (15), so as not to flow into a downstream side of the plate. With this arrangement, the present processing apparatus can remove the heavy foreign substances from the plating solution (17) without relying solely on a filter of a circulation pipe (10).

  • Patent number: 7364661
    Abstract: A mixture of fluids is separated into at least two phases, one of which has a higher density than the other, passing the mixture through a normally horizontal supply pipe, by creating a stratified flow in the supply pipe, by passing the mixture through an inclined pipe, whilse maintaining a stratified flow in the inclined pipe, by extracting fluid with lower density (“lighter phase”) via a first discharge system and fluid with a higher density (“heavier phase”) via a second discharge system, wherein the interface between the lighter phase and the heavier phase is monitored in the inclined pipe by a level controller means that varies the flow of the fluid of higher density to keep the interface between set levels.

  • Patent number: 7083736
    Abstract: A system for extracting free oil from industrial processing fluids contains a solids retention cartridge having a plurality of vertically oriented polymeric elements therein. The cartridge fluidly communicates with a retention chamber, wherein the retention chamber provides a predetermined residence time based on fluid flow as established by inlet and outlet pressure and also as established by valved fluid exit orifices. An aggregation chamber fluidly communicates with the retention chamber and provides an area for aggregation of a low density fluid such as oil for example. The low density fluid is then decanted from a decant chamber. The purified bulk fluid is drained from the retention chamber through an associated return chamber. The average cross-sectional area of the aggregation chamber is less than the average cross-sectional area of the retention chamber thereby enhancing the aggregation of a lower density fluid such as oil, prior to decant.
