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).
