Patent number: 8187861Abstract: 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.Type: GrantFiled: February 26, 2010Date of Patent: May 29, 2012Inventor: Allen John Schuh
