The wastewater influent and the phototactic heterotrophic microorganism population together form a bioreactor effluent that is transferred to a light clarifier. The bioreactor effluent is concentrated in the light clarifier to form a low-solids effluent and a high-solids effluent. The concentration is performed by inducing the population of phototactic heterotrophic microorganisms to phototactically self concentrate through exposure to a light having at least one of an intensity and a wavelength sufficient to cause the phototactic heterotrophic microorganism population to migrate away from a source of the light. The high-solids effluent is then dewatered to form a concentrated biomass paste.Type: GrantFiled: March 19, 2010Date of Patent: November 13, 2012Assignee: Algal Scientific CorporationInventor: Geoff Horst

Patent number: 8298492Abstract: A beverage dispenser has a simple configuration that prevents invasion of bacteria into a tank or a raw water container. An air intake 13 is provided on the top of a cold tank 4 so that air is taken in as the water level in the tank is lowered, and an air chamber 14 having an air inlet 16 for the outside air is connected to the air intake 13. In the air chamber 14, an ozone generator 15 generating ozone from oxygen in the air from the air inlet 16 is provided so that bacteria included in the air from outside is killed in the air chamber 14 connected to the air intake 13 by the excellent bactericidal effect of ozone. Invasion of bacteria into the tank or the raw water container is thus prevented with this simple configuration.Type: GrantFiled: January 30, 2009Date of Patent: October 30, 2012Assignee: Kabushiki Kaisha Cosmo LifeInventors: Masaru Shiotani, Nana Shiotani

Patent number: 8293097Abstract: A system for controlling the injection of wastewater treatment chemicals into a wastewater treatment stream includes a holding tank for collecting and holding wastewater being treated, a camera positioned for making images of the wastewater in the holding tank, a computer for automatically making the images of the wastewater in the holding tank at scheduled intervals. The computer analyzes the images in order to determine the necessity for injecting wastewater treatment chemicals into the wastewater stream by measuring the size, distribution and number of pixels of differing colors and appearances, such that pixels of differing colors and appearances represent differing metal moieties in the wastewater stream. A pump and injection port injects wastewater treatment chemicals into the wastewater stream responsive to the analysis of the images indicating the necessity of such injection.Type: GrantFiled: March 17, 2009Date of Patent: October 23, 2012Inventor: Gregory Scott Bowers, Jr.
