Patent number: 8187462Abstract: A process is provided for increasing the production of PHA in a mixed culture biomass. In a first stage of the process, organic material associated with a substrate is converted to volatile fatty acids. In the case of a wastewater treatment process, if the wastewater includes sufficient volatile fatty acids (VFAs) to support the process, then it is unnecessary to convert organic material to VFAs.

By providing relatively high organic loading in the form of VFAs in the anaerobic treatment phase of the selection process, glycogen accumulating organisms having a relatively high level of stored glycogen are produced. In a third stage, the PHA accumulation process is practiced where the glycogen rich organisms are fed VFAs under anaerobic or aerobic conditions or combinations thereof.Type: GrantFiled: February 12, 2010Date of Patent: May 29, 2012Assignee: OTV SAInventors: Simon Olof Harald Bengtsson, Alan Gideon Werker, Paulo Alexandre da Costa Lemos, Maria Ascensao Carvalho Fernandes de Miranda Reis

Patent number: 8124401Abstract: The invention relates to a method and a system for producing biofertilizers, from sludge that are stabilized, dried, and rich in fertilizing matters originating from high load effluent treatment method. Such solution may be integrated into an already existing treatment facility for industrial, municipal, or agronomical organic effluents (100), and is based on recovering the thermal energy created during the treatment steps of such system in bioreactors (120), air suppression units (122), biodrying units (500), drying units (600), and other units. Such recovery of energy creates a synergy that allows the increase of efficacy and yield of bioreactors (120) due to a greater stability from the temperature regulation, thus ensuring an important energy saving for the final drying step in producing biofertilizers.Type: GrantFiled: June 2, 2006Date of Patent: February 28, 2012Assignee: Institut de Recherche et de Développment en Agroenvironnement Inc.Inventors: Camil Dutil, Dan Zegan, Jocelyn Douhéret, Rock Chabot

Patent number: 8114659Abstract: This apparatus introduces catalysts and fluids into a media to effect remediation of contaminants, improve soil fertility and permeability, control undesirable pests, or create useful chemicals or food. The apparatus generates and releases enzymes, metabolites, and biologically active organisms. Aerobic metabolism of compounds in a media is facilitated through the transfer of fluids, such as air. The apparatus and methods provide an environment for select organisms, including refugia and nutrient substrate. The biodegradable composition of the apparatus is partially transformed by catalytic treatment. Catalysts or remediation agents are produced in-situ, for specific applications that provide a range of retention, activation, activity, and release profiles. The apparatus is placed in contact with media. Catalytic infusion of media by biological consortia, such as fungi, releases exudates that transform or biodegrade materials.Type: GrantFiled: January 14, 2009Date of Patent: February 14, 2012Inventors: Robert William Rawson, Mia Rose Maltz

Publication number: 20120021499Abstract: A method for removing pollutants in pollutants-contaminated soil is disclosed. The method includes following steps. A biodiversity system with microbial biodiversity characterization is used to induce growth and reproduce of at least one dominant synergistic flora for petroleum degradation. Most of the petroleum in the soil can be degraded when the temperature of the biodiversity system is below 30-50° C. The remained petroleum in the soil is than rapidly washed out from the soil through forming a petroleum-in-water emulsion by biosurfactant synthesized by the microorganisms in the biodiversity system.Type: ApplicationFiled: January 24, 2011Publication date: January 26, 2012Inventor: Chi-Tsan Lin

Publication number: 20110318817Abstract: An air purifier with a tub capable of containing a liquid. Reactor plates are in the tub wherein the reactor plates provide a curvilinear path for air flow with abrupt directional change. A pump is situated to distribute the liquid onto the reactor plates to form a moist surface. An air inlet brings contaminated air into contact with biocatalyst on the moist surface thereby forming purified air. An air outlet discharges said purified air from the air purifier.Type: ApplicationFiled: October 1, 2010Publication date: December 29, 2011Applicant: sgblue, Inc.Inventors: Wesley O. Greene, Brian D. Summers, Roy D. Crowninshield
