    摘要: A biologically active support is provided for removal of pollutants such as aliphatics, aromatics, heteroaromatics and halogenated derivatives from waste streams. The support contains a particulate adsorbent such as activated carbon bound by a polymer binder to a substrate such as a polymeric foam, and a bound pollutant-degrading microorganism. The adsorbent adsorbs a target pollutant, and the microorganism degrades the pollutant. Preferably, the microorganism is aerobic and the binder has a Tg of lower than or equal to about 25° C. The adsorbent adsorbs excess pollutant when the pollutant concentration increases and releases the pollutant when the concentration decreases. This maintains the pollutant concentration at a level which does not inhibit the microorganism. The biologically active support can be used in conventional biological waste treatment systems such as continuous stirred reactors, fixed-bed reactors and fluidized bed reactors.

    摘要: Methods for producing hydrocarbon oils from algal biomass are provided. The algal biomass is hydrogenolysed under reaction conditions sufficient to produce a partially deoxygenated lipid-based oil. The algal biomass may be whole algal biomass, residual algal biomass, or both. The algal biomass is hydrogenolysed by liquefying the algal biomass in the presence of a hydrogenolytic catalyst in a hydrogen atmosphere at an elevated temperature and pressure to produce an organic phase containing the partially deoxygenated lipid-based oil, an aqueous phase, and a solid phase. The aqueous and solid phases may be removed from the partially deoxygenated lipid-based oil. The partially deoxygenated lipid-based oil is then substantially deoxygenated using a hydroprocessing catalyst to produce the hydrocarbon oil.

    摘要: A biological system for removing selenium from waste water comprises a first immobilized cell bioreactor (ICB) and a selenide removal module. The first ICB comprises a chamber having a substrate housed therein and situated to contact the waste water flowing therethrough during use. Anaerobic microorganisms are supported on the substrate, and comprise selenium respiring bacteria capable of reducing selenates and selenites to insoluble elemental selenium and/or sulfate reducing bacteria capable of reducing selenates and selenites to insoluble elemental selenium or to soluble selenides. The selenide removal module includes metallic or oxidized iron compounds capable of chemically reacting with selenide or sulfide compounds in the waste water to form iron selenide or iron sulfide precipitates.

    摘要: The present invention provides an improved biological sludge dewatering process. The process comprises the steps of: (a) heating biological sludge to a temperature of about 90.degree. to about 150.degree. C. which corresponds to a pressure of about 0 to about 55 psig and retaining the biological sludge at that temperature for less than about 15 minutes; (b) centrifuging the heated biological sludge to isolate the solids of the heated biological sludge from the liquid of the heated biological sludge; (c) chemically conditioning the isolated solids; and (d) dewatering the conditioned solids to produce a high solids biological sludge. The present process is used for dewatering any biological sludge to produce a high solids cake. The resulting high solids cake may be used as landfill, incinerated, or used as fertilizer by spreading on land and plowing said fertilizer into the soil.
