  • System for bioremediation of effluents

    Executive Summary The remediation process of commercial, municipal, industrial and agricultural wastewaters has employed combinations of sulfuric acid, caustic, petroleum based solvents and synthetic emulsifiers, which are either toxic or generally non-biodegradable. An alternate method using naturally occurring microorganisms has been utilized for many years to facilitate the remediation ...

  • Membrane-integrated hybrid bioremediation of industrial wastewater: a continuous treatment and recycling approach

    A new membrane-integrated hybrid treatment system was investigated to turn highly hazardous coke wastewater reusable. This could protect both air and surface water bodies from toxic contaminants such as ammonia, phenol, cyanide, thiocyanate and other carcinogenic aromatic compounds which are normally released into the environment during discharge of coke wastewater and during quenching of coke ...

  • Bioremediation of Effluent the Pulp and Paper Industry

    The treatment of industrial effluent from the paper manufacturing facilities in British Columbia is a major concern because the effluent is discharged into prime salmon habitat in the marine environment (Cross, 1994). High levels of biological oxygen demand (BOD) in the effluent reduce the dissolved oxygen (DO) available to species in the marine environment. In 1988, the Federal Department of ...


  • An experimental study on bioremediation and photolysis of enrofloxacin

    Recent studies have identified the occurrence of a vast number of pharmaceuticals into the municipal wastewater through excreted urine and feces. Some of these pharmaceutical compounds are degraded in the environment. However, there have been reports on the presence of pharmaceutical active compounds in drinking water. Concerns have been raised over the potential adverse effects of these ...

  • Biological Reduction of Hexavalent Chromium: A Potential Strategy for the Bioremediation of Cr(VI)-Pollutied Wastewater

    ABSTRACTThe potential for biological treatment of Cr (VI)- polluted wastewaters has attracted increased interest, because this alternative is more efficient and less expensive than conventional physicochemical treatments. In this work, a microbial enrichment capable of tolerating and reducing high Cr(VI) was isolated. The kinetic parameters of the Cr(VI) reduction process indicate that the ...

  • Operating conditions for the continuous bioremediation of free cyanide contaminated wastewater using Aspergillus awamori

    Generation of cyanide-containing wastewater is a growing problem worldwide as numerous cyanide complexes are highly unstable and degrade to form free cyanide (F-CN), the most toxic form of cyanide. Agro-waste materials, such as sweet orange (Citrus sinensis) waste from the citrus industry, are rich in readily metabolisable carbohydrates that can supplement microbial activity and thus support ...

  • A Tale of Two Sites - Enhanced Bioremediation of Explosives Impacted Soils

    The problem with OE compounds in soil A variety of organic explosive (OE) compounds have been used for military, geological and industrial applications throughout North America, and in most industrialized nations. During their manufacture, formulation and storage, these compounds have migrated to the soil. Compounds such as 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine ...


  • Bioremediation of heavy metal contaminated aqueous solution by using red algae Porphyra leucosticta

    Bioremediation is an effective process for the removal and recovery of heavy metal ions from aqueous solutions. In this study, red algae Porphyra leucosticta was examined to remove Cd(II) and Pb(II) ions from wastewater through biological enrichment and biological precipitation. The experimental parameters that affect the bioremediation process such as pH, contact time and biomass dosage were ...

  • Treating wastewater as a resource

    A number of UK landfill operators are turning wastewater into a resource by utilising OTT monitoring and control systems to manage the irrigation of Willow crops (for renewable energy generation) with pre-treated effluent. Background Leachate from landfill sites represents a significant potential environmental liability, extending long into the future after a landfill site has ...

  • A wastewater plant bio-augmentation success

    Rosethorne WWTP is located in Jefferson Parish, Louisiana, just west of New Orleans. The plant was constructed in the mid-1990s with a design capacity of 400,000 GPD. Today, the average daily flow through the plant is approximately 250,000 GPD. During Hurricane Katrina, in 2005, the plant suffered considerable damage to its mechanical infrastructure, and even after repairs, its effluent was ...
