Microbial Leaching01:27

Microbial Leaching

Microbial leaching, also known as bioleaching, is an environmentally favorable method for extracting metals from low-grade ores using specific microorganisms. This biotechnological approach is particularly valuable for mining operations targeting copper, gold, and uranium, where traditional extraction methods may be economically or environmentally impractical.Copper Leaching and Microbial CatalysisIn copper bioleaching, crushed ore is arranged into heaps and irrigated with a dilute sulfuric...
Bioremediation00:46

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.
Biological Treatment of Effluent and Waste Water01:30

Biological Treatment of Effluent and Waste Water

Biological wastewater treatment relies on the metabolic activity of microorganisms to remove pollutants from sewage. In modern treatment systems, this process is organized into sequential stages that progressively reduce solid material, dissolved organic matter, and microbial contamination. Each stage plays a distinct role in improving water quality and preparing the effluent for safe discharge or reuse.Primary and Secondary TreatmentPrimary treatment is a physical process that removes large...
Microbial Bioremediation of Hydrocarbons01:26

Microbial Bioremediation of Hydrocarbons

Bioremediation is an environmentally sustainable process that employs living organisms—primarily microorganisms—to degrade or neutralize pollutants from contaminated environments. In oil spills and hydrocarbon pollution, bioremediation involves the use of hydrocarbon-degrading bacteria to transform toxic compounds into less harmful substances. This approach leverages natural microbial metabolic processes and is considered both cost-effective and ecologically favorable compared to physical or...
Microbial Wastewater Treatment01:30

Microbial Wastewater Treatment

Microbial communities in aquatic ecosystems play a key role in the natural breakdown of contaminants introduced through domestic and industrial effluents. Acting as biological catalysts, these microbes change and mineralize a wide range of organic and inorganic pollutants under different redox conditions.In oxygen-rich surface waters, aerobic heterotrophs lead organic matter breakdown, using oxygen as the terminal electron acceptor to efficiently oxidize substrates to carbon dioxide and water.
Microbial Bioremediation of Uranium01:25

Microbial Bioremediation of Uranium

Microorganisms play a critical role in the transformation and immobilization of uranium in contaminated environments through four main pathways: bioreduction, biosorption, bioaccumulation, and biomineralization. These mechanisms reduce uranium’s toxicity and prevent its migration through groundwater systems, offering sustainable approaches for in situ bioremediation.Bioreduction of UraniumBioreduction is driven by anaerobic bacteria such as certain strains of Geobacter and Shewanella, which use...

Area of Science:

  • Environmental Science
  • Water Treatment Technologies
  • Bioremediation

Background:

  • Benzene, toluene, and xylenes (BTX) are common water contaminants.
  • Conventional removal methods like air sparging merely transfer pollutants between phases.
  • There is a need for sustainable and effective BTX removal strategies.

Purpose of the Study:

  • To evaluate a combined strategy for BTX removal from contaminated water.
  • To assess the efficiency of granular-activated charcoal (GAC) for BTX adsorption.
  • To investigate the regeneration of GAC using a bioleaching process.

Main Methods:

  • Adsorption of BTX compounds onto granular-activated charcoal (GAC).
  • Regeneration of GAC-laden BTX using a bioleaching process.
  • Development of analytical tools for accurate contaminant quantification in biomass samples.

Main Results:

  • GAC effectively adsorbs BTX, with high retention capacities (xylenes: ~350 mg/g, toluene: ~250 mg/g, benzene: ~150 mg/g).
  • Adsorbed BTX remains available for in situ biodegradation.
  • The bioleaching process shows potential for efficient GAC regeneration.

Conclusions:

  • The integrated GAC adsorption and bioleaching strategy is a promising method for BTX removal from water.
  • This approach minimizes environmental damage by avoiding pollutant transfer to the gas phase.
  • The study highlights the importance of analytical tools for process monitoring and material balance calculations.
