Microbial Bioremediation of Uranium01:25

Microbial Bioremediation of Uranium

52
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,...

Microbial Leaching01:27

Microbial Leaching

73
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...

Bioremediation

22.9K
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.

Acid Mine Drainage01:19

Acid Mine Drainage

49
Mining activities that disturb sulfide-rich rocks, particularly those containing pyrite (FeS₂), initiate a cascade of geochemical and microbiological processes with serious environmental implications. When exposed to air and water, pyrite undergoes oxidation, releasing sulfate, ultimately forming sulfuric acid and mobilizing heavy metals into surrounding water systems. This phenomenon, known as acid mine drainage (AMD), results in low pH waters laden with toxic elements that threaten...

Factors Affecting Solubility04:01

Factors Affecting Solubility

39.2K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

Precipitation and Co-precipitation01:17

Precipitation and Co-precipitation

5.6K
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...

Area of Science:

  • Environmental Science
  • Chemical Engineering
  • Materials Science

Background:

  • Rare-earth (RE) wastewater contains toxic pollutants and radioactive species, necessitating effective remediation strategies.
  • Existing treatment methods can be costly, inefficient, or generate significant sludge.
  • There is a need for economic and sustainable solutions for RE wastewater treatment.

Purpose of the Study:

  • To develop a novel, economic, and sequential process for remediating rare-earth wastewater.
  • To evaluate the removal efficiencies of heavy metals, radioactive species, fluoride, arsenic, and COD(Cr).
  • To assess the long-term performance and economic viability of the developed process.

Main Methods:

  • A sequential process involving precipitation using porous air stones with waste oyster shell (PASWOS), adsorption using polyurethane impregnated with coal mine drainage sludge (PUCMDS), and oxidation with ozone (O3).
  • SEM-EDS analysis to understand the role of PAS in the precipitation step.
  • Continuous-mode operation for 100 days to evaluate long-term treatment efficacy.

Main Results:

  • PASWOS achieved >97% removal of most heavy metals.
  • PUCMDS effectively removed residual fluoride (F), arsenic (As), uranium (U), and thorium (Th).
  • The continuous sequential process demonstrated high removal efficiencies (99.9-100% for heavy metals, 95.8-99.9% for F, As, U, Th) for 100 days, meeting EPA limits and reducing sludge generation.

Conclusions:

  • The developed sequential precipitation-adsorption-oxidation process is an economic and effective method for rare-earth wastewater remediation.
  • The process eliminates the need for stirred-tank reactors, pH controllers, and continuous chemical injection, simplifying operations.
  • This innovative approach offers a sustainable solution for treating complex industrial wastewater, meeting stringent environmental standards.
