Biological Treatment of Effluent and Waste Water

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 Uranium

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...

Microbial Wastewater Treatment

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.

Factors Affecting Solubility

Factors Affecting Solubility

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:

Bioremediation

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.

Coagulation

Coagulation

Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

Background:

Boron contamination in industrial wastewater poses environmental risks.
Effective boron removal is crucial for chemical landfill effluent management.
Activated alumina and modified activated carbon are potential adsorbents.

Purpose of the Study:

To investigate boron adsorption on activated alumina and activated carbon.
To evaluate the efficacy of calcium chloride, tartaric acid, and mannitol as impregnants.
To determine the optimal adsorbent for boron removal from specific industrial wastewater.

Main Methods:

Static (batch) adsorption experiments to determine isotherms and adsorbent efficiency.
Dynamic (column) experiments to assess adsorptive capacities.
Analysis of wastewater from the Tarnowskie Gory chemical landfill (25-70 mg/L boron).

Main Results:

Impregnation significantly enhanced activated carbon's boron adsorption capacity.
Granulated activated carbon WG-12 impregnated with mannitol showed superior performance.
Adsorption isotherms and dynamic capacities were determined for various modified adsorbents.

Conclusions:

Modified activated carbon, particularly WG-12 with mannitol, is highly effective for boron removal.
The study identified a promising adsorbent for treating boron-laden wastewater from chemical landfills.
Adsorbent impregnation is a viable strategy to improve boron remediation efficiency.
