Area of Science:
- Environmental Science
- Chemical Engineering
- Water Treatment Technologies
Background:
- Industrial activities generate complex wastewaters.
- Effective treatment is crucial for environmental protection.
- Diverse sectors like agriculture, chemical, dye, petrochemical, and pharmaceutical produce significant wastewater volumes.
Purpose of the Study:
- To review 2019 literature on wastewater treatment methods.
- To identify effective agents for various industrial effluents.
- To provide insights into current wastewater management practices.
Main Methods:
- Literature review of studies published in 2019.
- Focus on wastewater from agricultural, chemical, dye, petrochemical, and pharmaceutical industries.
- Analysis of practitioner-reported treatment techniques.
Main Results:
- Bioflocculant chitosan demonstrated efficacy in sludge dewatering and wastewater treatment.
- Alkaline lignin-based flocculants achieved high color removal from paper mill sludge.

Types of Toxins
3.0K
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Chemical Agents for Microbial Control
641
Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

Toxic Reactions: Overview
1.7K
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Bioremediation
21.9K
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.

Methods of Sterilization II: Chemical Methods
8.7K
In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...
