13)Industrial waste Water Treatment

 13)  Discuss Industrial Wastewater Treatment  Introduction Industrial wastewater contains pollutants such as suspended solids, organic matter, oils, toxic chemicals, acids, alkalis and heavy metals. Treatment is necessary before reuse or discharge. Major Stages 1. Preliminary Treatment Screening Removes large floating materials such as: Plastics Wood Rags Large solid particles Grit Removal Removes sand, grit and other heavy inorganic particles. 2. Primary Treatment Sedimentation Wastewater is kept in settling tanks so that suspended solids settle as sludge. Oil and Grease Removal Oil separators or skimming systems remove floating oils and grease. 3. Secondary Treatment This stage mainly removes biodegradable organic matter using microorganisms. Activated Sludge Process Wastewater is aerated in the presence of microorganisms. Organic matter is biologically oxidized. Organic matter + O₂ → CO₂ + H₂O + New biomass Trickling Filters Wastewater passes over a microbial film g...

  Table of Contents Biodiversity Types of Biodiversity Importance of Biodiversity Biodiversity in India Biodiversity Definition “Biodiversity is the variation among living organisms from different sources including terrestrial, marine and desert ecosystems, and the ecological complexes of which they are a part.” What is Biodiversity? Biodiversity describes the richness and variety of life on earth. It is the most complex and important feature of our planet. Without biodiversity, life would not sustain. The term biodiversity was coined in 1985. It is important in natural as well as artificial ecosystems. It deals with nature’s variety, the biosphere. It refers to variabilities among plants, animals and microorganism species. Biodiversity includes the number of different organisms and their relative frequencies in an ecosystem. It also reflects the organization of organisms at different levels. Biodiversity holds ecological and economic significance. It provides us with nourishment, ...

methylcyclohexane conformations

Image
  methylcyclohexane conformations: 1) Methylcyclohexane is cyclohexane in which one hydrogen atom is replaced with a methyl group substituent.  2) Methylcyclohexane can adopt two basic chair conformations:  one in which the methyl group is axial, and one in which it is equatorial .  3) The most stable conformation of methylcyclohexane is the  chair conformation in which the methyl group is equatorial. 4) The alternative chair conformation, in which the methyl group is axial, is 7.3 kJ/mol higher in energy.  5) This difference corresponds to a equatorial:axial conformer ratio of 19:1 at  25 °C.
