  2. Water treatment - Wikipedia

    en.wikipedia.org/wiki/Water_treatment

    Physical techniques of water/waste water treatment rely on physical phenomena to complete the removal process, rather than biological or chemical changes. [9] Most common physical techniques are: Sedimentation is one of the most important main wastewater treatment procedures. Gravity settling is a method of separating particles from a fluid.

  3. Sedimentation (water treatment) - Wikipedia

    en.wikipedia.org/.../Sedimentation_(water_treatment)

    The physical process of sedimentation (the act of depositing sediment) has applications in water treatment, whereby gravity acts to remove suspended solids from water. [1] Solid particles entrained by the turbulence of moving water may be removed naturally by sedimentation in the still water of lakes and oceans.

  4. Camphor - Wikipedia

    en.wikipedia.org/wiki/Camphor

    Camphor (/ ˈ k æ m f ər /) is a waxy, colorless solid with a strong aroma. [5] It is classified as a terpenoid and a cyclic ketone.It is found in the wood of the camphor laurel (Cinnamomum camphora), a large evergreen tree found in East Asia; and in the kapur tree (Dryobalanops sp.), a tall timber tree from South East Asia.

  5. Phase diagram - Wikipedia

    en.wikipedia.org/wiki/Phase_diagram

    The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question. A phase diagram in physical chemistry , engineering , mineralogy , and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct ...

  6. Coagulation (water treatment) - Wikipedia

    en.wikipedia.org/wiki/Coagulation_(water_treatment)

    In water treatment, coagulation and flocculation involve the addition of compounds that promote the clumping of fine floc into larger floc so that they can be more easily separated from the water. Coagulation is a chemical process that involves neutralization of charge whereas flocculation is a physical process and does not involve ...

  7. Water purification - Wikipedia

    en.wikipedia.org/wiki/Water_purification

    Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water that is fit for specific purposes. The goal is to produce water that is fit for specific purposes.

  8. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Although hydrogen bonding is a relatively weak attraction compared to the covalent bonds within the water molecule itself, it is responsible for several of the water's physical properties. These properties include its relatively high melting and boiling point temperatures: more energy is required to break the hydrogen bonds between water molecules.

  9. Sewage treatment - Wikipedia

    en.wikipedia.org/wiki/Sewage_treatment

    Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.
