2. Water treatment - Wikipedia

   en.wikipedia.org/wiki/Water_treatment

   Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable ...

3. Sedimentation (water treatment) - Wikipedia

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

   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. Clarifier - Wikipedia

   en.wikipedia.org/wiki/Clarifier

   Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. [1] A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and/or thickening. Inside the clarifier, solid contaminants will settle down to the bottom of the tank where ...

5. Dissolved air flotation - Wikipedia

   en.wikipedia.org/wiki/Dissolved_air_flotation

   Dissolved air flotation. Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.

6. Water purification - Wikipedia

   en.wikipedia.org/wiki/Water_purification

   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. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out ...

7. Water tank - Wikipedia

   en.wikipedia.org/wiki/Water_tank

   An elevated water tank, also known as a water tower, will create a pressure at the ground-level outlet of 1 kPa per 10.2 centimetres (4.0 in) or 1 psi per 2.31 feet (0.70 m) of elevation. Thus a tank elevated to 20 metres creates about 200 kPa and a tank elevated to 70 feet creates about 30 psi of discharge pressure, sufficient for most ...
