INTAKE
• Intake of water from major source to water treatment plant
• 2 types of intake; Surface Intake Submerged Intake

MIXING POINT
• Alum (aluminium sulfat) and Lime (CaO) added to the raw water.
• Then the water will be transferred to aeration tank.

SEDIMENTATION TANK
Sedimentation processes are used to clarify turbid and/or colored waters, and are used in conjunction with chemical precipitation to remove dissolved impurities such as iron, manganese , calcium, and magnesium compounds, as well as silica and fluorides.
• The formation of floc occurred here
• The flocs will settle down at the bottom of the tank.
![Page 16: Working of water treatment plant](https://reader036.fdocuments.us/reader036/viewer/2022062503/587d83311a28abcd648b4679/html5/thumbnails/16.jpg)
• ‘Scrapers’ will push the flocs to the hopper at the bottom of the tank.
• Eventually only clean water will remains in the tank.

FLOCCULATION
• The water treatment process following The water treatment process following coagulationcoagulation, which uses gentle stirring to bring , which uses gentle stirring to bring suspended particles together so they will form suspended particles together so they will form larger, more settleable particles called larger, more settleable particles called flocfloc.
• Floc which is big and heavy will evetually settle down in settling tank.

FILTRATION
• Filters are used in water treatment to remove relatively low concentrations of suspended matter when a high clarity is needed.
They are constructed in a variety of materials (concrete, steel, fiberglass, etc.), are either open-gravity or enclosed pressure type, and for downflow or upflow filtering.
![Page 22: Working of water treatment plant](https://reader036.fdocuments.us/reader036/viewer/2022062503/587d83311a28abcd648b4679/html5/thumbnails/22.jpg)
• The filter media is typically silica sand, or a combination of sand and anthracite.
The media is selected and sized for the particular application and performance desired.

CHLORINE MIXING POINT
• Adding chlorine to the water.
• Chlorine will remove all the dangerous bacteria in the water
• The water is now potable
