Filteration:
- Filteration removes fine floc particles, colour, dissolved minerals, and microorganisms.
- It also removes the suspended solids that do not get removed in sedimentation.
- It is economically effective in controlling guinea warm disease.
The following different types of filter materials are used for the water filtration process:
- Carbon or Activated carbon: Carbon is also known as charcoal. Anthracite is mostly used for the water filtration process.
- Sand (garnet sand): Garnet sand (chemically inert or non-metallic mineral) is an ideal water filter media.
- Ceramic
- Gravel
- Activated aluminum
- Reverse osmosis membrane, etc.
Hence, sand, anthracite, and garnet sand are used as filter material for water treatment but the crushed rock is not used.
