How to remove impurities from water
Sedimentation• Can remove LARGE solid particles• LARGE particles will settle in water•Forming a layer of sediment at
the bottom
How to remove impurities from water
Filtration (by filter column)• Can remove FINE solid particles• FINE particles will be trapped
•Liquid collected under the column is filtrate
How does the filtrate look?
