- What is the use of water purifier?
Water purificationÂ also meets the needs of medical, pharmacological, chemical, and industrial applications for clean and potableÂ water. TheÂ purificationÂ procedure reduces the concentration of contaminants such as suspended particles, parasites, bacteria, algae, viruses, and fungi.
- What are the types of water purification?
The methods used include physical processes such asÂ filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination; and the use of electromagnetic radiation such as ultraviolet light.
- What is a filter?
Filtration is the process in which solid particles in a liquid or gaseous fluid are removed by the use of aÂ filterÂ medium that permits the fluid to pass through but retains the solid particles. Other media, such as electricity, light, and sound, also can be filtered.
