Which is the purification of water?
There are several methods used in the water purification process, which include: (1) physical processes, such as filtration, sedimentation, or distillation; (2) biological processes, such as sand filters, active carbon; (3) chemical processes, such as flocculation, chlorination, the use of ultraviolet light.
What are impurities of water?
The types of impurities in water can include dust, dirt, harmful chemicals, biological contaminants, radiological contaminants, and total suspended solids (TSS). Total suspended solids are visible particles that can make water appear cloudy or hazy.
How do we purify water definition?

- Screening. As water enters a water treatment plant, either from lakes, rivers, or the ground, it passes through a screening.
- Coagulation.
- Sedimentation.
- Filtration.
- Disinfection.

Which is the first step in water purification?
Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water.
