Question

Explain water purification system in water works.

Answer 1

Water:

1. Water is used by our bodies to help control body temperature and support other body functions.
2. It is found in all cells, organs, and tissues.
3. Since our bodies lose water through breathing, sweating, and digestion, it's important to drink fluids and eat foods that contain water to rehydrate and replace it.

Water purification system:

1. The process of purifying water, and removing unwanted chemical compounds, organic and inorganic materials, and biological pollutants from water is known as water purification.
2. This process also includes distillation (turning the liquid into a vapor to condense it back into a liquid) and deionization (removal of ions by extracting the dissolved salt).
3. There are several methods used in water purification, including physical processes, such as filtration, settling, or distillation; Biological processes, such as sand filter, and activated carbon; Chemical processes, such as flocculation, chlorination, using ultraviolet light.
4. Waterworks in the city provide drinking water
5. Unwanted chemical compounds, organic and inorganic products, and biological contaminants are removed from the water during this purification process.
6. Step 1: Water is collected in the tank from various sources.
7. Step 2: The collected water is then led to the settling tank, where the solids will settle.
8. Step 3: At this tank, the suspended impurities settle in the form of sediment.
9. Step 4: The filter tank contains gravel, coarse sand, and fine sand. Water from the intake tank enters the filter tank, where the sedimentation process takes place. Simple filtering process
   Sedimentation is a physical treatment where impurities settle. It depends on gravity. This filter tank acts as a simple biological sand water filter. This filters out most of the contaminants present in the water.
10. Step 5: Water from the previous tank enters this chlorinated tank, where microorganisms will be destroyed. This water is germ-free and is now safe to drink. Finally, the treated water is supplied to the cities.

Purpose:

1. The main purpose of water treatment is to provide clean drinking water.
2. Water treatment also meets the needs of medical, pharmacological, chemical, and industrial applications of clean, drinkable water.
3. The cleaning process reduces the concentration of contaminants such as airborne particles, parasites, bacteria, algae, viruses, and fungi. Water purification is done on a large scale (for example, the entire city) to a small scale (for example, individual households).
4. Most communities rely on natural waters as a source of water purification and daily use. In general, these resources can be classified as groundwater or surface water and generally include subterranean aquifers, streams, streams, rivers, and lakes.
5. Due to recent technological advances, the sea and saltwater seas are also being used as alternative water sources for drinking and household use.
