Water is one of the basic necessities of life, and access to clean drinking water is a fundamental human right. However, due to pollution and other environmental factors, access to clean water is becoming increasingly scarce. To combat this issue, water treatment plants use various methods to purify water.
What is Water Purification?
Water purification is the process of removing unwanted impurities from water to make it safe for consumption. The process involves the removal of contaminants such as bacteria, viruses, dissolved minerals, and other harmful substances from the water.
What are the Goals of Water Purification?
Water purification has several goals, including:
1. Removing Harmful Substances
The primary goal of water purification is to remove harmful substances from water. These substances can include bacteria, viruses, pesticides, and heavy metals. By removing these substances, the water becomes safe for consumption.
2. Improving Taste and Appearance
Another goal of water purification is to improve the taste and appearance of water. Water that is not purified may have a strange taste, odor, or appearance due to the presence of impurities. By purifying the water, it becomes more pleasant to drink.
3. Reducing Health Risks
Purifying water also helps to reduce the risk of waterborne illnesses. Drinking contaminated water can lead to various health problems, including diarrhea, cholera, and typhoid fever. By purifying the water, the risk of these illnesses is significantly reduced.
What are Not the Goals of Water Purification?
While water purification has several goals, there are also some things that are not the goals of water purification. These include:
1. Adding Nutrients
Water purification is not intended to add nutrients to water. Some people believe that adding nutrients to water, such as vitamins or minerals, can make the water healthier. However, water purification is not designed to add nutrients to water.
2. Altering pH Levels
Water purification is also not intended to alter the pH levels of water significantly. pH is a measure of the acidity or alkalinity of water, and altering the pH levels can have adverse effects on the human body. Therefore, water purification methods are designed not to alter the pH levels of water significantly.
3. Removing Natural Minerals
Finally, water purification is not intended to remove natural minerals from water. Some minerals, such as calcium and magnesium, are essential for human health. Therefore, water purification methods are designed not to remove these minerals from water.
Water purification is an essential process that helps to ensure access to clean drinking water. The primary goal of water purification is to remove harmful substances from water and reduce the risk of waterborne illnesses. While water purification has several goals, there are also some things that are not the goals of water purification, including adding nutrients, altering pH levels, and removing natural minerals.
