Water is one of the most essential elements found on the planet. Water is significant to all living things. It is very important because plants need it to grow and reproduce. Similarly, animals and humans need water to keep them hydrated and in order to maintain a healthy body.
Although, we have an abundant supply of water, not all of it is potable or fit for human consumption. For example, water found on the ocean cannot be drink by people because it contains a lot of salt and minerals that are too much for the body and can be harmful to man.
However, men have always a way of changing his environment for his own benefit. Men need water that is more potable so, they invented water filters. This equipment is a great invention because it can filter harmful chemicals and contaminants from the water. When contaminated water passes through water filters, it becomes clean and can be used for drinking.
Water purification can therefore, be defined as the process of removing chemicals, bacteria, contaminants, hazardous solid waste, and harmful gases from the water. Although most filters are used to produce potable water, it also has other applications.
An example of industry that needs purified water is the hospitals. Hospitals need purified water because they will use it in performing medical operations. Surgeries are very delicate so it is important to avoid the spread of germs and this can be done with the aid of purified water.
Nowadays, you can find a lot of water purifiers in the market. Countries such as USA, Europe and Australia have also made their own filters, so it can be more accessible to their people. People are drinking purified water, which can be bought from several water purifying companies. Water coming from the faucet may not be potable enough for the people’s health and safety. However, filtered water can be available at home when you buy filtration equipment to be attached to your faucet. This contains charcoal and filtration materials to purify the water thus, making your tap water safe to drink.
Before the water purifier was invented, the most common way of cleaning water is through boiling. Boiling is the process of putting the water in a stove so that it would reach a certain high temperature. Once water reaches 100 degree Celsius, it boils thereby killing bacteria and other microorganism found on the water. Although boiling can remove certain bacteria and harmful chemicals from the water, it cannot be considered safe for drinking. It is because of some chemicals cannot be removed even if you boil the water for a longer period of time.
The cleanliness of water cannot be seen just by looking at it. It is therefore very important to use it with water filters, so you can be sure that it is safe. Water filters should also pass certain government rules and standards, so you would know if it is functional and working as advertised.
