Nowadays, the resources such as rivers, lakes, ponds, and wells of supplying drinking water are polluted with several harmful chemicals and contaminate that may affects negatively on health. Especially if we are getting water from public water supply as there is a big possibility that some unhealthy and dangerous components may be combined with water that can be causes of several illness within a human body. So, it is very important to make drinking water safe and clean. There is no need to worry about that, because there is a process to remove these components from our drinking water. This is known as water purification or water filtration process. Water purification process uses water filters to remove all impurities from water and make our drinking water ph level. It is very complicated process, so with this article we will try to know about how water filters work to remove impurities?

How filters remove impurities in water?

Water purification or filtration can be divided into different categories and classification as these processes differ in the kind impurities of water that people want to remove from water. How filters remove impurities from water really depends on the water filtration process and filter equipments.  For example, reverse osmosis, it is a technology in which we can remove impurities from water by using water pressure and choosing what type of minerals should pass the semi-permeable membrane. Some people also know reverse osmosis as ultra purification process, where impurities from water can be removed according to size of contaminants. Second most important process of purifications is distillation that can be used to remove impurities by boiling and killing the impurities such germs and bacteria. There are several companies such as JDHarris Water Distiller Company that are manufacturing best suitable equipment to remove all impurities from the drinking water. If we are talking about water filters, I would like add here that it is all about the units and equipment used in water filtration or water purification. There are different water filters and purification systems available these days that can be used to remove or reduce the impurities from the water, either by physically stopping them or chemically removing them to join the water.

One of the most commonly used is charcoal. It is always considered as ash, but it does not make the water polluted. It has been used as a solid form in water purification or filtration systems or equipments. It has used in the form of granule, so these granules block the large water contaminants and stop them to pass through with the clean and pure water. Nowadays, several new water purifiers invented in modern era that uses chemicals in the process of water purification, these chemicals helpful to remove all impurities included chlorine that is very difficult to remove by using charcoal. These water filters are based on carbon units that attract chlorine's atom to break their connection or bond with water molecules.

Now, I hope you fully understand Why People need water purification or filter equipments?  How filters remove impurities from water really depend on the type of water. Not all types of filters can remove the same types of water contaminants. Each water filters are specially designed to remove specific types of contaminants from the water. So, it is recommended by experts that if you are looking water filters to use at your home to purify your drinking water, you have to know what kind of water supply you have to determine the types and classification of water contaminants that are present in your drinking water.
