The water coming from its natural sources, whether it is groundwater such as artesian wells or from water bodies such as streams and lakes, is filtered in several ways in order to get rid of various pollutants that threaten human health and living organisms, and there are a number of methods that we will mention
The live filter is one of the oldest methods used in water filtration and purification, which consists of a tank in which successive layers are placed starting with a bed of reeds to remove plankton from bacteria, nutrients and organic materials, then the water moves to the next layer consisting of gravel, sand, and coal, which leads Finally, to the production of purified water that is collected in other tanks.
are filtering water based on two principles, physical and chemical. The physical filter is based on purifying water from pollutants such as small particles that can be observed, and the chemical filter, through which active chemical compounds are added that purify the water passing through it. Example of the various great modern ways:
This filter is the most common, as the most important components of this mechanism in water filtration are the use of filters consisting of sand and activated carbon, which plays a major role in attracting chemicals to it such as: chlorine and pesticides.
The principle of reverse osmosis is used in water purification, where water filters based on this mechanism consist of tanks in which polluted water is located, connected to pure water tanks with tubes containing a membrane usually composed of cellulose acetate that separates polluted water and clean water, In addition to an electric pump that pushes the water to be purified through the membrane, the reverse osmosis filter is usually used in desalination plants that produce high purity water, where this system mainly consists of several components:
water filter is a device that filters and purifies water from contaminants, as chemical compounds are eliminated, in addition to biological contaminants from viruses, bacteria, organic and inorganic plankton, and any dissolved salts, which produces pure water suitable for drinking and use in various fields.
