The Water Filtration Process

The human body is composed of 55% to 78% water depending on body weight. It is because of this that water has been closely linked to the existence and continuation of life. However, what our body needs is not just any water. What we need is potable water that is free from organisms and elements that could harm our body.

One of the ways by which we can ensure the purity of the water that we drink is with the use of a water filtration system. Although there are a number of ways by which water can filtered, most of these involve a four-step process.

The common filtration system starts with pre-filtration or screening. During this stage, water from the source is screened for large debris. In some cases, this is followed by water treatment in order to lower the salt content of the water.

Once the large debris has been removed, the water undergoes a sediment filtration process. In this step, the water passes through a sediment filter such as the Pentek ECP5. The Pentek ECP5 features a filter media made from cellulose polyester with a nominal micron rating of 5 microns. This means that it can trap 85% of particles that are 5 microns or larger in size. A sediment filter can either be a surface filter or a depth filter. The former is a pleated, thin filter that can trap contaminants on their surface, while the latter features a thick wall cartridge that can trap large-sized particles on its surface and smaller particles under the surface.

After the water has passed through a sediment filter such as the Pentek p5, it then undergoes carbon filtration. In this stage, the water usually goes through chemical bonding and mechanical straining; the first part involves the use of activated carbon while the latter makes use of a compacted carbon brick. This step effectively reduces the amount of organic and inorganic chemicals, microbiological, chlorine, color, odor, and turbidity. After this, the water undergoes ultraviolet treatment where viruses, bacteria, fungi, algae, and protozoas are destroyed by large amount of UV rays.

There are a number of online as well as brick-and-mortar companies that offer effective filtration systems such as the Pentek ECP5 which you can use to make sure that your drinking water is safe for consumption.
