Water purification is the process of removing undesirable chemicals, materials, and biological contaminants from raw water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water).
The purification process of water may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, fungi; and a range of dissolved and particulate material derived from the surfaces that water may have made contact with after falling as rain. The basic purification process for drinkable water from the municipal water is through removing the particles, sediment and rust by using a ceramic filter or a sediment filter which can range from 0.1 micron to 5 micron.
Next, charcoal filter using carbon is used to absorb other chemical contaminants mostly chorine and also improve the taste by eliminating odor. Silver carbon is also used to release silver ions which have an anti-bactirial effect.
