Domestic drinking water
Water purification is the process of removing undesirable chemical and biological contaminants from raw water. The goal is to produce water for human consumption (drinking water). In general the
methods used include physical process such as filtration biological processes such as activated carbon filter, reduction of harmful dissolved salts by Reverse Osmosis method and the use of
electromagnetic radiation such as ultraviolet light.
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 minerals that water may have made contacted after falling as rain.
The standards for drinking water quality are typically set by Governments or by international standards. These standards will typically set allowable minimum and maximum concentrations of
contaminants in drinking water
The table below shows the importance of using a R O based system for drinking water.
