Visual inspection cannot determine if water is of appropriate quality. These standards usually include minimum and maximum concentrations of contaminants, depending on the intended purpose of water use. The standards for drinking water quality are typically set by governments or by international standards. Purifying water may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, fungi, as well as reducing the concentration of a range of dissolved and particulate matter. The methods used include physical processes such as filtration, sedimentation, and distillation biological processes such as slow sand filters or biologically active carbon chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light. Most water is disinfected for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including fulfilling the requirements of medical, pharmacological, chemical and industrial applications. The goal is to produce water fit for a specific purpose. Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from water.
