Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use.
Water purification - Wikipedia. Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water that is fit for specific purposes.
Water treatment is used to optimize most water-based industrial processes, such as heating, cooling, processing, cleaning, and rinsing so that operating costs and risks are reduced. Poor water treatment lets water interact with the surfaces of pipes and vessels which contain it.
Wastewater treatment, the removal of impurities from wastewater before it reaches aquifers or natural bodies of water. Wastewater treatment is a major element of water pollution control. Learn more about the types of wastewater treatment systems, the technologies used, and the history of treating wastewater.
The history of water treatment is a tale of human ingenuity and necessity, driven by the need to provide safe and clean drinking water to populations. Ever since ancient times, people practiced water treatment methods. They used methods such as boiling, sieving, and letting water settle to remove sediments and impurities.
Water treatment is treating water to make it suitable to be used. Providing drinking water is one of the main uses of water treatment. Many factories also need very clean water to make steam or to make high quality products.
Water treatment refers to the process of improving the quality of water with the purpose of serving an end-use. The most common end-uses include drinking water, industrial water supply, water recreation, and for replenishing environmental sources, such as rivers and lakes.
Water and Wastewater Treatment Overview. Wastewater treatment refers to the physical, chemical, and biological processes used to remove pollutants from wastewater before discharging it into a waterbody.
Key facts. In 2021, over 2 billion people live in water-stressed countries, which is expected to be exacerbated in some regions as result of climate change and population growth (1). In 2022, globally, at least 1.7 billion people use a drinking water source contaminated with faeces.
Providing access to safe water is one of the most effective instruments in promoting health and reducing poverty. As the international authority on public health and water quality, WHO leads global efforts to prevent transmission of waterborne disease.
