Purification of Water

Purification water removes impurities such as dissolved solids, gases, and harmful microorganisms. It is intended that this process will result in purpose-specific water. While most water purification and disinfection is done to make it safe for human consumption (drinking water), it may also be done for other uses, such as in the medical, pharmaceutical, chemical, and industrial fields. There have been many different approaches used throughout history to clean water. Filtration, sedimentation, and distillation are examples of physical processes; biological processes like slow sand filters or biologically active carbon; chemical processes like flocculation and chlorination; and electromagnetic radiation like ultraviolet light are examples of chemical processes.

In addition to reducing the concentration of various dissolved and particulate materials, water purification may lower the concentration of suspended particles, including parasites, bacteria, algae, viruses, and fungi.

Governments or international organizations usually determine what constitutes acceptable quality for drinking water. Depending on the end use, these guidelines may set the maximum and lowest levels of pollutants that may be present in the water.

You can't tell whether water is safe to drink just by looking at it. Water from an unknown source may include various pollutants, and simple processes like boiling or using a home-activated carbon filter are not enough to remove them all. Although natural spring water was widely regarded as harmless in the 19th century, modern standards require that it be tested to see whether any treatment is necessary. The only way to determine the best purification technique is to conduct a costly chemical and microbiological investigation.
