Water treatment is the process of removing unwanted materials, suspended solids and from water with the aim
of producing water fit for a specific purpose.
Most water is purified for human consumption (drinking water), but can also be designed to purify water for a
variety of other purposes, including meeting medical, pharmaceutical, chemical and industrial applications.
In general, the methods used in these processes are physical such as filtration, deposition, distillation,
biological processes such as slow sand filters or biologically active carbon, and chemical processes such as
chlorine, sintering and the use of electromagnetic radiation such as ultrasound Violet.
Finally, the reverse osmosis process is modern in comparison to other processes, which were commercially
introduced during the ١٩٧٠s. The reverse osmosis process is defined as separating water from a saline
dissolved through a membrane, and no heating or change of shape is required.
