Water treatment describes those industrial-scale processes used to make water more acceptable for a desired end-use. These can include use for drinking water, industry, medical and many other uses. Such processes may be contrasted with small-scale water sterilization practiced by campers and other people in wilderness areas. The goal of all water treatment process is to remove existingcontaminants in the water, or reduce the concentration of such contaminants so the water becomes fit for its desired end-use. One such use is returning water that has been used back into the natural environment without adverse ecological impact.
The processes involved in treating water for drinking purpose may be solids separation using physical processes such as settling andfiltration, and chemical processes such as disinfection and coagulation.
Biological processes are employed in the treatment of wastewater and these processes may include, for example, aerated lagoons,activated sludge or slow sand filters.
Gases you will frequently measure here, are : Hydrogen Sulphide (H2S), Chlorine (Cl)
For measuring how much H2S and Chlorine particles are in the water itself, instead of air, use the Uniphos Dissolved Ion Detection Tubes.
