What Does
Water Cleaning Mean?
Water cleaning is the process of eliminating all undesirable elements from water, including:
- Suspended solids
- Biological contaminants
- Gases
- Chemicals
The goal of this technique is to make the water suitable for its intended purpose.
Corrosion occurs in water and in systems that make use of it. Therefore, water cleaning techniques should be observed by industries to make water safe and fit for its function.
Water cleaning is also known as water purification.
Corrosionpedia Explains Water Cleaning
In the process of water cleaning, water undergoes disinfection, usually to make it appropriate for human consumption. However, water cleaning may also be utilized for purposes like meeting the conditions of pharmacological, medical, industrial as well as chemical applications.
Techniques used in water cleaning include processes such as:
- Sedimentation
- Filtration
- Distillation
- Chlorination
- Flocculation
- Use of ultraviolet light
Water cleaning can significantly reduce the concentration of:
- Parasites
- Fungi
- Bacteria
- Other microorganisms
- Suspended particles
This process is also capable of dissolving particulate material from various surfaces which water has come in contact with.
Water cleaning begins when coagulants such as alum or lime are added to water, causing the particulates within to clump. Then, the particulates form bigger clumps referred to as "flocs." After this, the water stands for about 24 hours, letting the clumps settle on the bottom.
The next steps are filtration and disinfection with chlorine, followed by aeration, which helps eliminate corrosive elements such as radon. Methods of water cleaning may differ according to industry and the water's intended purpose.
