What Are The 5 Stages of Water Treatment?

Millions of people across the globe lack access to clean and safe drinking water, highlighting the seriousness of the problem of water shortage. A water treatment plant is a facility in which waste and polluted water are treated to make it useful again for other purposes. Different water treatment methods, such as filtration, sedimentation, disinfection, and chlorination, are used by different water treatment facilities to clean contaminated water. Furthermore, some of the usual water purification equipment utilized in such facilities includes screening equipment, oil-water separators, water filters, sludge treatment equipment, ozone generators, and other similar items of equipment.

Water Treatment Plant India processes water in the same way as municipal water treatment plants do once it has been drawn from bigger water sources. In vast quantities, this treated water is subsequently utilized for a variety of commercial and household purposes. Water is thoroughly treated before it is sent via the distribution system to supply the customers.

Has anybody ever considered the process by which water is handled in plants, though? When hard water from the ground is softened and subsequently utilized for commercial purposes, there are a variety of techniques available. It is necessary to analyze water for a variety of pollutants, including dangerous amounts of organic, inorganic, microbiological, and/or radioactive contamination. 

Let's have a look at some of the techniques for treating water nowadays.

1. Filtration

Filtration Whatever is still swimming in the water will be ejected in the filtration system, which is comprised of layers of material such as rock, sand, and charcoal that direct watercourses through. These layers are often extremely thick to provide the highest possible level of filtration. The more layers that are used, as well as the quality of the sand, the greater the filtration. In this procedure, a combination water filter softener system may be shown to be the most effective. In addition to this procedure, a facility for purifying surface water for municipal use may be installed thereafter. Surface water treatment techniques such as screening, aeration, sedimentation, sand filtration, and disinfection are used to remove the colloidal matter, organic components, and suspended pollutants present in the surface water during this process.

2. Screening

When water from lakes, rivers, or the ground enters a water treatment facility, it goes through a screen to be treated. For lakes and rivers, the screen performs an essential role by preventing big natural pollutants like plants and timber, as well as fish, from getting into the water supply. If groundwater is utilized, screening may not be required since the water has gone through layers of the earth, which is a natural screening function, reducing the likelihood of contamination.

3. Aeration 

Following the screening, the water is aerated (provided with air) by passing it through a series of stages that allow it to absorb oxygen from the surrounding air. This method aids in the removal of soluble gases such as carbon dioxide and hydrogen sulfide (both of which are acidic, thus this process makes the water less corrosive) as well as the removal of any gaseous organic compounds that impart an unpleasant taste to the water via the process. 

Additionally, aeration may remove iron or manganese from the environment by oxidizing these compounds to their insoluble form. Iron and manganese may produce strange flavors and discolor clothes when consumed in large quantities. These chemicals may be removed by filtering after they have been transformed into insoluble forms.

4. Oxidation

It is most often utilized in warmer regions and involves the utilization of natural bodies of water such as lagoons to enable wastewater to flow through for a predetermined amount of time before remaining in the water body for two to three weeks.

5. Sedimentation

Once big flocks have developed, they must be settled out, which is accomplished via a process known as sedimentation (in which the particles sink to the bottom of a settling tank). After coagulation and flocculation, the water is allowed to settle in the tank for many hours to allow sedimentation to take place. The material that has collected at the bottom of the tank is referred to as sludge, and it is taken from the tank for disposal. 

Water is pumped into a tank or reservoir that is securely closed. In addition to killing any residual germs or bacteria in the water, chlorine or other disinfection agents may also aid in keeping the water clean until it is distributed.

Water Treatment Plant India manufactures and supplies a diverse variety of sewer systems, waste disposal plants, sewage plants, and package water treatment facilities. Their complete range of facilities and services is in high demand in the pharmaceutical business, chemical manufacturing industry, and food processing industry, to mention a few industries.
