Water is one of the most basic necessities which are needed for cervical on the Earth. Water covers 71% of the total area of Earth. However, it is no secret that it is a struggle to find pure water in all this abundance, only 0.5% of fresh water is available to access.
Thus, the technological advancements urged people to loom for alternative ways to acquire freshwater which can be used by them. Thus, several water treatments are done to make it appropriate for specific end-use. Potable water converts to sewage after use which then has to be treated in order not to cause too much eutrophication of lakes, rivers, seas.
Water has to be disinfected in order to remove any microorganisms present in the water. Feces can be a source of pathogenic bacteria, viruses, protozoa, and helminths. The destruction of microbial pathogens is essential, and commonly involves the use of reactive chemical agents such as suspended solids, to remove bacteria, algae, viruses, fungi, and minerals including iron and manganese. These substances continue to cause great harm to several lower developed countries that do not have access to water purification.
The process of water treatment involves 4 steps which are:-
1.COAGULATION AND FLOCCULATION- In this step, particles of positive charges are released into the water which will enable neutralizing negative particles of dirt and other impurities dissolved in the water. Then particles bind with chemicals to form larger particles called floc.
2.SEDIMENTATION– When the flock settles down in the tank given the concentration of its weight. The settling process is called sedimentation.
3.FILTRATION– After the settling process. The clear water passes through a series of filters to further purify it, the filters are several agents capable of removing impurities. The agents are sand, gravel, and charcoal in order to eradicate dissolved particles such as parasites, dust, bacteria, viruses etc.
4.DISINFECTION- After the filtration step, the water is doused in disinfectants like (chlorine, chloramine) to kill any remaining parasites, viruses, or germs before it is piped to homes and businesses. Thus, the alkaline taste which you experience sometimes is because of these chemicals only.
Sewage or impure water poses a serious threat to all aspects of the environment as well as human beings It harms the farmlands as the untreated water contains chemicals which seep into the crops grown and letter on consumed by human beings and causes various diseases.
The area that is irrigated with untreated water spans around 30 million hectares of land. It also leads to pathogenic pollution and has direct health effects on developing and underdeveloped countries. Water pollution is a long-debated topic and is prevalent in all parts of the world, having a dramatic effect on lives and flora and fauna around us. Thus, if the water is left untreated the world will further be exposed to a series of treacherous diseases and unknown phenomena which will not be controllable and surpass our capabilities of deriving fresh water. We believe in treating water in an eco-friendly manner to restore the quality of water and reduce the harm caused by it.
