Life quality is determined by the quality of available water resources, but over the past ten years, the water crisis has been the main environmental worry.
The significance of sewage treatment plants is the main topic of this article. We must be aware about how STPs help to prevent water pollution.
What are the risks associated with water pollution?
Due to a rapidly growing economy and concomitant population growth, water contamination has dramatically increased in India. Today's rivers and water supplies are more contaminated than ever before, according to the nation's top pollution control agencies. Water contamination currently increases the risk of water scarcity, which new processes have attempted to alleviate.
The issue of pollution has expanded alongside industrialisation as it has moved around the world. Many factors, including home and industrial contaminants, are causing water resources to become contaminated. Sewage and wastewater account for almost half of all ocean contamination. From 5 to 10 billion tonnes of industrial waste are produced worldwide each year, much of it is dumped untreated into rivers, oceans, and other waterways. Thus, there are significant risks involved in their immediate discharge into a live ecosystem.
What is the role of STP in reducing water pollution?
Wastewater should always be treated with sewage treatment plants to remove any substantial pollutants. Wastewater collected from industrial and domestic sources is treated in sewage treatment facilities.
Heavy solid pollutants, organic wastes, and toxic compounds are present in both industrial and home sewage. Before wastewater is disposed of in living systems, the sewage treatment process must be effective in treating and eliminating the dangerous wastes, making the wastewater safe.
Sewage treatment process
Liquid contaminants rise to the top during the clarification process. Eventually, circular clarifiers are primarily used to remove liquid pollutants like oil floating and grease. The process of sludge activation known as aeration utilizes enormous blowers known as aerators.
The aerators provide oxygen to the bacteria since the organic pollutants have a high BOD (Biological Oxygen Demand), which causes sludge to accumulate and be eliminated later in the secondary stage.
Also, there are either chemical or physical contaminants in the secondary stage treated water. The harmful contaminants are disinfected in the tertiary phase, making it safe to dispose of the treated water, using RO Plants as well as UV purification systems.
Sewage treatment plants aid in reducing the release of dangerous contaminants into natural water sources, hence reducing water pollution.
To ensure the health of the plants, animals, and humans that rely on the environment, we may cooperate to maintain the environment clean. The installation of sewage treatment plants needs to be made public through a variety of media venues. By avoiding the use of pesticides, using ecologically friendly detergents, and refraining from pouring oil down drains, we can all do our part to help prevent water pollution.
And as nations and continents, we may work to enact rules that will help us make pollution less nations and the earth less polluted. Together, we can reduce the issue of pollution and improve the globe.
