How A Sewage Treatment Plant Works?

Sewage treatment plant plays an important role for the mankind. The main function of these plants is to make the water of the sewage clean that comes from home, commercial and industrial sectors. The treatment of sewage water has become the need of the hour as it stops spreading the diseases and illness caused by the sewage water. It helps society in making the water as well as environment clean. The sewage treatment plant works composed of 3 stages that make its working more efficient. The three stages of these plants include the primary stage, the secondary stage and the tertiary stage.

In the primary stage, the contaminants that are easy to eliminate are taken out from the wastewater. These substances may include oils, grease, and fats that can be easily removed from the surface area. The solids things like grits, stones, rocks, etc. are strained.

At the secondary stage, the removal of biological contaminants in wastewater takes place. A number of methods are processed there to eradicate the unwanted elements. This stage is considered as the important stage of the treatment plants.

At the tertiary treatment, which is the last stage of the plant, the water is get cleaned purely to get discharged in the environment. This is composed of man-made or artificial systems that help in filtration. At this stage, the nitrogen and phosphorous content is eliminated from the water. In addition to this, the water is further disinfected using chemicals like chlorine as well as treatment of UV.

Through these stages, the final water that comes out is clean and free from pollutants that can be safely released to the environment.

Importance of Sewage Treatments Plants for our environment

Sewage Treatment Plant

Even today, most of the developing countries discharge their industrial or domestic waste through water without any treatment. There are only few countries who discharge the waste water after giving primary treatment. But this treatment is not sufficient for environments and its inhabitants. Around the world, water is responsible of about 80% of diseases. Thus, treating water is very important so as to save environment from water bore diseases such as typhoid, cholera, jaundice and more. For the said purpose sewage treatment plant are designed, mainly to treat the sewage water and remove the most of contaminants from the waste water and sewage water. This treatment includes physical, biological and chemical processing to remove contaminant. In short, sewage treatment plants act as aid for treating water and giving back clean water to environment.

Overview

Sewage treatment plants are implemented to provide an environmental friendly fluid water or solid waste that is suitable for use. To built effective sewage plant, appropriate conveyor and infrastructure has to be built to regulate sewage water on timely basis. The quality and amount of treatment to be given varies from water to water. Some sewage water requires less treatment while other requires heavy and specialized treatment to make it an effluent fluid. Generally, most of the waste water is treated thorough sedimentation process. In this solid particles are separated from waste water.

Sewage Plants and World

With the growing health awareness and scarcity of water worldwide, many countries are implementing sewage treatment plants so as to reuse the same water by cleaning it. Since water is renewable resource, same water can be used for different purposes, if properly treated. Sewage water not only made the water contaminant free but also made it available for re-use.

Many developed countries had implemented sewage treatment plants to encourage re-useability of water. Israel have about 50% of agricultural water for irrigation purpose which is supplied through reclaimed sewer water. Singapore is the only country that has implemented sewage treatment plants to reuse the sewage water for drinking purposes on a production scale. India also have contributed towards environments by installing water and waster treatment plants for treating polluted water.

Every developed and underdeveloped cites / states produce high amount of waste-water. To nullify its effect on the environment, a number of Sewage Treatment Plants have been developed in their infrastructure. In India, the problem of waster water is huge although there are a number of sewage treatment plant.

Here a question arises. If the aforesaid statement is true, then why there is huge problem of untreated waste-water in India?

The answer is simple – Bad Infrastructure and Steep Increase in Population

Bad Infrastructure : Amongst the huge number of sewage treatment plants developed in India, most of them are outdated and in bad conditions. Such plants are not outfitted with modern equipment and hence they are featured with low efficiency. The funding provided by the Indian Government is being misused and there are very few modifications done to improve the infrastructure of existing plants.

Steep Increase in Population : India is the country which is associated with exponential growth in population. This one factor has proven to be enough in nullifying the efforts Govt. of India towards betterment of Sewage Treatment Plants.

I believe that irrespective to these factors, new Sewage Treatment Plants should be designed & developed and the old Waste Water Treatment Plants should be revamped with innovative equipment. The remodeling of old plants will not only enhance its functionality, it will also augment the capacity rate of water-water treatment. If new initiatives undertaken by the govt. are implemented honestly, then this problem can be resolved to a highest extent – making this new era, a cleaner one.
