WHY WASTE WATER TREATMENT IS IMPORTANT?

  Wastewater treatment protects humans and ecosystem Wastewater contains elements toxic to humans and the ecosystem. Wastewater treatment facilities help to purify the water and eliminate situations like what is currently seen in developing countries. Unclean water poses significant health risks, accounting for 1.7 million deaths annually, of which over 90 percent are in developing countries. 2  Several water-related diseases, including cholera and schistosomiasis, remain widespread across many developing countries, where only a very small fraction (in some cases less than 5 percent) of domestic and urban wastewater is treated prior to its release into the environment 3 . Wastewater treatment also protects the ecosystem. Fish and aquatic life require fresh water. When their water environment is laden with wastewater, they cannot survive. If chemicals, such as nitrogen and phosphates, enter streams, rivers or large bodies of water in excessive amounts, it causes excessive...

Role & Importance of Sewage Treatment Plant (STP)

  Importance of Sewage Water Treatment Plants: Over the past few decades, sewage and research and technology have evolved. The population of the world is expanding fast, and people are looking for natural resources in clean water sources such fresh rivers, wells, and groundwater. Natural resources will eventually become scarcer. This has caused the emphasis to shift from preventing pollution to reducing its effects. Wastewater cannot now be disposed of in land or water bodies without suitable and efficient treatment procedures. India has the second-largest population in the world and the highest population density in its Gangetic plains as well as other parts of the country. It also boasts 4% of the total fresh water available on Earth. India must therefore work towards sustainable water use, water recovery, and water re-use in order to satisfy the basic need for water for its citizens.   Maintenance of Sewage Water Treatment Plants: Utilising reliable and effect...
