Wastewater treatment plants 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. Several water-related diseases, including cholera and schistosomiasis, remain widespread across many developing countries, where only a very small fraction of domestic and urban wastewater is treated prior to its release into the environment. Wastewater Treatment Industries are of great importance which can save ecosystems as well as decrease health risk for living beings.
