Comparative study of centralized and decentralized system of wastewater treatment and study of sewage treatment plant in the City of Ujjain (India)

Wastewater treatment has been evolved from the past years from centralized treatment systems to the household treatment works as of now. And it is emerging in the developing countries as well, so I have done the study of both decentralized as well as centralized treatment process and had seen their advantages and disadvantages. Also, I have worked with SMART city project where I studied the treatment technology of Sequencing Batch Reactor (SBR) and why it is better than other technologies.
