Case Study of Deterioration of Mansar Lake and Comparative Study of FAB and SBR Technologies in Sewage Treatment Plant

Abstract

The deterioration of Mansar Lake, a significant tourist attraction and a vital water resource in India, has become a matter of concern due to the discharge of untreated sewage and industrial effluents. The present study aims to investigate the factors leading to the degradation of Mansar Lake and the effectiveness of two advanced sewage treatment technologies, Fixed Activated Beds (FAB) and Sequencing Batch Reactors (SBR), in treating sewage waste. The study begins with a comprehensive analysis of the factors contributing to the degradation of Mansar Lake, including the inflow of untreated sewage, industrial effluents, and agricultural runoff, as well as the impact of climate change and anthropogenic activities. The research then moves on to the comparative study of FAB and SBR technologies, evaluating their performance in terms of pollutant removal efficiency, energy consumption, and operational costs. The results of the study show that both FAB and SBR technologies are effective in treating sewage waste, with SBR technology having a slight edge in terms of pollutant removal efficiency. However, FAB technology is more cost-effective and energy-efficient, making it a more viable option for developing countries with limited resources. The study concludes with recommendations for the implementation of FAB technology in the sewage treatment plant serving Mansar Lake, as well as the need for stricter regulations and enforcement to prevent the inflow of untreated sewage and industrial effluents into the lake. The study also emphasizes the importance of public awareness and education in preserving the lake's ecological balance and promoting sustainable tourism practices.
