Sewage treatment represents a crucial environmental process where bacteria play a vital role in breaking down organic matter and purifying wastewater. The use of bacteria in sewage treatment has revolutionized the way we handle waste management, providing an efficient and environmentally friendly solution to water pollution. Modern wastewater treatment facilities rely heavily on bacterial processes to achieve high-quality effluent standards while minimizing environmental impact. The biological treatment approach has evolved significantly over the past century, incorporating advanced technologies and understanding of microbial ecology to optimize treatment efficiency.

Domestic sewage treatment plants play a crucial role in maintaining public health and environmental sustainability. They are designed to treat wastewater generated from households before it is released back into the environment. Understanding how these plants operate is essential for appreciating their importance in modern society. This article will explore the various processes involved in domestic sewage treatment, the technologies used, and the benefits they provide.
