An Overview of Performance Evaluation of Sewage Treatment Plant

Abstract

Sewage whether treated or untreated, ultimately discharge in lakes, rivers, streams, and oceans. We consider groundwater as pure, but unfortunately, sewage is one of the major reasons behind wastewater-associated diseases. Nearly 78% of the water flows back to the environment without any treatment. This can lead to numerous health and environmental problems so it is better to treat wastewater before disposal and further proper management can help in meeting the public’s water demand. As per today’s scenario, a number of innovations are required to operate treatment plants at high efficiency because of increasing domestic, commercial, and industrial waste. And this rise is taking place due to several reasons – urbanization, increasing population, economic development, and improved living conditions, etc. Nowadays people of both urban and peri-urban areas are using wastewater to irrigate their crops, often because they do not have any alternate source of irrigation water. New technologies are continuously being introduced in the sewage treatment plants to exhibit good performance. The paper focuses on reviewing the various sewage treatment methods and their results.

Fast Tracking and Detection of Organic Matter in an Urban Sewage Treatment Plant Using Fluorescence Spectroscopy and UV-Vis Absorption Spectroscopy

“…Urban sewage treatment plants are recognized as effective tools in the removal of COD from domestic sewage [4]. Through successive stages of physical treatment, biochemical treatment and advanced treatment, these facilities degrade macromolecular refractory organic compounds in sewage into smaller molecular organic molecules, subsequently transforming these molecules into inorganic substances for COD removal [5].…”
