STUDY ON SEWAGE TREATMENT PLANT AT ST. MARTIN'S ENGINEERING COLLEGE

Abstract

The treatment of sewage is an essential aspect of maintaining environmental health and ensuring sustainable urban development. With increasing urbanization and population growth, the need for effective sewage treatment systems has become more pronounced, particularly in educational institutions, where large populations of students, faculty, and staff generate significant volumes of wastewater. This study focuses on the design, operation, and performance of the sewage treatment plant (STP) at St. Martin’s Engineering College, located in Hyderabad, India. The objective is to evaluate the efficiency of the existing STP, assess its treatment capacity, and identify potential areas for improvement in the treatment process, in line with environmental regulations and sustainability goals. The sewage treatment plant at St. Martin’s Engineering College Is designed to handle the wastewater generated from the college’s academic buildings, hostels, and other facilities. The STP employs a conventional treatment process consisting of primary, secondary, and tertiary treatment stages to ensure that the effluent meets the required standards for discharge or reuse. In this study, a detailed assessment of the various stages of treatment is conducted, with a particular focus on the biological, chemical, and physical treatment methods used in the system. Primary treatment includes the removal of large solids through screening and sedimentation, while secondary treatment involves biological processes, such as activated sludge or biofilm systems, to degrade organic matter. Tertiary treatment aims to further purify the water through filtration, disinfection, and, in some cases, nutrient removal to ensure that the treated water is safe for discharge into local water bodies or for reuse within the college premises.
