Alternatives to odor and corrosion control in sanitary sewerage systems and treatment plants

ABSTRACT

This paper aims to consolidating the main characteristics, advantages and disadvantages of available methods in technical-scientific community to odor and corrosion control in sanitary sewerage systems and treatment plants, taking along an innovative approach on preventive solutions related to sewage systems design and operation with addition of chemicals or liquid phase aeration. The main beliefs of each technique are presented as well as the main guidelines for alternatives design. In addition, guidelines are given for corrective solutions design of covers and exhaust of potentially odorous sources, as well as a brief discussion of processes currently available in the technical-scientific community to the treatment of odorant odorous and corrosive gases.
