Odour Control in Sewage Treatment Plants: Mitigation Strategies and Anotec’s Role

Odour control in sewage treatment plants (STPs) remains a critical challenge due to the release of malodorous compounds like hydrogen sulfide (H₂S), ammonia, and volatile organic compounds (VOCs) during wastewater processing 2 . These odours not only affect nearby communities but also indicate inefficiencies in treatment processes, such as anaerobic decomposition in uncovered tanks or clogged pipes 3 5 . Below is a detailed overview of mitigation strategies and the role of Anotec in addressing these issues. Key Odour Mitigation Strategies for Sewage Treatment Plants Chemical Treatment Chemical dosing : Adding agents like calcium nitrate, ferric chloride, or deodorizing chemicals to neutralize odorous compounds is a common practice 6 . For example, sodium chlorite can oxidize sulfides, reducing H₂S emissions 6 . Anotec’s Anotec 0307 : A specialized formulation designed for fogging or hand application, this product targets odours at their source by neutralizing malodorous molecules. Its ...
