Emissions of hydrogen sulfide and methane are two the major concerns in sewers, causing corrosion, odour health problems. This study proposed a new free ammonia (FA)-based approach for controlling biological production sewers. is based on discovery that FA contained urine wastewater strongly biocidal to anaerobic sewer biofilms. Long-term operation laboratory reactors, with one being dosed other raw sewage as control, revealed effectiveness approach. The results showed dosing real at...

Corrosion and odor induced by sulfidogenic processes is a worldwide issue in environmental engineering. This study focuses on neglected, but critical process, conversion at the water-sediment interface, to optimize prediction control of sulfide sewers. A novel situ, high-resolution measurement method based diffusive gradients thin films technique was established for first time use sewer systems. The results showed that, shear velocity (i.e., ∼0.07 m/s), key factor dominating activity surface...
