Abstract
Wastewater pumping stations generate offensive odors due to the presence of sulfur compounds, this can cause inconvenience to the communities near these places. A biological system was implemented for the reduction of hydrogen sulfide in North Wastewater Pumping Station of Santa Marta. Were designed, built and installed two biofilters in acrylic with a height of two meters and an inside diameter of 20,32 centimeter, loaded with sugar cane bagasse as a means of support . The system available of permanent wastewater supply for maintains moisture and nutrients for microorganism, as well as metering, control and data acquisition devices. The results showed reduction of high loads of hydrogen sulfide and removal efficiencies of up to 100%, however it required a stabilization period of 14 days, to maintain the maximum efficiency gains.
