Abstract
In order to comply with current environmental standards, wastewater treatment plants and other industries have found it necessary to seek out methods for gaseous emissions treatment. Consequently, such industries must address hydrogen sulfide odor emissions. Biofiltration, responsible for the removal of a large number of gaseous pollutants including hydrogen sulfide, is a viable option. Offering interesting guarantees for the environment, this technique is economically attractive for companies where savings can be obtained in the treatment of odors through the inputs used in established treatments. Taking advantage of the characteristics of biofiltration may extend the use of the technique for the elimination of certain gaseous pollutant compounds and provide a solution to hydrogen sulfide odor emissions. It is for this reason that the present research study has been developed and why focus has been given to the construction of a pilot biofilter system to remove hydrogen sulfide in order to determine the maximum removal capacity of a biofilter. The methodology used for the implementation of the biofiltration system was: Preparation of support material; inoculation of sulfur oxidant bacteria; preparation of nutrients for compost; and the operation of the biofiltration system. Each of these stages was executed successfully whereby achieving the efficient operation of the system reflected in the final result which corresponds to removing 1,250 ppm and 1,300 ppm of hydrogen sulfide with an efficiency of 100%. With possibilities for implementation into any type of Sewage Treatment Plant, the biofiltration system is no doubt a feasible technique for the mitigation of odors derived from hydrogen sulfide.
