Odor control in WWTPs
Controlling odor emissions at wastewater treatment plants (WWTPs) is a priority objective for management entities, in order to ensure the well-being of workers and minimize the impact these facilities have on the environment.
Bioconservacion has the solution to treat the emission of odor-causing gases, ensuring compliance with environmental regulations and improving the quality of life of workers and neighbors.
In this article, we will present a real and successful experience in Poland, specifically at the Poznań wastewater treatment plant, where BION air filtration systems have been implemented.
At the end of 2014, the Poznan wastewater treatment plant (PolandI) completed a project to modernize its facilities, renovating and expanding the existing plant to be able to reach a treatment capacity of an average flow of 250,000 m3/day, in compliance with European and national regulations.
Thanks to this project, wastewater treatment coverage is expected to reach 99.6% by 2020, reducing wastewater discharge to the Warta River by 33,000 m3/day.
Moreover, the modernization will allow the reuse of almost 100% of the sludge. This will be possible thanks to the application of this sludge as landfill cover and/or as raw material for bio-fuel production.
In addition, the project contemplated investments for the reduction of odor emissions, significantly improving the living conditions around the plant in order to restore the attractiveness of this area.
The total air flow is 48,000 m3/h.
After a first treatment by a Biotrickling phase, the air flow is divided into four 12,000 m3/h sub-lines.
The air flow of each of these sub-lines is passed through a double bed adsorption scrubber, where each bed is purifying 6,000 m3/h.
The filter media recommended by Bioconservacion for this project:
A specific mixture of BION Carb OX and BION KOH, for H2S and mercaptans removal.
