Biotrickling filters in Sant Andreu de Llavaneres

Retrofitting of two chemical scrubbers into biotrickling filters in Sant Andreu de Llavaneres (Catalonia)

Scope: Urban sewage treatment plant
Results: This is the first retrofitting of chemical scrubbers into biotrickling filters ever made in Spain. With a return on investment time below 18 months, the two-stage system complemented with a conventional biofilter showed an uninterrupted efficiency of around 99% for both VOCs and H2S since its first week of operation. Neighborhood complaints were completely cut off since then. In operation since 2010, the equipment operates with the same efficiency and reduced costs as the first day.
