Evoqua RJ Environmental Biological Odor Control
two-stage odor control system for complete odor removal. The system is a multi-media system which combines gas absorption, adsorption, and biological treatment to capture and eliminate organic and inorganic odors from wastewater process air streams. The unique combination of proprietary carbon media enables the ZABOCS system to treat three times the air volume compared to similar sized conventional biofilter systems, while also being able to start treating odors immediately with zero acclimation time. First Stage: The first stage uses a manufactured expanded clay media as the substrate for the biomassand removes 99% of the H2S as well as removing other odorous compounds. Second Stage: Activated carbon is used in the polishing stage to trap VOC’s and insoluble organic compounds that get through the first stage. The ZABOCS biofilter system can treat air flows up to 5000 cfm and H2S concentrations in excess of 100 ppm.
