Description
Green Ladder Technologies’ sister company GES Biotek manufactures engineered, nutrient-rich, open-cell substrate from recycled glass material that would otherwise end up in a landfill. We offer site-specific media solutions to help create the ideal green environment for autotrophic and heterotrophic biofilter processes. GES Biotek provides all the services necessary to get your site up and running and keep it running at peak performance.
Technology
Cell-Max™ media is designed for the treatment of high levels of H2S in Bio-Scrubbers®, especially in low-pH environments. It is rigid and acid resistant, eliminating compaction or degradation while consistently achieving specified H2S removal rates.
Enhanced Cell-Max™ provides all of the benefits of high-performance engineered biofilter media (small footprint, short residence time, long media life) but at ¼ of the weight of comparable engineered media.
Biochemical Processes
- Autotrophic Bacteria: Think of these bacteria as the “solar panels” of odor control. They don’t require organic food; instead, they capture energy from inorganic sources, much like solar panels capture sunlight. In odor control, autotrophs use hydrogen sulfide as their energy source, converting it into harmless byproducts and carbon dioxide, which they utilize as a carbon source to build and maintain cell material. Our Cell-Max™ media supports an autotrophic ecosystem, optimized to target these compounds.
- Heterotrophic Bacteria: Acting as the “recyclers” or “composters” of the system, heterotrophic bacteria require organic material to thrive. They break down odorous volatile organic compounds (VOCs) — such as Methyl Mercaptan, Ethyl Mercaptan, and Dimethyl Sulfide — into simpler, odorless compounds. Similar to composters converting kitchen scraps into fertile soil, these bacteria decompose complex odor-rich organics into harmless byproducts. Our Enhanced Cell-Max™ media is designed to support this heterotrophic ecosystem.
Benefits
- Pressure Drop Plateau: Once the media bed is established and microorganisms have formed colonies, the pressure drop across the biofiltration system stabilizes. This indicates that the system has reached a point of equilibrium regarding its filtration efficiency.
- Fluctuations in Pollutant Concentrations: Hydrogen sulfide and mercaptan concentrations in the gas stream can vary over time. These fluctuations lead to changes in the population of microorganisms within the media bed.
- Microorganism Activity: As pollutant concentrations increase, microorganisms responsible for pollutant removal will proliferate. Conversely, when pollutant concentrations decrease, some microorganisms will die off.
- Biomass Accumulation: Over time, as microorganisms continue to grow and die off in response to pollutant fluctuations, sufficient biomass accumulates within the media bed. This biomass is essential for the biological removal of pollutants from the gas stream.
- Operating Pressure Drop: Over time, variations in microorganism growth may increase the operating pressure drop in the biofiltration system. The two main factors influencing this increase are the duration the media bed is in operation and the degree of fluctuations in hydrogen sulfide and mercaptan concentrations.
- Media Kernel Durability: The media kernel is impervious to the biofiltration environment. This means that it doesn’t break down or contribute to an increase in the pressure drop over time. This is an advantage compared to other biofiltration systems where some components will deteriorate.
At Green Ladder Technologies, we continuously work to improve our products and reserve the right to make changes in specification and design without notice. Minor variations can occur during the manufacturing process. This data is intended as guidance only.
