GES Biotek - Crater-Max® microbiological odor-control solution for Bio-Scrubbers® and Biofilters - spec sheet
Crater-Max ® Microbiological Odor-Control Solution FOR BIO-SCRUBBER® AND BIO-FILTERS
The porous Crater-Max® media used in the Bio-Scrubber®/Bio-Filter serves as part of the ecosystem for the growth of acidithiobacillus thiooxidans microorganisms. Crater-Max® media also contains the necessary iron content that, in a low pH environment, will create a chemistry of iron ions to support a colony of acidithiobacillus ferroxidans microorganisms. The media shall be of the type that the surface openings are not through-and-through, therefore eliminating any increase in static pressure over time due to the fouling of the pore structure. The Crater-Max® media shall be manufactured by GES Biotek, LLC. The porous media shall have a proven reliability record for biological growth with a minimum of 1,000,000 cubic feet installed over a five-year period, with at least five separate projects, based on actual installations in a low pH sulfuric application without degradation. The media utilized shall be acid tested and crushed, using no aggregate larger than 3” in diameter, ensuring a uniform surface area of a minimum of 10,000 square feet per cubic foot of media.
