RE-ENGINEERED MEDIA
Cell-Max Plus
GES Cell-Max Plus is a next-generation engineered inorganic substrate specifically developed to maximize biological hydrogen sulfide (H2S) removal performance in high-load Bio-Scrubber® and Biofilter systems.
Improvements:
- Greater Rigidity (crushing load of 13,000 lb/ft2 at 15% strain)
- Lighter Weight (dry bulk density of 10.5 lb/ft3)
- Higher Surface Area for Microbiological Colonization (400,000 m2/m3)

RE-ENGINEERED MEDIA
Enhanced Cell-Max Plus
GES Enhanced Cell-Max Plus expands upon the proven structural benefits of Cell-Max Plus by integrating a next-generation proprietary, engineered nutrient and mineral matrix directly onto the substrate.
Improvements:
- Greater Rigidity (crushing load of 13,000 lb/ft2 at 15% strain)
- Lighter Weight (dry bulk density of 12.1 lb/ft3)
- Higher Surface Area for Microbiological Colonization (49,000,000 m2/m3)

Fir Bark Nuggets
Fir Bark Nuggets are an organic, fibrous, and coarse material derived from the outer bark of Douglas Fir or other fir species. Screened and graded to a particle size of 13 inches, this natural material is used as a protective top layer over biological filter beds.
- Maintains Consistent Humidity
- Traps VOCs and Bioaerosols
- Supports Microbial Activity
- Prevents Solar Degradation
- Reduces Compaction & Maintenance
- Prevents Media Displacement

Crater-Max®
Crater-Max® is specifically engineered and processed for chemical resistance, size, and optimum surface area for H2S removal. Crater-Max® has been successfully utilized in numerous Bio-Scrubber® (biotrickling filter) applications and as a base layer to significantly extend the life of organic Biofilter media.
- Natural Ecosystem
- Sulfur-Oxidizing Bacteria
- Corrosion Resistant

Cell-Max
An extremely lightweight, chemically resistant substrate made from 100% recycled material in the USA, Cell-Max maximizes surface area and serves as an integral part of the ecosystem for acid-thiobacillus bacteria growth.
- Acid Resistant
- Won't Compact or Degrade
- Treats High Levels of H2S
- Lightweight
