GES Biotek

Microbiological Odor Control Solutions

GES Biotek

Headquartered in Batavia, IL, GES Biotek, LLC is one of the nation's leading environmental solutions firms specializing in nutrient-rich open-cell substrate.

For more than 25 years, GES Biotek has been manufacturing open-cell substrates from 100% naturally occurring materials. Its lineup of Cell-Max™, Enhanced Cell-Max™, Crater-Max®, Fiber-Max™, and GES Nutrient products are used throughout the US in all industries requiring the treatment of complex odors, VOCs, and high or low levels of H2S typically found in municipal wastewater.

Developing newer and greener technology over the past 15 years, GES has been at the forefront of manufacturing open-cell substrate from recycled glass material that would otherwise end up in a landfill. This media mitigates odor compounds in the parts per billion range.

GES Biotek was originally incorporated in 1997 to market the first Bio-Scrubber®. While continuing to commercially manufacture fully engineered and integrated systems for the next decade, GES recognized the need for natural ecosystems. This led to the development and manufacturing of improved biological media, nutrients, and components.

This realization created a recipe for success. Over the last two and a half decades, GES has supplied over 3 million cubic feet of bio-oxidation media to the municipal wastewater industry alone. GES also supplies products for horticultural industries like hydroponics, aquaponics, green roofs, vertical walls, water filtration, and other markets. All that said, GES is just getting started.

GES Biotek is committed to providing green product solutions for the next generations' demands—solutions that are good for people, good for the environment, and good for the planet.


  • Enhanced Cell-Max™

    Enhanced Cell-Max™ provides all of the benefits of high-performance engineered biofilter media (smaller footprint, shorter residence time, longer media life), but at ¼ of the weight of comparable engineered media. This allows for significantly lower project costs.

    Enhanced Cell-Max™
  • Cell-Max™

    Cell-Max™ media is designed for the treatment of high levels of H2S in Bio-Scrubbers® (biotrickling filters). It is rigid and acid resistant, therefore eliminating compaction or degradation while consistently achieving specified H2S removal rates.

  • Fiber-Max™

    Fiber-Max™ biofilter media is a proprietary blend of organic materials for the removal of complex odors and VOCs. This fibrous cellular substrate material is manufactured only from trees and large tree branches.

  • Crater-Max®

    Nature’s billion-year-old natural ecosystem for sulfur-oxidizing bacteria. Crater-Max® is specifically engineered and processed for chemical resistance, size, and optimum surface area for H2S removal.

  • GES Nutrients

    GES 1578 Super Nutrients are formulated as a supplement to enhance the growth of acidithiobacillus thiooxidans and ferroxidans microorganisms in a biological scrubber ecosystem where the primary food source is H2S in the foul air stream.
