ELIMINATING H2S ODOR AT THE SOURCE

OdorKnocker products are designed to eliminate H2S odors, not just mask them. Our Model RX and Odor Control Media work together to provide a long-term, reliable solution for manhole odor control. Here’s how they work:

The Model RX

The Model RX is built from 18-gauge, 304 stainless steel, hydraulically spun from a single sheet for maximum strength. It is designed to handle the toughest conditions, including corrosive gases, traffic vibration, and constant wear and tear. The Model RX allows proper airflow while eliminating odors, reducing long-term maintenance costs and preventing corrosion.

How the Media Works

OdorKnocker Media isn’t just absorbing odors – it’s eliminating them at the source. Made from recycled materials and EPA/OSHA compliant, this media converts H2S gas into iron pyrite (fool’s gold) through a chemical reaction, rendering the gas inert and harmless. Unlike absorbent products that eventually become saturated, our media binds with and converts H2S, providing a longer-lasting, more efficient solution.

Key Media Benefits:

• Non-Hazardous – Safe to handle, easy to dispose of, and non-toxic even when spent.\
• Long-Lasting Performance – One fill lasts 1-2 years, even in wet conditions.
• Low Environmental Impact – Made from recycled materials, aligning with sustainable practices.
• Easy Disposal – Can be safely disposed of as standard waste or even repurposed as garden mulch in some cases.

Why Does H2S Build Up?

Hydrogen sulfide (H2S) odors don’t just happen—they’re the result of real-world conditions common in many sewer systems. Understanding the causes can help you identify problem areas before they escalate.

Common contributors to H2S buildup include:

• Elevated temperatures (especially in warmer months)
• Turbulent or churning flow in sewer pipes
• Stagnant or slow-flow areas
• Proximity to pump stations or wastewater plants
• Commercial zones—especially alleys near restaurants or parking garages
• New subdivisions that haven’t reached design flow capacity
• Seasonal-use locations like:
  • Parks and campgrounds
  • Stadiums and golf courses
  • Trails, bike paths, and recreational areas

These conditions make certain manholes more vulnerable—and that’s where OdorKnocker Media proves its value.

Why Not Just Trap H2S?

Trapping odors might seem like a quick fix, but it can accelerate pipe corrosion and concrete damage, leading to costly repairs. The Model RX eliminates H2S odors without trapping harmful gases—allowing for proper airflow and reducing long-term maintenance costs.
