# Granular Organic Adsorption Media for Permeable Reactive Barriers (PRB)

Permeable reactive barriers (PRB) are designed for long-term control of contaminated groundwater plumes. Camp-Shinning supplies **granular organic adsorption media** suitable for PRB installations where hydrophobic organics such as oils, NAPL, PAHs, and PCBs require strong adsorption and stable hydraulic behavior.

## Why Adsorption Media Is Used in PRBs
– Hydrophobic organics are difficult to treat with oxidation alone
– PRBs need predictable performance over long time horizons
– Granular media supports permeability while providing adsorption capacity
– Passive treatment can reduce O&M requirements

## Typical PRB Use Cases
– Hydrocarbon-impacted groundwater at industrial sites
– Plumes with residual NAPL and dissolved hydrophobic organics
– Mixed organic contamination where polishing is required
– Barrier systems paired with other reactive materials

## Design Considerations for PRB Media
Key parameters often include:
1. Hydraulic conductivity and grain size selection
2. Residence time and barrier thickness
3. Expected organic loading and breakthrough planning
4. Installation method (trench, injection, or modular cells)
5. Long-term monitoring strategy

## Performance Advantages
– High affinity adsorption for low-solubility organics
– Granular format supports stable permeability
– Can provide long service life when properly designed
– Suitable for blended reactive zones with complementary media

## Packaging and Project Supply
Camp-Shinning provides 25 kg bags and bulk delivery coordination for PRB contractors, including logistics planning for staged installation.

## FAQ

### Can adsorption media be used as the main PRB component?
Yes. For hydrophobic organics, adsorption media can be a primary PRB component or part of a blended reactive zone.

### Does it maintain permeability?
Granular media is selected to support flow-through performance; design should confirm grain size and hydraulic conductivity.

### Which contaminants are most suitable?
Oils, NAPL-related organics, PAHs, and PCBs are common targets in PRB applications.

### How is PRB thickness determined?
Thickness is based on residence time, groundwater velocity, and required treatment performance under site conditions.
