Effective Management of Toxic Gas in Water

Many water-related industries deal with toxic gases that pose significant risks to personnel, equipment, and the environment. Three of the most common toxic gases found in water treatment facilities include:

• Chlorine (Cl₂) – Used for water disinfection, chlorine is a powerful oxidizing agent that can cause severe respiratory issues, eye irritation, and even fatalities in high concentrations.
• Sulfur Dioxide (SO₂) – This gas is commonly used in dechlorination processes but can cause respiratory problems and environmental harm if not properly contained.
• Ammonia (NH₃) – Often used in water treatment to form chloramines, ammonia is a hazardous gas that can lead to serious health risks when inhaled.

Why Protection is Needed

Protection against these toxic gases is essential to ensure human safety, environmental protection, and productivity.

Employees at water treatment facilities must be protected from exposure to harmful gases that can cause serious health complications. The environment and people in surrounding areas are also at risk. Uncontrolled releases of toxic gases can have devastating effects on nearby communities and ecosystems.

Beyond health and safety concerns, gas leaks can lead to shutdowns, resulting in costly delays and inefficiencies in water treatment operations.

EPA Requirements

The U.S. Environmental Protection Agency (EPA) requires water treatment facilities handling significant quantities of chlorine or sulfur dioxide to implement comprehensive Risk Management Plans (RMPs). These regulations aim to minimize accidental releases and ensure facilities have appropriate mitigation measures in place. Installing proper gas filtration and scrubber systems can qualify facilities for reduced regulatory scrutiny under Program 1.0 of the EPA’s RMP guidelines.

Chlorine Gas Removal with Safetysorb

PureAir Filtration’s Safetysorb media is specifically designed for chlorine gas removal. Key features include:

• High Adsorption Capacity – Effectively captures and neutralizes chlorine gas
• Non-Toxic – Ensures safe handling and disposal
• Landfill Disposable – The reaction byproducts are harmless salts that can be safely disposed
• Non-Flammable – UL-certified for safety, providing a safer alternative to activated carbon-based solutions

Why Dry Scrubbers Are the Best Solution

PureAir Filtration’s Emergency Gas Scrubber (EGS) is an ideal solution for facilities looking to protect against toxic gas releases.

Compared to wet scrubbers, dry scrubbers offer several advantages:

• Lower Ownership Costs – Minimal maintenance and operational costs
• Reliable Performance – Consistently effective at both low and high gas concentrations
• No Hazardous Liquids – Eliminate the need for corrosive liquid chemicals, making them safer and easier to operate

A NOTE ON ACTIVATED CARBON: While activated carbon is widely used in the industry, it is not suitable for chlorine gas due to the risk of bed fires. The material can trigger an exothermic reaction, generating enough heat to ignite a fire, making it a hazardous choice for chlorine gas applications.

Sulphasorb 2™

For efficient neutralization of acidic gases, PureAir Filtration offers Sulphasorb 2™, a highly effective media designed to target:

• Chlorine (Cl₂)
• Hydrogen Sulfide (H₂S)
• Sulfur Dioxide (SO₂)

This advanced media provides enhanced fire resistance and is formulated with high-grade activated carbon and alumina for superior performance.

LIFEGARD™ for EGS

PureAir Filtration’s LIFEGARD™ system is an essential addition to the Emergency Gas Scrubber, offering:

• Real-Time Monitoring – Tracks media usage and detects small traces of chlorine gas
• Peace of Mind – Provides assurance that gas scrubber media is functioning optimally
• Instant Alerts – No delays in detecting harmful gas presence, ensuring rapid response
