Engineering & Process Integration for Air and Water Emissions Control

Wastewater treatment plants (WWTPs)—both municipal and industrial—present complex engineering challenges. In addition to water purification, they are significant sources of airborne emissions from biological processes, chemical dosing, and sludge handling. Key pollutants include:

Volatile Organic Compounds (VOCs) from industrial influent and surface aeration
Hydrogen Sulfide (H₂S) from anaerobic digestion and sludge tanks
Ammonia (NH₃) from nitrogen removal and digesters
Methane (CH₄) from biogas systems and sewer lines
Odorous Compounds such as mercaptans, amines, and organic acids

Why Emissions Must Be Managed

Odor & Community Relations

Persistent odors affect surrounding communities and risk complaints or reputational damage

Worker Health & Safety

Gases like H₂S and NH₃ pose serious risks even at low levels

Regulatory Compliance

Strict VOC and odor limits apply; non-compliance can halt operations

Asset Protection

Corrosive gases shorten equipment life and increase downtime

Biogas Utilization

Cleaning biogas improves energy recovery and protects CHP or upgrading systems
