Integrated Odor Control for Solids Handling Operations

Untitled Document

Solids handling operations and solids holding facilities are often major sources of odor at wastewater treatment plants. Hydrogen sulfide and other odorous compounds generated during primary settling and solids holding are released during solids processing. For dewatering processes, belt presses in particular are prone to severe odor problems. Belt press rooms are notorious for having high hydrogen sulfide concentrations, which can cause corrosion of equipment and, in some cases, pose a health hazard to workers. This case study demonstrates that effective, yet economical, odor control of solids handling operations can be achieved through an integrated approach combining both liquid-phase and vapor-phase treatment.
