• Odor Control Strategyo Identify Sources of Odors
• Septage Receiving Area• Screening and Grit Removal• Equalization Tanks• Processing – Dewatering• Filtrate
oEstimate Degree of Control Required based on proximity of downwind receptors
oEvaluate OptionsoSelect Appropriate StrategyoDesign and Construct

•Odor Control StrategyoBest Management Practices• Use quick-disconnect fittings• Avoid “Free Fall” of septage• Provide washdown facilities
for spills• Ventilate tanks to odor control
system• Everything inside!

•Available TechniquesoBiofilters
-Passing odorous air through a media containing microbial populations
-Microbes use the odorous compounds as a food source
-Media must be kept moist and air must have good paths through media
-Requires long contact times and low velocities
-Systems come in a variety of designs and media configurations
