1. ODOR CONTROL
Odor control is increasingly important as congestion
increases, treatment facilities become constrained to
populated areas and regulations grow. At left are upper and
lower views of mechanical odor control scrubbers serviced
with hypochlorite and ferric chloride to remove hydrogen
sulfide from the bulk chemical storage below left.
Below is an open bed lava rock biological odor filter under
construction. The air distribution system being assembled will
be covered with lava rack, and a growing bed for local
vegetation. Humidified air and irrigation will sustain the
vegetation and microorganisms in the filter bed which
biologically degrade odors. If space allows, the bio-filter system
provides a sustainable approach to odor control and removal .
