Compartmentalization of contents of a facultative lagoon into two separate
zones improves the economic efficiency of the lagoon for emission control
by eliminating macroscopic mixing between the zones, while allowing
odor-causing compounds from the anaerobic zone to pass into the aerobic
zone. A physical barrier compartmentalizes or divides the lagoon contents
into an upper aerobic zone and a lower anaerobic zone. Odor-causing
compounds biologically convert within the aerobic zone into olfactorily
inoffensive compounds that release into the atmosphere. An aeration device
aerates the aerobic layer. Emission of hydrogen sulfide, ammonia, volatile
acids, phenols and other odorous gases from anaerobic wastewater and
manure lagoons or basins is reduced.
