Odor control technology at wastewater treatment facilities has varied over the last 30 years. Today, biofiltration and biotrickling systems are clearly the control technologies of choice in this era of “going green” and implementing “sustainable solutions”, because they use less energy and require no chemicals. But buyer beware, biological systems generally cost more to install and require more real estate. Today, when an owner considers odor control for the first time, they are greatly influenced by the green/sustainable benefits and desirable operating costs of biological systems. But why would owners switch if their existing systems have been in compliance for years? Perhaps concerns about: equipment age; new permit requirements; persistent complaints; and performance could make an owner reflect on whether to maintain, upgrade or switch technologies. The City of Los Angeles had to address just such a concern at their Hyperion Treatment Plant with three odor control systems for their solids handling areas.
