Typical Trickling Filter System
Sprinkler irrigation is a relatively simple treatment
technology used to volatilize VOCs from contaminated wastewater. The process involves the
pressurized distribution of VOC-laden water through a standard sprinkler irrigation
system. Sprinkler irrigation transfers VOCs from the dissolved aqueous phase to the vapor
phase, whereby the VOCs are released directly to the atmosphere.
Sprinkler irrigation can be utilized for any contaminant
that readily transfers from the dissolved phase to the vapor phase (VOCs). The target
contaminant groups for trickling filters are VOCs, SVOCs, fuels, explosives, and
The following factors may limit the applicability and effectiveness of the
- Regulatory approval may be difficult to obtain because of the potential of direct
release for contaminants to the atmosphere.
- Ponding of wastewater may result from heavy irrigation.
- Metal contaminated wastewater can't be treated.
- Performance may be effected by temperature.
- As CAA requirements become stricter, this technology may become obsolete.
A detailed discussion of these data elements is provided in Subsection 2.2.2 (Data Requirements for Ground Water,
Surface Water, and Leachate).
Since sprinkler irrigation is a new process, little detailed or meaningful
performance information is available.
